@@anttimaki8188 I install network cabling for a living and we like to use the Panduit Mini-com jacks, no punch-down tool required, and I find they are a lot faster on terminating and entire closet.
@@NehpetsNosliw I only do these occasionally, comes with electrician Job. I use whatever the boss has bought. Havnt seen punchdowns for a while though, mostly these clipping ones. Then theres those that got a tool that punch and cut all 8 wires simultaneosly. But If you only do these like every other month its kinda hard to sell the idea to boss :)
Just a job.. here in Russia we use only Cat 5. Speeds over 1G are only reachable with fiber-optic. Cat 6-8 are not acceptable because of money/speed proportion.
Who would have expected (back in the days of the 80's cat3-4) to be running 2GHz over twisted pair -it was generally accepted such signals were within the relm of coax.
I did Cat 8 because all my walls were torn out during a renovation. I figured there’s no easier time to just completely future proof my home network. Yes it was extremely expensive with the keystones and field terminations but a $2000 investment beats the hell out of having to redo it at somepoint.
Cat 5 was the latest tech when I did Cisco networking in high school and college and 5e came out shortly after. I wired my home with cat 5 and 5e and did a few small offices where I was doing build outs as I was a pro painter and did framing, drywall, and electrical....pretty much everything for typical commercial buildings. Things change fast and I have only had to do a few patch cables in the last 10 years or so.
Folks, please don’t believe everything you see on Amazon. I work on both the US and global standards development organizations that develops all of the cabling category standards and I’m going to provide a few facts about the different categories of cables and their constructions/specifications. UTP=no shielding at all. F/UTP=unshielded pairs with an overall foil shield. Sc/UTP=unshielded pairs with a screened (braided) shield. F/FTP=shielded pairs with overall foil shielded. Sc/FTP=shielded pairs with screened shield. Cat5e through cat6 can be constructed with any of the above depending on the users requirements. Cat7 and up must be Sc/FTP because of the extended frequency range. The shielded pairs mitigate internal crosstalk and the screen mitigates alien crosstalk between cables in a bundle. Cat5e=100 MHz, 1Gb/s at 100m, any connector style. Cat6= 250MHz, 1Gb/s at 100m, 10Gb/s at 55m, any connector style. Cat6A= 500 MHz, 10Gb/s at 100m, any connector style. Cat7= 600 MHz, 10Gb/s at 100m, only EC7, GG45 or TERA connectors (google them), RJ45 not supported. CatA= 1000 MHz, 10Gb/s at 100m, 25Gb/s at 50m, only EC7, GG45 or TERA connectors, RJ45 not supported. Cat8.1= 2000MHz, 10Gb/s at 100m, 40 Gb/s at 30m, any connector style. Cat8.2=2000 MHz, 10Gb/s at 100m, only EC7, GG45 or TERA connectors, RJ45 not supported. Multigig/NBaseT = 2.5Gb on cat 5e or better to 100m, 5Gb on Cat 6 or better at 100m, 10Gb on cat 6A or better to 100m. Depending on cable quality you might get 5Gb on cat 5e and 10Gb on cat 6, no guarantees. So, the “cat 7” connectors you bought on Amazon are BS because as you see from the information above, cat 7 does not support RJ45 connectors. That’s a fact. So why can cat 8 be used on RJ45 in addition to the other connectors I mentioned? It political as most Standardisation is. The US (ANSI/TIA TR 42.7 committee) never adopted cat 7 or 7A because some companies refused to move away from theRJ45 for fear that users would not support a solution that was not backward compatible. The ISO/IEC SC25/WG3 committee did ratify 7/7A components. Terminated links are called Class F and Class FA respectively. With Cat 8 we had the same concerns in the US so two grades were created, 8.1 and 8.2. The transmission specifications are identical but it much easier to achieve with the non-RJ45 connectors. I hope this helps and I’m happy to discuss via comments or privately if anyone has questions.
Great video, thanks a lot. I just equipped my new home with 23 Cat8 cables across the entire building, because I do not want to ever touch this installation again. So this should last for the next decades and for me the invest was worth it. Soon, the Cat8 keystones will be installed on both ends.
Great video. One slight clarification. The larger AWG wire for Cat 8 is not for allowing more data transmission through due to surface area. It is easier for the wire manufacturer to control the twisting of the wire pairs in a more precise way to reduce the crosstalk. The goal on each successive option is to operate at higher frequencies and reduce more crosstalk which is beyond the scope of this discussion. That is what allows greater transmission speed.
Sounds like the best future proofing is to also run blue ‘smurf’ tube everywhere so you can eventually pull the thinner, cheaper cable that will make Cat 8 obsolete - whatever THAT is.
If you need more than 10 G you just use fiber instead. You can have 40 or 100 G with cheap QSFP(+) modules. So just use cat 6a for copper connectivity, anything better is useless because, fiber.
that's kind of what i've been thinking about. a fusion splicer is NOT needed to terminate fiber OM3/OM4 if you get a kit or the right stuff, just make sure to measure twice and cut one and i guess you could just pull it on the wall along with 6A, 5e and RG6 if you wanted the full buffet.
@@cdoublejj You look around OM3 and OM4 can be manufactured to a specific length, its not even expensive to buy, in total spent less than £1000 to fiber the whole house (9 rooms plus 2 out rooms), 10 gig to every room (40 gig to office) All the cables made to measure, a switch "borrowed" from work job done.
Well actually for big data center you want to use copper as much as possible! Copper is always faster than fiber in short runs. Cat 8 support 40 and 100 Gig-E! Since Fibers always introduce latency and the more you have fiber the more you introduce latency, in the end, it adds up. But agree with you if you don't have hundreds of transactional server I would go with fiber. Each datacenter have to go through an evaluation of its needs.
@@NMETSGChan yes short runs most definitely but it seems the critical runs lately are distance and further away from the data centers. I’m shocked they are not making copper runs greater for distance.
I had to run a ethernet cables on the roof of a high power radio tower building, Cat 5E UTP couldn't work well and was trying to link up at 10mbps, but Cat 5e STP (shielded) worked fine at gigabit speeds, even at high 100MHz noise level. So to me cat 8 is for very specific uses at higher speeds, and I might as well use fiber at that point.
We will start to come full circle and hit Thinnet and finishing with Thicknet cabling. :) I have pulled all, and literally pulled on thinnet attached to Cat5 for ceiling run replacement, lol.
Cat8 is almost silly, its obsolete to fiber in price, distance and speed. Perhaps more practical for just patching since in that use case it would be quicker to install than splicing fiber. That being said for the utter majority of homes, small and medium business in the world that kind of available bandwidth for most of the runs they have would never be saturated. Or by the time it has a real practical use case it would have already been superseded by another available technology. Ive been installing for over a decade(Since 10bt token ring hubs etc) and I still recommend Cat5e for the majority of people, cat 6a for some of the backbone/CPE runs. Especially in residential applications its completely pointless.
Certainly agree that CAT 8 is a bit of waste, but there many out there including me that run 10G networks that need 6a or 7 for the longer runs. Thanks for the input.
@@TheRickJames Here where i live all new buildings has to have a fiber and Cat6 installed. Fiber is not usually used, the isp´s are using a fiber router and use the cat6's to split the internet to houses. But you CAN buy a fiber link if you really want to, The ISP will just use 2 fiber-Cat6 couplers one on the panel side, and one in house. its funny when i see it.
Cat 7 is not recognized by TIA/EIA and thus is NOT a standard in the United States. Cat 6 was ratified the same year Cat 7 was proposed and rejected. Cat 8 however is a recognized standard by TIA/EIA.
@@scythelord yep, 7 never became an official standard AFAIK. Cat 6A was ratified in 2009 if my memory is correct, and I'm pretty sure it's a TIA/EIA standard so it's industry supported as well. Cat 6A and 8 have their place and use, but IMO they are extremely specialized and very very few people need the performance and abilities these standards offer.
@@ChristopherGoggans I have no idea why anyone would want to deal with Cat7 or Cat8. They are a total pain to deal with and fiber is better in just about every way now.
Assuming you have 1GbE networking in your house and with that speed, you will not gain anything. This is mainly for 10GbE internal networking. Thanks for the question.
Man, if you are running inside of walls, use the best cables available. The labor costs of changing it later (or retrofitting it now) are way higher than the incremental cost of the cables and parts.
It would be helpful if towards the beginning of the video, you specified (labeled) which cable was what color. Blue = x, Yellow = y. I spent alot of time early in the video guessing which cable was which. Great information tho. Well explained.
Aren't we starting to lose the cost benefit of copper over fiber with the increased copper mass of these cables? Even factoring in the cost of 10G SFPs it looks like a fiber would be cheaper for a 30 meter run.
Cat 8 is supposed to be compatible with 40G over copper (I don't know if the standard is ratified, as I have not seen any RJ45-compatible hardware faster than 10G). That said, cost of fiber optic networks is decreasing. Even when you factor in cost of transceivers, that's rough to RJ45. You can run like 6 times more connections trough same space thanks to fiber being so slim. At this point I can see only one downside of fiber optics - if you need custom length you need some pretty expensive tools. For anything shorter than 10m you can go to copper DACs, which are usually on par with RJ45 cost wise. Then, on both SFP, QSFP and OSFP you can run 25, 40, 50 (now on SFP thanks to SFP56 standard), 100, 200, 400 and now 800 Gb. My company recently installed couple of 400G switches and seeing 400 to 8x SFP56 octopus breakout cable is wild. I've never seen Cat8 deployed anywhere outside a research lab, but Cat 7 is kind of popular in high EMI machines as internal wiring and communication between different modules, where galvanic separation is not required.
5:00 that is not specific to CAT8 though, you can get the exact same keystone for Cat 6 as well. It's what we have been using even since CAT6 became available. Entirely depends on the manufacturer of the keystone module. Also I strongly advise against putting a plug on an "installation cable" (in Europe this is considered to be a botched job), these cables are meant to be terminated with a keystone module and then left alone inside your rack. Reason being the solid wires inside these cables break rather easily when bent/twisted/manipulated frequently and that leads to all sorts of "fun" connection issues.
I've installed "Cat 5e" CCA UTP cables about 8 years ago because it was cheapest. Now i'm replacing all of them with dual branded cat 6A U/FTP cable and shielded keystone modules everywhere, except for the IP cameras, those are Cat 5e FTP (Cu). I remember arguing with someone about 2 years ago about cat 7 vs cat 8. I said "there is no cat 8, you must probably mean cat 7". I was wrong, so it seems?
What about different Connectors like ARJ45 or TERA - I have not seen Network Switches with these sort of Connector Types so far - although I was told there are a few?
I don't think TERA will ever become popular, especially since the standard is already 17 years old and still not used. The mian reason is compatibility. On the other hand ARJ45 looks promising, but looking at how it works, it seems like that connector will require support from the switch on both sides to work, and it will waste 4 wires in the cable, so I doubt it will happen. To be hones I don't think any new standards will appear, since we are slowly getting to the point where fiber optic devices are getting affordable. And the advantages of FO over copper are just too big. I think copper network wires will disapear before we will get consumer available 1 Tb/s internet connections.
I don't know why youtube decided that this should be in my recommended, but there is one thing I wonder and that is about the copper tape at 7:20. I know from personal experience that the adhesive side of aluminum tape is not conductive (I made a faraday cage inside a wooden box with alu tape). That is why I wonder if copper tape really makes contact with the ground wire or if the crimping from the locking boot is enough to push the glue away to make a firm connection to ground.
Seeing the pricing you've found is very interesting! Here in Canada, the pricing I can find lines up with yours for cat6 and cat6a, but cat 7 doubles it and is much closer to the price of cat8 than cat6a!
I used to run £1m rollouts of hardware including LAN and internet, we discovered that making the cables by hand was inferior to factory machine made cables, and they lasted only about 2 years before the performance started to drop off. Once we started buying custom factory made cables we got far less LAN issues.
nice video, hopefully CAT7 and 10G ethernet is gonna start to become the norm more and more but i dont see yet how anyone will need 40G in their home network anytime soon.
Agreed, but ive also never met someone that could fully saturate Cat6a even in the home, aside from a rare enterprise 10g or 2g bonded connection form the ISP, and in that case even the cable is installed by the ISP from the Modem to the Router. I have full fiber gigabit internet in a large overkill network in my home nd I still run Cat5e because no single appliance/end user will be saturating a full gigabit even... And I have servers, 4k cameras etc...
Cat7 is not needed for 10G. It only needs Cat6 or Cat6a depending on cable length. More than 55 meters needs 6A, and the vast majority of home network installations won't even come close to that.
Im doing Cat 6a regularly these days, its cheap and easy, and will be viable for a long time. Just pains me when i come back to panel and the user is using cheapest cat5 patches they can find to connect it all :D
I wish you just use metrics system, you confusing the heck out of me.... either way, great video, didnt need that crimping tutorial but I appreciate the feedback with the difference between the cable.
It's been probably 20 years since I terminated any Cat 5 cables which were not really that hard. I'm glad I retired from the business, because I can't imagine the patience need to terminate these Cat 7 & 8 cables. Good grief. They must be 10 times as expensive as the old Cat 5 cables I used.
3 года назад+2
Cat 7 & 8 are extremely rare, it's easier (and cheaper) use fiber optics
I remember running and terminating the IBM Type 1 cable for 16mb Token Ring. What a PIA that was. Some Missouri government offices are still wired with it. My Son worked in one. I had to laugh when I saw it.
I only use field termination plugs, much better for shielding. The wires get unshielded at both ends if you use a typical RJ45, that’s were a lot of the interference will happen.
Cat5e carry GE(1Gbps) and another hand it is pointless to run 10G at copper because fiber is cheaper, more robust, more future proof,offer longer distance, needs less energy etc. At 10Gbps speed is is just better almos every thing. Sadly it looks like motherboards will provide copper ethernet. So only point to use cat6a is support 10G for cheap desktop motherboards. Cat6 is just pointless at every aspect.
Fiber isn't necessarily cheaper than Cat6a for 10g because of the end equipment cost, oversized runs, spicing etc. But fiber is definitely more cost effective than Cat7 or Cat8. I think Cat8 especially is intended for patching rather than end equipment. A typical use case would be, bonded fiber to the Router, Fiber to the main MDF 40g Switch, SFP and/or Cat7/8 between the switches and patching, Cat6a to the end users.
Cat6 can handle 10G up to 55 meters, and the vast majority of home installations won't have runs longer than that. Cat6a is only needed for 10G runs longer than that, can Cat7 is never needed, period.
Why he couldn’t test the cable - the testers are not set up for Cat 7/8. These are theoretical categories. The EIA/TIA doesn’t really have much to say about this OM3 and OM4 Fiber will handle 10GB to 300m (984’) and 550m (1804’) respectively. Also, Fiber is cheaper than these silly so-called Cat 7/8.1/8.2 useless overpriced cables. You can purchase Category 6 Enhanced cable which tests to 600Mhz so why would anyone do this? Category 6A already meets 10G standards for short distances and testers exist which can certify, so once again, what is the point of Cat 7/8 other than to enrich companies like Siemons?? Real world applications for this are severely limited. Besides, who is going to buy switch gear and network cards and other infrastructure (patch panels, etc.) for a non-standard interface? This is practically useless for 99.9% of network installations.
@@gordonlawrence1448 en.wikipedia.org/wiki/Category_3_cable "Category 3 cable...is an unshielded twisted pair (UTP) cable used in telephone wiring... designed to reliably carry data up to 10 Mbps." And though the building was run using CAT5 cables each one was split 4 ways and each jack only had a single pair of wires terminated to it.
If you own your house and plan on keeping it = CAT 8 If you rent or may sell in the next decade = CAT6A unless you need VOIP, then CAT7 else CAT6. Done.
I have yet to see applications in Industry were that kind of data throughput is necessary on a machine control Network. We install cable all day long, most customers just want old 5e. Nobody cares if they're files take another 10 seconds to move. If I was running high definition video somewhere maybe but that's about it. So lets save some money! Nomore then cat 6. Cost is really high over cat6. Also high-speed Wireless is kicking their butt but it comes to speed. We can't use interference, fear-mongering for the justification for upgrading cables continuously. The only place I could ever see it truly being used would be server to server in the same room. We run dedicated fiber across the plants, to other servers. Why do we need this???
Agreed, that was my point too. Also as an installer I currently still recommend Cat5e because its the best fit for most use cases. I would also go full Fiber before I poked at that Cat8 headache and its cheaper. I look at Cat7 and Cat8 as more of a switch to switch and maybe some patch cables for 40/10g switches. Fiber, SFP etc kind of makes these obsolete. The most concern I get from people is around cameras, I have to explain that with the H.265 compression they use they cant even saturate a regular old Cat5 cable at 4k...
Can you do a explainer of single pair Ethernet? I only found out about it recently which is rather embarrassing given that I pride myself as a rabid follower of networking news.
I get a kick out of the fact that people call these RJ45 plugs and jacks. The RJ stands for Registered Jack from back in the days of Western Electric and the 45 was a designation for the cabling pin-out. The only thing these plugs have in common is the form factor and the pin-out. I guess RJ45 has just become part of the vernacular of our technology landscape. To provide some context there use to be, probably still exists out there somewhere the keyed RJ45, the RJ11, the RJ12, and the MMJ or Modified Modular Jack (used in old RS422 DecNet). Some of us old-timers were around before there was ubiquitous Ethernet and we had to also deal with some connectors like the IBM Type 1A used with MAUs in Token-Ring. We also were into vampires well before our kids with Twilight where we used Vampire Tapping tools for thick Ethernet. But going a bit further, who remember the old Token - Bus system ??? That was a real prize! The good old days of ArcNet and Banyan Vines. Kind of makes me nostalgic for the old 1200/2400 Baud Modems from US Robotics.
At home your fine with cat 5 or 6 since it outperforms most wifi you got after the router, and cost shit. If youbare going to use a high performance server m go for optics
I hope someone can give me some advise. I want to purchase cat 8 cables, but they have to be ran through a wall, so I would have to connect it to a wall plate. I can only find cat 6 wall plates on Amazon. If I used them, what would happen to the benefit of the cat 8 speed and so on?
I have links to all of it in the video description below the video in both videos. Cat 8 is very stiff when running through walls as it does not bend well. It can be done but it will be tougher. I would also consider using Cat 6A or 7 as it is much cheaper and a little easier to work with (ruclips.net/video/f2bILsfu8NM/видео.html). You will be able to get the 10GbE with 6A or 7.
All a typical home needs today to have Gig speed is cat 6. Devices capable of using bandwidth in excess of 100kb should have cat 6 patch cord ie. Apple TV.....
I'm interested in seeing the cost comparison between Cat7/Cat8 and fibre. In our network, we don't even bother with copper anymore for 10Gbit links. Costs for fibre and SFP+ adapters have really made the market competitive.
Agreed. Any time I'm looking at greater than 1G, I look to fiber, or DAC for shorter links. 10G-T is too expensive, and uses far too much power; 'tho it is getting better. Also, maybe I'm just too old... I don't see any need for 10G+ to my laptop, desktop, TV, etc.
The standard for cat 6a cable is 23 awg. I see a lot of vendors sale cat 6a cabkes in 26 and 28 awg. How will smaller gauge conductor affect performance?
Typically the smaller wire is multi-strand wire an$ is what they use for patch cables. Very hard to work with if you crimp your own but multi strand allows you to use smaller wire and get the same performance.
There's no need to use either of these. Cat7 doesn't even count as Ethernet cable. The specs skip right over it, as it's not needed for 10 gigabit and can't handle faster speeds like 25 and 40 gigabit. Those speeds need Cat8, but the hardware for running those speeds over Cat8 is far more expensive and power hungry than the hardware for running those speeds over fiber. Determining the right cable to use for an installation is easy. Don't care about futureproofing for 10 gigabit? Cat5e. Care about futureproofing for 10 gigabit, and all your cables will be under 55 meters long? Cat6. Care about futureproofing for 10 gigabit, and you'll have cables longer than 55 meters? Cat6a. But you can't just look at the category rating. Always get cable with pure copper conductors, never get cable made of CCA (copper-clad aluminum). Always get cable with solid conductors (rather than stranded) for installed cable, and always terminate installed cables with punch-down terminations rather than crimping plugs wherever possible. Patch cables (cables connecting devices to jacks) should be bought premade, as crimping plugs is much harder to do correctly than punch-downs.
Not really. Cat cable is both cheaper and generally better then moving to a full fat fiber backbone. A 10GbE fiber switch can cost easily over $40/port. Cat 7 and Cat 8 also aren't generally meant for every day runs -- Mostly because the standard requires solid core wires. If you're building a new house or commercial building it's 100% worth the extra cost to use Cat7 or Cat 8. You only have the drywall off once and running new lines after the fact is MUCH MORE costly then just upgrading the switches.
@@-Good4Y0u False. Cat 7 Standard is literally ISO 11801 Edition 2 Amendment 2 (2010) [F Channel] It isn't recognized by the TIA/EIA. -- But it *IS A STANDARD* Cat 8 however is also Ratified by under ANSI/TIA 568-C.2-1. And also an ISO standard.
Cat6a can run 10gig as long as the runs under 100m. Cat6a is easy to install anywhere. It's max bend radius is under 1.5 inches, meaning it can be safely run in a traditional framing system without bending it incorrectly. Cat7 is about 4 inches minimum bend radius, which is very hard to do in several spots in a home. Cat 8's minimum bend radius is over 6.5 inches. This would make it incredibly hard to impossible to wire something as simple as a wall outlet. Cat 7 and 8 arent intended to be run down walls to wall outlets. They are intended to plug things like routers, switches and servers together in a wide open room with cables chases.
If your fiber is carrying Ethernet, then it is an Ethernet cable. :-) As for cheaper, what would be great is to have a crystal ball and know where things will be in ten years.
Excellent video. Many thanks. Fully agree. 6a is the sweet spot as you can still use normal crimp RJ45 shielded termination. Cat 7 upwards just a pain! but I can see a use for datacentres. For residential and business building to building or server to a comms I always run armoured optical pairs with 2 pairs redundant. Better performance, and more future proof than copper. Also price difference to Cat8 is negligible when all things considered.
I only run cat 6 for the main wire between my modem router and switches. I still use cat 5e to go from my switch to the device. The only thing I kept the cat 6 to is my Xbox to make sure I get the best connection for my gaming.
We use cat5e for our gigabit ethernet run from basement to upstairs as the phone jack port all had cat5e runs and it was easier to turn the phone port to ethernet than run brand new cable through the walls. We get full speed through that cat 5e cable.... In fact, with newer technology, you can do 10g through cat 6a.... I have a network card which supports 10g through cat 6a.... Which is funny Cat 7 last i checked is not an official recognized standard... Cat 8 is however.... Both are useless and are not the future. The future is fiber because light is faster than copper.
I'd hate to do a whole wiring job with that stuff! I have found CAT7 to be useful when on shortish runs where interference from other sources (video, electrical...) cannot be avoided. Haven't worked with CAT8 yet. Both remind me of shielded token ring wiring, as it was pretty good about making it through factories with lots of high voltage equipment without loss.
@@MikeFaucher So was token ring! That was even better than those giant cables for S/36. Don't miss that at all. Of course we couldn't plug everything into Ethernet then, let alone wi-fi. One worker might have had a twinax for a terminal, another for a printer, token ring for a PC and a phone line and a fax line. Thanks for the video and your effort.
I’m reading on the product information page for bulk cat8 cable that most Ethernet ports on devices are not properly grounded. Do I need to ground the shielding somehow, or is it just overkill? Trying to search the Internet and not really getting a clear answer. e.g. product B07JQ2GSFQ on Amazon. Down in the description it states : "Important Note ***Routers, switches and modems with proper RJ45 port grounding recommended. Unshielded devices can generate an "Antenna Effect" and can cause network bottle-necking when used with dual shielded wires.***”
I was looking at patch cables today, and it seems that many companies are putting 26 AWG wire in their cat 6A patch cables, but using thicker wire in the cat 6 cable, which baffles me, because i often see like in your chart that you show 23 AWG wire for the 6A cabling. It seems like in patch cables, the more expensive 6a is using thinner wire!
Thinking of buying Cat 6A, and I'm confused with not finding Ethernet Cat 6a in stores, only Patch Cat 6a, and there isn't anything mentioned in specs of the speed, would patch work the same like ethernet Cat 6a?
Either will work, patch or bulk. The only difference is that patch is usually thinner as it is multi strand wire and usually can't be easier cut and re-terminated. Otherwise the performance is the same. If you are looking for bulk, there is an amazon link in the video description where you can buy a bulk roll. Thanks for the question.
@@MikeFaucher I need 2 cables for PC, and PS4, both connected to router, and with shipping Cat 6a would cost me just 5 Euros cheaper then 2 Cat 8 cables from Wish, what would you suggest, is Cat 8 worth those 5 Euros then? Not so much of a difference in money, but in quality? Both are S/FTP
Depends on the environment honestly. Fiber is immune to EMI, while even shielded twisted pair connections are still susceptible to interference. I do agree for the most part though. I would prefer maybe Cat 6a myself.
@@zoli34516 Interference is not important to the digital connection. CAT 7 and CAT 8 are used for gigabyte connections where the range is already limited. At the same time, the price of optical gigabit modules and media converters is cheap. Optical cable is sold terminated for any length - from 0.5m. Optics today trite hopes because of simplicity. Each cable has its own application. In the office, a twisted pair is probably better. Until the switch. Next is the optics. If you are a "heavy client" or a server, then definitely optics. Twisted pair, on the other hand, is easier to repair. There is no need for special tools. It is necessary to proceed from the scope of application.
Only for POE+, even then you could see a significant voltage drop over certain distances. Especially in use with balanced wattage applications, a larger conductor will hurt at a certain point. I think Cat6a is actually the sweet spot for this as far as carrying power is concerned.
Here, in Eastern Europe I'm lucky to have a 1 Gbps connection. Most of the people has slower connection. I have put a 25 meter long Cat 6 cable in the wall. We will not have 40 Gbps anytime soon. And we don't really need it anyway.
The cool thing about these things isn't just about download speeds, but file sharing among local area networks. Especially for youtube channels like Linus Tech Tips, where they use 8k video. A 40 Gbps connection would up their file sharing speed by 4x. Considering they're using 10 Gbps, and still maxing out the bandwidth on those connections.
@@Valentin119 yeah you'd be amazed just how annoying it is to be stuck on 1Gbps for local stuff once you get used to 10, 20, 40Gbps. I have two servers that share large VM disk and and pass on the whole X session over ssh. It would be a pain to manage them over 1Gbps, instead I bought some "old" HP 10Gbps dual port NICs from ebay and sat them up in aggregated mode to get the 20Gbps full duplex (or like the marketing would say 40Gbps) Before that I was actually facing the issue that the router would be the bottle neck and all the trafic would be caped at 500Mbps because it had to send 500Mbps up and down to each server making it "1Gbps" but not really. Like Zorro I'm lucky to have 1Gbps internet, but I wish my ISP would give me access to 10Gbps, not just for blazing fast por.... "creative content" but for actually start to migrate some of my network over to local data centers around the city, as of right now it's just not worth spending money on external servers if I'd be limiting myself to 1Gbps. it's fast for sure, but not really fast enough for really heavy data (as seen from Linux Tech Tips)... but then again it wouldn't be 30 dollars (299NOK) a month either :D
@@svampebob007 I'm only sitting at 275Mbps, it is plenty for my internet needs. My wife intends to do video editing, and doing youtube stuff for fun, and I want to create a mass storage server running a kind of raid variant. Not settled on which type to run yet. But something like these Cat 8 cables, or similar maybe 6a, is what I would like to speed of local data transfers to and from that mass storage. After I save up some money, I would eventually like to setup a mini home server, and network station, instead of needing to rely on my ISP's supplied cable modem.
@@Valentin119 TL;DR I'd recommend you take a look at SFP instead of RJ45. There's a lot of "old" discontinued server hardware on ebay that you can get for cheap. when I was looking at 10Gbps upgrade I saw the Asus 10Gbps Ethernet card and it cost 140USD for one single card, without cables included... ........................................................... Buying something like: 2xHP NC523FP with two 3M DAC (cable) = 85aus each so around 121USD for the whole thing that can do 20Gbps up and down. that's what I got and the only downside that it's only 3 meters cable (max 5M on DAC)... but both servers are located 2µm from each other :P I'm considering building an outside storage box for the servers (kinda like they did on Linus Tech Tips with their outside water loop) You can then go with fiber you can still get the NC523 or a similar dual 10Gbps NIC (some even go up to dual 40Gbps for cheap) and for connectivity you'll need the HP Blade System c-Class 10Gb (16USD) adapter and 30M Outdoor Field Fiber Patch Cord (56USD) The downside is that the adapters are kinda specific so you'll need to check the compatibility, and the cables are on the price of cat7-cat8 for 30M but those outdoor fiber patch cord come with a metal shield so it's easier to not break the fiber glass, you can go all the way up to 100M with fiber... but then it get's really freaking expensive for the adapters and quality cables... I trust eBay to sell medium range products, but if I was to spend more money I would be cautious about the actual quality of those fibers anything bellow 30M is pretty standard. Anyway good luck on your future project, relying on the ISP do give you a decent modem is the stupidest thing we do before investing in a good home network :)
@@svampebob007 Thanks for all the information! I'll have to keep that in mind! I am still in the process of obtaining all my certifications, currently working on my Networking from cisco and Comptia, so I am learning a whole bunch of stuff I never even knew about, glad I put off the project now, seeming that I definitely have more knowledge than I did back then, definitely would've done it wrong without knowing what I do now!
I've only been retired five years and there are three new cable types. We weren't getting most requests for Cat.5E. Only a few Cat 6. This is mostly customer generated as to cable type. Most of them have equipment they won't be replacing soon. If they were moving into a building that they're buying and doing major refurbishment I'd suggest going to the highest type emphasizing the cost of rewiring later at a higher cost. I talked a customer who was moving to wire his Unix system with unshielded twisted pair and adapters and patch panels so he could go to a PC system one day.He agreed but wasn't keen on it because his computer person said Unix would always be around. Well, his building was struck by lightning and everything was destroyed. His computer guru said he couldn't replace it so he had to go to a Windows based network. Thats when my advice was appreciated. They just removed the UNIX system reversed the connections to the patch panels and Digi Boards and the network was running.
Nice Video! I am working as an electrician here in Austria and in my company we only install cat.7 cables and use tool-less cat.6a or 7 keystones. If I recall correctly the bigger conductor size of cat.8 is because of the skin effect. High frequency currents only travel on the surface of the conductor !
@@AlejandroTaylorEscribano The Frequency is tied to the transmission speed Higher Frequencies give you higher Bandwidth. There are male and female , RJ45 keystones available Female are the ones you use in special wall sockets that come empty so the keystones act as receptacles
Lol, there is no such thing as Cat-7. That's because category cables are governed by the TIA/ANSI standards organization. Back in the mid-2000's the TIA was about to ratify Cat-7, it was the final draft. Then suddenly another standards org from Europe called ISO took the final TIA draft, and published the standard itself with a few minor changes. It was a dramatic coup d'etat, they were actually trying todo a hostile take over a cable spec from its standards body. Well anyways, nobody recognizes Cat-7, because it was not legitimate, because the TIA still was the governing standards body for category cable. So TIA renamed their standard as Cat-6a, and enumerated Cat-8 & Cat-8a so they could not be leapfrogged again. The only network equipment company that accepted the ISO Cat-7 spec was Siemens, a European company. The rest of the world simply ignored Cat-7, and so should you... Because it doesn't exist, it's not a TIA spec.
Thanks and you are correct however though not ratified MFGs are selling it as cat 7 and most have consistent specs. To ignore it would not be fair to people looking into cabling. Thanks for the expertise and sharing it.
@@MikeFaucher I disagree, both Cat-6a and the so-called "Cat-7" have AWG-23 wires, which go into (and beyond) the 750Mhz band. One spec says 500, the other 600.... But both cables are electrically equivalent in reality. So please, just ignore cat-7
@@MikeFaucher btw, not trying to be contentious. Sry about that. Love your videos! 👍 For more context, the TIA wanted to take a more conservative approach, they were more focused on the idea of 100 meter cable length guarantee, so they wanted to balance wire gauge vs insulation/shielding, with a bias towards being as minimal as possible. These topics were debated during the draft process, and some entities didn't like the chosen outcome. The ISO observing this decided to intervene. This is a gross over-simplification, and the drama doesn't really matter. The prevailing point is cat-6a cables are for all intentions & purposes... Equivalent to cat-7, but the later is not a legitimate standard. The only difference that matters is the QA process, where cat-7 must maintain 600 MHz modulation, cat-6a tests at minimum 500 MHz. That said, in reality the various cable testers use 750 MHz, and get to say the cable exceeds the spec. 23 awg easily meets that spec, but attenuation over distance degrades, so shielding... The ISO spec was less concerned about distance, presumably fiber filed that space, so they specified just enough insulation to handle a row of racks in the data center, about ~30 meters, and we get cheaper cables with a nominal bump in modulation.
Thanks for the insight as you obviously have a lot of knowledge so the input is appreciated. No need to apologize as I completely understand and agree with what you are say that it is not a certified product. This is a classic case of MFG building ahead of ratification as they did with WiFI 5 and 6 and never pulled the product before approval. Anyway, thanks for the input and thanks for watching.
I only have 1 ethernet cable in my home and it's a Flat Cat7 that goes from the modem to my pc (aorund 15meters). To connect my server room to my nework i have used an optic fiber cable (around 30 meters) and with it i don't have inteference problem and thick shields and thick cables.
Couple of questions: do you think the connectors on aliexpress are really cat8. And does it slow that much down that you cant get the rated speeds if you use real cat8 cable and cat6/6a connectors? Do you know some make cables that are for sure cat7a+ / cat8? Because i think there are a lot of fake/outside specs cables. And the last question, i cant find any stranded cat7a+ / cat8 cable, does that mean all are solid, so from wall socket to pc that needs to be also solid?
Its not RJ-45 Connector its a 8P8C modular connector RJ-45 is registered Jack 45 used in telephone modem connections where pin 4 and 5 are tip and ring and 7 and 8 are connected to a resistor that indicates the signal loss from the central office to the Modem. It would be good if the bad naming stopped being perpetuated by instructional materials. Like many other things people uneducated it the actual facts picked up the name and used it for a different purpose; then it gets added incorrectly into the common lexicon by marketing people and volai suddenly it starts to be used incorrectly by even less educated people
The only real difference between these two are the green and orange pairs for backward compatibility with older phone systems. Most patch cables that are bought today are "B" and this is the standard for the US, however in Europe I believe they mostly use "A". As long as it is uniform in your network, it really does not matter but most new installs are using "B".
I wouldn't unless you needed RJ45/Copper to connect which is more flexible. Fiber is better for longer runs and is very cost effective as long as you buy pre-made cables.
@@MikeFaucher do you know the coaxial cable specs that are required for docsis 4.0 ? im guessing we also need to change the cable due to frequency increase to 1.8ghz in docsis 4.0
@ 2:34 in the video, a lot of the CAT6a i've bought in the past 2 or so years looks nearly if not exactly identical to that CAT7, so long as it's SFTP or FSTP aka fully shielded twisted pair.
@@MikeFaucher d seem exceeding spec is not issue, at least with some 6a which i think some is even 23 gauge. but, cat 7 REQUIRES these features. 8 seems to be a true upgrade. mostly best for data center. or equipped to deal with PoE++ which can push 75 watts of power minus overhead. EDIT: also 25gbit on 6a through 8 would be interesting to see
Many of the patch cables use multi-stranded wire with is much thinner so the overall is much thinner. The bulk wire in this video uses thicker solid wire.
@@MikeFaucher It's not certified by any major certification organization, rather it was REJECTED which means its not a standard and should be stated as such. By including it as a standard in what is an 'educational ' video its giving credence to the idea that it IS a standard. Also T568A is the better of the two wiring schemes because its required for any US government project and is backwards compatible . T568B can't be used on a government job nor is it as backwards compatible. There is no downside to using T568A but there is to T568B.
yes there is a difference 8 is higher then 7 that's why cat 8 is different then cat 7 you should use it cause it's a higher number and that's why you should be using it lol
It's three years later, are there even 40 Gb/s RJ45 switches / network cards to make use of CAT 8? I feel like doing singlemode fibre for 10+ Gb/s is way more flexible. I mean, you can push 25 Gb/s or even faster trough fibre for many tens of miles / kilometres. And tbf, I don't believe I'm saying this, 10 Gb/s for in-house (home use) copper cabling is enough, for faster stuff, use fibre instead. So just use CAT 6A instead of the more expensive CAT 8???

Just a job.. here in Russia we use only Cat 5. Speeds over 1G are only reachable with fiber-optic. Cat 6-8 are not acceptable because of money/speed proportion.
Funny how we went from thick coax cables to thin twisted pair cables and back to thick cabling again.
Just like how we have returned to vinyl records and paper grocery bags.
The good old twinax and IBM Type1 cables - how I don't miss those.
Who would have expected (back in the days of the 80's cat3-4) to be running 2GHz over twisted pair -it was generally accepted such signals were within the relm of coax.
I did Cat 8 because all my walls were torn out during a renovation. I figured there’s no easier time to just completely future proof my home network. Yes it was extremely expensive with the keystones and field terminations but a $2000 investment beats the hell out of having to redo it at somepoint.
I agree completely. Sounds great and thanks for sharing. Good luck with it.
$2000 ?? I bought 25 meters of cat 8 cable with 3 cat 8 connectors for each side and additional stuff for € 100.
Personally, I would do an OS2 fibre to be futureproof (>200gbe)...
Home run ENT/Smurf tube ftw. The future is whenever you feel like fishing it.
Damn today I learned there is a Cat 8.
I'm still using Cat5e and 6 at my house, which is fine.
Things sure escalate quickly
Cat5e will still be fine for a long time, as long as you don't own a palace,10G family networking can totally run in short distance with cat5e.
Same, federal ISP i'ms working for still using 5e for apartments even for gigabit ethernet
Cat 5 was the latest tech when I did Cisco networking in high school and college and 5e came out shortly after. I wired my home with cat 5 and 5e and did a few small offices where I was doing build outs as I was a pro painter and did framing, drywall, and electrical....pretty much everything for typical commercial buildings. Things change fast and I have only had to do a few patch cables in the last 10 years or so.
There are more than 8 CATS outside my place. Maybe CATS 9-15.
Folks, please don’t believe everything you see on Amazon. I work on both the US and global standards development organizations that develops all of the cabling category standards and I’m going to provide a few facts about the different categories of cables and their constructions/specifications.
UTP=no shielding at all.
F/UTP=unshielded pairs with an overall foil shield.
Sc/UTP=unshielded pairs with a screened (braided) shield.
F/FTP=shielded pairs with overall foil shielded.
Sc/FTP=shielded pairs with screened shield.
Cat5e through cat6 can be constructed with any of the above depending on the users requirements.
Cat7 and up must be Sc/FTP because of the extended frequency range. The shielded pairs mitigate internal crosstalk and the screen mitigates alien crosstalk between cables in a bundle.
Cat5e=100 MHz, 1Gb/s at 100m, any connector style.
Cat6= 250MHz, 1Gb/s at 100m, 10Gb/s at 55m, any connector style.
Cat6A= 500 MHz, 10Gb/s at 100m, any connector style.
Cat7= 600 MHz, 10Gb/s at 100m, only EC7, GG45 or TERA connectors (google them), RJ45 not supported.
CatA= 1000 MHz, 10Gb/s at 100m, 25Gb/s at 50m, only EC7, GG45 or TERA connectors, RJ45 not supported.
Cat8.1= 2000MHz, 10Gb/s at 100m, 40 Gb/s at 30m, any connector style.
Cat8.2=2000 MHz, 10Gb/s at 100m, only EC7, GG45 or TERA connectors, RJ45 not supported.
Multigig/NBaseT = 2.5Gb on cat 5e or better to 100m, 5Gb on Cat 6 or better at 100m, 10Gb on cat 6A or better to 100m. Depending on cable quality you might get 5Gb on cat 5e and 10Gb on cat 6, no guarantees.
So, the “cat 7” connectors you bought on Amazon are BS because as you see from the information above, cat 7 does not support RJ45 connectors. That’s a fact. So why can cat 8 be used on RJ45 in addition to the other connectors I mentioned? It political as most Standardisation is. The US (ANSI/TIA TR 42.7 committee) never adopted cat 7 or 7A because some companies refused to move away from theRJ45 for fear that users would not support a solution that was not backward compatible. The ISO/IEC SC25/WG3 committee did ratify 7/7A components. Terminated links are called Class F and Class FA respectively.
With Cat 8 we had the same concerns in the US so two grades were created, 8.1 and 8.2. The transmission specifications are identical but it much easier to achieve with the non-RJ45 connectors.
I hope this helps and I’m happy to discuss via comments or privately if anyone has questions.
Thanks for providing the extra detail.
@@MikeFaucher No problem!
Thanks for this info noted on this!
What is cat 6e?
Great video, thanks a lot. I just equipped my new home with 23 Cat8 cables across the entire building, because I do not want to ever touch this installation again. So this should last for the next decades and for me the invest was worth it. Soon, the Cat8 keystones will be installed on both ends.
Awesome. That is what I call future proofing. Thanks for sharing.
@@MikeFaucher nothing personal but that is not future proofing that`s wasting money. Cat 6 is more than enough for residential and small businesses
For our new house we ran Cat6, Cat6a, Cat7, and OM3/OM4 fiber. :-)
Cat7 is sufficient enough.
@@momchil_v Can you predict the future. His house will last at least 30 years. Do you know what kinds of data speeds will be used in the year 2050?
Great video. One slight clarification. The larger AWG wire for Cat 8 is not for allowing more data transmission through due to surface area. It is easier for the wire manufacturer to control the twisting of the wire pairs in a more precise way to reduce the crosstalk.
The goal on each successive option is to operate at higher frequencies and reduce more crosstalk which is beyond the scope of this discussion. That is what allows greater transmission speed.
Thanks for the explanation and feedback.
Sounds like the best future proofing is to also run blue ‘smurf’ tube everywhere so you can eventually pull the thinner, cheaper cable that will make Cat 8 obsolete - whatever THAT is.
If you need more than 10 G you just use fiber instead. You can have 40 or 100 G with cheap QSFP(+) modules. So just use cat 6a for copper connectivity, anything better is useless because, fiber.
that's kind of what i've been thinking about. a fusion splicer is NOT needed to terminate fiber OM3/OM4 if you get a kit or the right stuff, just make sure to measure twice and cut one and i guess you could just pull it on the wall along with 6A, 5e and RG6 if you wanted the full buffet.
@@cdoublejj You look around OM3 and OM4 can be manufactured to a specific length, its not even expensive to buy, in total spent less than £1000 to fiber the whole house (9 rooms plus 2 out rooms), 10 gig to every room (40 gig to office) All the cables made to measure, a switch "borrowed" from work job done.
I agree. Distance seems to be the problem here and they have yet to fix that with copper. Fiber it is.
Well actually for big data center you want to use copper as much as possible! Copper is always faster than fiber in short runs. Cat 8 support 40 and 100 Gig-E!
Since Fibers always introduce latency and the more you have fiber the more you introduce latency, in the end, it adds up.
But agree with you if you don't have hundreds of transactional server I would go with fiber.
Each datacenter have to go through an evaluation of its needs.
@@NMETSGChan yes short runs most definitely but it seems the critical runs lately are distance and further away from the data centers. I’m shocked they are not making copper runs greater for distance.
hopefully the cat only has 9 lives.
Cat 8, when you need to run a drop through an 'always on' 70's microwave display.
I had to run a ethernet cables on the roof of a high power radio tower building, Cat 5E UTP couldn't work well and was trying to link up at 10mbps, but Cat 5e STP (shielded) worked fine at gigabit speeds, even at high 100MHz noise level. So to me cat 8 is for very specific uses at higher speeds, and I might as well use fiber at that point.
Interesting I purchased Cat7 500 m and payed 100 euro for it only downside, cable is orange.
CAT9 will be just a stiff rod of copper.
We will start to come full circle and hit Thinnet and finishing with Thicknet cabling. :) I have pulled all, and literally pulled on thinnet attached to Cat5 for ceiling run replacement, lol.
Cat8 is almost silly, its obsolete to fiber in price, distance and speed. Perhaps more practical for just patching since in that use case it would be quicker to install than splicing fiber. That being said for the utter majority of homes, small and medium business in the world that kind of available bandwidth for most of the runs they have would never be saturated. Or by the time it has a real practical use case it would have already been superseded by another available technology. Ive been installing for over a decade(Since 10bt token ring hubs etc) and I still recommend Cat5e for the majority of people, cat 6a for some of the backbone/CPE runs. Especially in residential applications its completely pointless.
Certainly agree that CAT 8 is a bit of waste, but there many out there including me that run 10G networks that need 6a or 7 for the longer runs. Thanks for the input.
@@TheRickJames Here where i live all new buildings has to have a fiber and Cat6 installed.

Cat 7 is not recognized by TIA/EIA and thus is NOT a standard in the United States. Cat 6 was ratified the same year Cat 7 was proposed and rejected. Cat 8 however is a recognized standard by TIA/EIA.
@@scythelord yep, 7 never became an official standard AFAIK. Cat 6A was ratified in 2009 if my memory is correct, and I'm pretty sure it's a TIA/EIA standard so it's industry supported as well.

@@ChristopherGoggans I have no idea why anyone would want to deal with Cat7 or Cat8. They are a total pain to deal with and fiber is better in just about every way now.

Assuming you have 1GbE networking in your house and with that speed, you will not gain anything. This is mainly for 10GbE internal networking. Thanks for the question.
Man, if you are running inside of walls, use the best cables available. The labor costs of changing it later (or retrofitting it now) are way higher than the incremental cost of the cables and parts.
Very true and good point.
It would be helpful if towards the beginning of the video, you specified (labeled) which cable was what color. Blue = x, Yellow = y. I spent alot of time early in the video guessing which cable was which. Great information tho. Well explained.
Great point. Thanks

@@dvwjr79 yellow is cat8
@@angistron thank you
And here I am happily running 10gige over old cat5, hand-crimped...with no issues. =)
Aren't we starting to lose the cost benefit of copper over fiber with the increased copper mass of these cables? Even factoring in the cost of 10G SFPs it looks like a fiber would be cheaper for a 30 meter run.
Good point.
Cat 8 is supposed to be compatible with 40G over copper (I don't know if the standard is ratified, as I have not seen any RJ45-compatible hardware faster than 10G). That said, cost of fiber optic networks is decreasing. Even when you factor in cost of transceivers, that's rough to RJ45. You can run like 6 times more connections trough same space thanks to fiber being so slim. At this point I can see only one downside of fiber optics - if you need custom length you need some pretty expensive tools. For anything shorter than 10m you can go to copper DACs, which are usually on par with RJ45 cost wise. Then, on both SFP, QSFP and OSFP you can run 25, 40, 50 (now on SFP thanks to SFP56 standard), 100, 200, 400 and now 800 Gb. My company recently installed couple of 400G switches and seeing 400 to 8x SFP56 octopus breakout cable is wild.
I've never seen Cat8 deployed anywhere outside a research lab, but Cat 7 is kind of popular in high EMI machines as internal wiring and communication between different modules, where galvanic separation is not required.
I think you called cat8 “cat7” a few times in the beginning. Maybe put a little note so you don’t have to redo the great video.

@@robertsteich7362 Yes it is. Thank you.
This guy is really into this reminds me of my teacher when he was showing us how to crimp these bad boys down
Thanks,
5:00 that is not specific to CAT8 though, you can get the exact same keystone for Cat 6 as well. It's what we have been using even since CAT6 became available. Entirely depends on the manufacturer of the keystone module.
Also I strongly advise against putting a plug on an "installation cable" (in Europe this is considered to be a botched job), these cables are meant to be terminated with a keystone module and then left alone inside your rack. Reason being the solid wires inside these cables break rather easily when bent/twisted/manipulated frequently and that leads to all sorts of "fun" connection issues.
Thanks for the input.
Do you have any examples of the advised method. A picture maybe?
Just keystones on both sides lol
With a patch panel in the rack
I've installed "Cat 5e" CCA UTP cables about 8 years ago because it was cheapest. Now i'm replacing all of them with dual branded cat 6A U/FTP cable and shielded keystone modules everywhere, except for the IP cameras, those are Cat 5e FTP (Cu).
I remember arguing with someone about 2 years ago about cat 7 vs cat 8. I said "there is no cat 8, you must probably mean cat 7". I was wrong, so it seems?
Just add, don't take, your Cat5e will support VOIP, may be 7 wont?
What about different Connectors like ARJ45 or TERA - I have not seen Network Switches with these sort of Connector Types so far - although I was told there are a few?
I don't think TERA will ever become popular, especially since the standard is already 17 years old and still not used.
The mian reason is compatibility.
On the other hand ARJ45 looks promising, but looking at how it works, it seems like that connector will require support from the switch on both sides to work,
and it will waste 4 wires in the cable, so I doubt it will happen.
To be hones I don't think any new standards will appear, since we are slowly getting to the point where fiber optic devices are getting affordable.
And the advantages of FO over copper are just too big.
I think copper network wires will disapear before we will get consumer available 1 Tb/s internet connections.
I don't know why youtube decided that this should be in my recommended, but there is one thing I wonder and that is about the copper tape at 7:20. I know from personal experience that the adhesive side of aluminum tape is not conductive (I made a faraday cage inside a wooden box with alu tape). That is why I wonder if copper tape really makes contact with the ground wire or if the crimping from the locking boot is enough to push the glue away to make a firm connection to ground.
Valid concern however this copper tape and adhesive do work and I did verify with an ohm meter that both were conductive. Thanks for the comment.
Should I upgrade my 56k modem?
Maybe Apple makes some in really pretty colors, probably $300 on sale.
I would downgrade to 28.8, much more reliable. 😀
Seeing the pricing you've found is very interesting! Here in Canada, the pricing I can find lines up with yours for cat6 and cat6a, but cat 7 doubles it and is much closer to the price of cat8 than cat6a!
Wow, that is steep. May not be as popular or available.
I used to run £1m rollouts of hardware including LAN and internet, we discovered that making the cables by hand was inferior to factory machine made cables, and they lasted only about 2 years before the performance started to drop off. Once we started buying custom factory made cables we got far less LAN issues.

Agreed, but ive also never met someone that could fully saturate Cat6a even in the home, aside from a rare enterprise 10g or 2g bonded connection form the ISP, and in that case even the cable is installed by the ISP from the Modem to the Router. I have full fiber gigabit internet in a large overkill network in my home nd I still run Cat5e because no single appliance/end user will be saturating a full gigabit even... And I have servers, 4k cameras etc...

Cat7 is not needed for 10G. It only needs Cat6 or Cat6a depending on cable length. More than 55 meters needs 6A, and the vast majority of home network installations won't even come close to that.
Im doing Cat 6a regularly these days, its cheap and easy, and will be viable for a long time. Just pains me when i come back to panel and the user is using cheapest cat5 patches they can find to connect it all :D
I wish you just use metrics system, you confusing the heck out of me.... either way, great video, didnt need that crimping tutorial but I appreciate the feedback with the difference between the cable.
It's been probably 20 years since I terminated any Cat 5 cables which were not really that hard. I'm glad I retired from the business, because I can't imagine the patience need to terminate these Cat 7 & 8 cables. Good grief. They must be 10 times as expensive as the old Cat 5 cables I used.
Cat 7 & 8 are extremely rare, it's easier (and cheaper) use fiber optics
I think I’ll go dust off that IBM Type 1a and just re-terminate it ....😉
I remember running and terminating the IBM Type 1 cable for 16mb Token Ring. What a PIA that was. Some Missouri government offices are still wired with it. My Son worked in one. I had to laugh when I saw it.
I only use field termination plugs, much better for shielding. The wires get unshielded at both ends if you use a typical RJ45, that’s were a lot of the interference will happen.
Thanks for you input!
Cat5e carry GE(1Gbps) and another hand it is pointless to run 10G at copper because fiber is cheaper, more robust, more future proof,offer longer distance, needs less energy etc. At 10Gbps speed is is just better almos every thing. Sadly it looks like motherboards will provide copper ethernet. So only point to use cat6a is support 10G for cheap desktop motherboards. Cat6 is just pointless at every aspect.
The one down side of fiber is no step down. Good point.
Fiber isn't necessarily cheaper than Cat6a for 10g because of the end equipment cost, oversized runs, spicing etc. But fiber is definitely more cost effective than Cat7 or Cat8. I think Cat8 especially is intended for patching rather than end equipment. A typical use case would be, bonded fiber to the Router, Fiber to the main MDF 40g Switch, SFP and/or Cat7/8 between the switches and patching, Cat6a to the end users.
Cat6 can handle 10G up to 55 meters, and the vast majority of home installations won't have runs longer than that. Cat6a is only needed for 10G runs longer than that, can Cat7 is never needed, period.
Why he couldn’t test the cable - the testers are not set up for Cat 7/8. These are theoretical categories. The EIA/TIA doesn’t really have much to say about this
OM3 and OM4 Fiber will handle 10GB to 300m (984’) and 550m (1804’) respectively. Also, Fiber is cheaper than these silly so-called Cat 7/8.1/8.2 useless overpriced cables.
You can purchase Category 6 Enhanced cable which tests to 600Mhz so why would anyone do this?
Category 6A already meets 10G standards for short distances and testers exist which can certify, so once again, what is the point of Cat 7/8 other than to enrich companies like Siemons??
Real world applications for this are severely limited. Besides, who is going to buy switch gear and network cards and other infrastructure (patch panels, etc.) for a non-standard interface? This is practically useless for 99.9% of network installations.
Agreed. Thanks for the input.
Can't see very well. You should zoom in more.
thanks. Will do next time.

And though the building was run using CAT5 cables each one was split 4 ways and each jack only had a single pair of wires terminated to it.
They could have added a screw-on instead of the ziptie to make it "nicer". I don't think the length would have matter anyway.
If you own your house and plan on keeping it = CAT 8
If you rent or may sell in the next decade = CAT6A unless you need VOIP, then CAT7
else CAT6.
Done.
Not a bad solution but just remember cat 8 is stiff and does not like to bend around corners. Thanks.
I have yet to see applications in Industry were that kind of data throughput is necessary on a machine control Network. We install cable all day long, most customers just want old 5e. Nobody cares if they're files take another 10 seconds to move. If I was running high definition video somewhere maybe but that's about it. So lets save some money! Nomore then cat 6. Cost is really high over cat6. Also high-speed Wireless is kicking their butt but it comes to speed. We can't use interference, fear-mongering for the justification for upgrading cables continuously. The only place I could ever see it truly being used would be server to server in the same room. We run dedicated fiber across the plants, to other servers. Why do we need this???
Everyone has different needs. Thanks for the feedback and comments
Agreed, that was my point too. Also as an installer I currently still recommend Cat5e because its the best fit for most use cases. I would also go full Fiber before I poked at that Cat8 headache and its cheaper. I look at Cat7 and Cat8 as more of a switch to switch and maybe some patch cables for 40/10g switches. Fiber, SFP etc kind of makes these obsolete. The most concern I get from people is around cameras, I have to explain that with the H.265 compression they use they cant even saturate a regular old Cat5 cable at 4k...
Can you do a explainer of single pair Ethernet? I only found out about it recently which is rather embarrassing given that I pride myself as a rabid follower of networking news.
I will put it on my.
I get a kick out of the fact that people call these RJ45 plugs and jacks. The RJ stands for Registered Jack from back in the days of Western Electric and the 45 was a designation for the cabling pin-out. The only thing these plugs have in common is the form factor and the pin-out. I guess RJ45 has just become part of the vernacular of our technology landscape. To provide some context there use to be, probably still exists out there somewhere the keyed RJ45, the RJ11, the RJ12, and the MMJ or Modified Modular Jack (used in old RS422 DecNet). Some of us old-timers were around before there was ubiquitous Ethernet and we had to also deal with some connectors like the IBM Type 1A used with MAUs in Token-Ring. We also were into vampires well before our kids with Twilight where we used Vampire Tapping tools for thick Ethernet. But going a bit further, who remember the old Token - Bus system ??? That was a real prize! The good old days of ArcNet and Banyan Vines. Kind of makes me nostalgic for the old 1200/2400 Baud Modems from US Robotics.
Thank you.
Q can i use Cat6a KeyStone Jacks with CAT7 to arrive the 40GBit in CAT7 Cables OR is there any technical Reason why not?
Technically your can. I have no way to verify that as I am in the process of collecting some 40G hardware.
At home your fine with cat 5 or 6 since it outperforms most wifi you got after the router, and cost shit. If youbare going to use a high performance server m go for optics
I hope someone can give me some advise. I want to purchase cat 8 cables, but they have to be ran through a wall, so I would have to connect it to a wall plate. I can only find cat 6 wall plates on Amazon. If I used them, what would happen to the benefit of the cat 8 speed and so on?
I have links to all of it in the video description below the video in both videos. Cat 8 is very stiff when running through walls as it does not bend well. It can be done but it will be tougher. I would also consider using Cat 6A or 7 as it is much cheaper and a little easier to work with (ruclips.net/video/f2bILsfu8NM/видео.html). You will be able to get the 10GbE with 6A or 7.
All a typical home needs today to have Gig speed is cat 6. Devices capable of using bandwidth in excess of 100kb should have cat 6 patch cord ie. Apple TV.....
I'm interested in seeing the cost comparison between Cat7/Cat8 and fibre.
In our network, we don't even bother with copper anymore for 10Gbit links. Costs for fibre and SFP+ adapters have really made the market competitive.
Agreed. Any time I'm looking at greater than 1G, I look to fiber, or DAC for shorter links. 10G-T is too expensive, and uses far too much power; 'tho it is getting better. Also, maybe I'm just too old... I don't see any need for 10G+ to my laptop, desktop, TV, etc.
Q which Network card with RJ45 Connector you know who is able to make 40GBit with RJ45?
ATTO and Mellanox just to name a couple but there are others.
The standard for cat 6a cable is 23 awg. I see a lot of vendors sale cat 6a cabkes in 26 and 28 awg. How will smaller gauge conductor affect performance?
Typically the smaller wire is multi-strand wire an$ is what they use for patch cables. Very hard to work with if you crimp your own but multi strand allows you to use smaller wire and get the same performance.
Looks like a nightmare to terminate. Had Cat 5e installed by myself at home last year. Could have gone Cat 6 but the cost does not justify it.
Nothing wrong with that if it works for your needs. Termination is not as bad as it looks. Shielding is a bit of a hassle.
There's no need to use either of these. Cat7 doesn't even count as Ethernet cable. The specs skip right over it, as it's not needed for 10 gigabit and can't handle faster speeds like 25 and 40 gigabit. Those speeds need Cat8, but the hardware for running those speeds over Cat8 is far more expensive and power hungry than the hardware for running those speeds over fiber. Determining the right cable to use for an installation is easy. Don't care about futureproofing for 10 gigabit? Cat5e. Care about futureproofing for 10 gigabit, and all your cables will be under 55 meters long? Cat6. Care about futureproofing for 10 gigabit, and you'll have cables longer than 55 meters? Cat6a. But you can't just look at the category rating. Always get cable with pure copper conductors, never get cable made of CCA (copper-clad aluminum). Always get cable with solid conductors (rather than stranded) for installed cable, and always terminate installed cables with punch-down terminations rather than crimping plugs wherever possible. Patch cables (cables connecting devices to jacks) should be bought premade, as crimping plugs is much harder to do correctly than punch-downs.
Thank you for the feedback. I appreciate it.
These standards seem pointless. Cat6a holds important ground, beyond that we need to move past copper
Not really. Cat cable is both cheaper and generally better then moving to a full fat fiber backbone. A 10GbE fiber switch can cost easily over $40/port.
Cat 7 and Cat 8 also aren't generally meant for every day runs -- Mostly because the standard requires solid core wires. If you're building a new house or commercial building it's 100% worth the extra cost to use Cat7 or Cat 8. You only have the drywall off once and running new lines after the fact is MUCH MORE costly then just upgrading the switches.
@@AgentLokVokun cat 7 is not a recognized standard
@@-Good4Y0u False. Cat 7 Standard is literally ISO 11801 Edition 2 Amendment 2 (2010) [F Channel]
It isn't recognized by the TIA/EIA. -- But it *IS A STANDARD*
Cat 8 however is also Ratified by under ANSI/TIA 568-C.2-1. And also an ISO standard.
Cat6a can run 10gig as long as the runs under 100m.
Cat6a is easy to install anywhere. It's max bend radius is under 1.5 inches, meaning it can be safely run in a traditional framing system without bending it incorrectly. Cat7 is about 4 inches minimum bend radius, which is very hard to do in several spots in a home. Cat 8's minimum bend radius is over 6.5 inches. This would make it incredibly hard to impossible to wire something as simple as a wall outlet.
Cat 7 and 8 arent intended to be run down walls to wall outlets. They are intended to plug things like routers, switches and servers together in a wide open room with cables chases.
@@discodench - I suppose someone in a pinch can fit the Cat 8 into a 90 degree jack.
Don't waste your money on Ethernet cables, switch to Fiber, it is cheaper and vastly better.
If your fiber is carrying Ethernet, then it is an Ethernet cable. :-) As for cheaper, what would be great is to have a crystal ball and know where things will be in ten years.
19:25 where you got this info, that CAT7 is able to make 40GBit
I found this in various MFG specs. 7A is rated at 50M.
Excellent video. Many thanks. Fully agree. 6a is the sweet spot as you can still use normal crimp RJ45 shielded termination. Cat 7 upwards just a pain! but I can see a use for datacentres.
For residential and business building to building or server to a comms I always run armoured optical pairs with 2 pairs redundant. Better performance, and more future proof than copper. Also price difference to Cat8 is negligible when all things considered.
Thanks for the feedback and the insight. It's appreciated.
Me who just using 5e😂
Thank you for the feedback. I appreciate it.
Honestly most people still use it. I use it for installing cameras and residential drops. I rarely see 6a or better.
I only run cat 6 for the main wire between my modem router and switches. I still use cat 5e to go from my switch to the device. The only thing I kept the cat 6 to is my Xbox to make sure I get the best connection for my gaming.
@@KevinBenecke - Hell you could probably get away with 100 mbit Cat3 for gaming.
We use cat5e for our gigabit ethernet run from basement to upstairs as the phone jack port all had cat5e runs and it was easier to turn the phone port to ethernet than run brand new cable through the walls. We get full speed through that cat 5e cable....
In fact, with newer technology, you can do 10g through cat 6a.... I have a network card which supports 10g through cat 6a.... Which is funny
Cat 7 last i checked is not an official recognized standard... Cat 8 is however.... Both are useless and are not the future. The future is fiber because light is faster than copper.
I'd hate to do a whole wiring job with that stuff!
I have found CAT7 to be useful when on shortish runs where interference from other sources (video, electrical...) cannot be avoided.
Haven't worked with CAT8 yet.
Both remind me of shielded token ring wiring, as it was pretty good about making it through factories with lots of high voltage equipment without loss.
Yeah it would be a lot of work.
@@MikeFaucher So was token ring! That was even better than those giant cables for S/36. Don't miss that at all. Of course we couldn't plug everything into Ethernet then, let alone wi-fi. One worker might have had a twinax for a terminal, another for a printer, token ring for a PC and a phone line and a fax line.
Thanks for the video and your effort.
I’m reading on the product information page for bulk cat8 cable that most Ethernet ports on devices are not properly grounded. Do I need to ground the shielding somehow, or is it just overkill? Trying to search the Internet and not really getting a clear answer.
e.g. product B07JQ2GSFQ on Amazon. Down in the description it states : "Important Note
***Routers, switches and modems with proper RJ45 port grounding recommended. Unshielded devices can generate an "Antenna Effect" and can cause network bottle-necking when used with dual shielded wires.***”
Having grounded equipment or a shielding patch panel should be all that you need. You do not need a separate ground.
I was looking at patch cables today, and it seems that many companies are putting 26 AWG wire in their cat 6A patch cables, but using thicker wire in the cat 6 cable, which baffles me, because i often see like in your chart that you show 23 AWG wire for the 6A cabling. It seems like in patch cables, the more expensive 6a is using thinner wire!
Patch cables are mostly stranded wire and wall cables are solid.
A lot of people don’t actually realise that CAT7 is NOT a TIA standard, and that CAT6a is actually a newer, recognised standard.
Very true but almost every MFG is selling and promoting Cat 7 so either one you get for the best price should be fine.
Thinking of buying Cat 6A, and I'm confused with not finding Ethernet Cat 6a in stores, only Patch Cat 6a, and there isn't anything mentioned in specs of the speed, would patch work the same like ethernet Cat 6a?
Either will work, patch or bulk. The only difference is that patch is usually thinner as it is multi strand wire and usually can't be easier cut and re-terminated. Otherwise the performance is the same. If you are looking for bulk, there is an amazon link in the video description where you can buy a bulk roll. Thanks for the question.
@@MikeFaucher I need 2 cables for PC, and PS4, both connected to router, and with shipping Cat 6a would cost me just 5 Euros cheaper then 2 Cat 8 cables from Wish, what would you suggest, is Cat 8 worth those 5 Euros then? Not so much of a difference in money, but in quality? Both are S/FTP
No not for 10GbE or less. Stick with 6a.
That's why a couple of metres of good CAT8 cable can cost you a lot. I'm sticking with my CAT5e and CAT6 for now. 😂
I never understood why such difficulties in everyday life. Anything higher than CAT5 (6) then the optical cable looks lighter and more reliable.
its true but the optical equipment and termination ,are so much expensive and not worth in less then 100m .
Depends on the environment honestly. Fiber is immune to EMI, while even shielded twisted pair connections are still susceptible to interference. I do agree for the most part though. I would prefer maybe Cat 6a myself.
@@zoli34516 Interference is not important to the digital connection. CAT 7 and CAT 8 are used for gigabyte connections where the range is already limited. At the same time, the price of optical gigabit modules and media converters is cheap. Optical cable is sold terminated for any length - from 0.5m. Optics today trite hopes because of simplicity. Each cable has its own application. In the office, a twisted pair is probably better. Until the switch. Next is the optics. If you are a "heavy client" or a server, then definitely optics. Twisted pair, on the other hand, is easier to repair. There is no need for special tools. It is necessary to proceed from the scope of application.
good video , you shuld also point out that for POE cat6a and above will preform better in terms of power lost
Only for POE+, even then you could see a significant voltage drop over certain distances. Especially in use with balanced wattage applications, a larger conductor will hurt at a certain point. I think Cat6a is actually the sweet spot for this as far as carrying power is concerned.
I first use some cat 8 about 8 years ago, the termination were diabolicle
I am sure it was. Thanks for the feedback
ya I am gonna stick with my cat 6a for now
As you should.
A nice walk through and your conclusion is in line with what I feel atm.
For most soho installs I tend to go for Cat 6 or 6A as well.

yeah you'd be amazed just how annoying it is to be stuck on 1Gbps for local stuff once you get used to 10, 20, 40Gbps.
I have two servers that share large VM disk and and pass on the whole X session over ssh.
It would be a pain to manage them over 1Gbps, instead I bought some "old" HP 10Gbps dual port NICs from ebay and sat them up in aggregated mode to get the 20Gbps full duplex (or like the marketing would say 40Gbps) Before that I was actually facing the issue that the router would be the bottle neck and all the trafic would be caped at 500Mbps because it had to send 500Mbps up and down to each server making it "1Gbps" but not really.
Like Zorro I'm lucky to have 1Gbps internet, but I wish my ISP would give me access to 10Gbps, not just for blazing fast por.... "creative content" but for actually start to migrate some of my network over to local data centers around the city, as of right now it's just not worth spending money on external servers if I'd be limiting myself to 1Gbps.
it's fast for sure, but not really fast enough for really heavy data (as seen from Linux Tech Tips)... but then again it wouldn't be 30 dollars (299NOK) a month either :D

After I save up some money, I would eventually like to setup a mini home server, and network station, instead of needing to rely on my ISP's supplied cable modem.
@@Valentin119
TL;DR
I'd recommend you take a look at SFP instead of RJ45.
There's a lot of "old" discontinued server hardware on ebay that you can get for cheap. when I was looking at 10Gbps upgrade I saw the Asus 10Gbps Ethernet card and it cost 140USD for one single card, without cables included...
...........................................................
Buying something like:
2xHP NC523FP with two 3M DAC (cable) = 85aus each so around 121USD for the whole thing that can do 20Gbps up and down. that's what I got and the only downside that it's only 3 meters cable (max 5M on DAC)... but both servers are located 2µm from each other :P
I'm considering building an outside storage box for the servers (kinda like they did on Linus Tech Tips with their outside water loop)
You can then go with fiber you can still get the NC523 or a similar dual 10Gbps NIC (some even go up to dual 40Gbps for cheap) and for connectivity you'll need the HP Blade System c-Class 10Gb (16USD) adapter and 30M Outdoor Field Fiber Patch Cord (56USD)
The downside is that the adapters are kinda specific so you'll need to check the compatibility, and the cables are on the price of cat7-cat8 for 30M but those outdoor fiber patch cord come with a metal shield so it's easier to not break the fiber glass, you can go all the way up to 100M with fiber... but then it get's really freaking expensive for the adapters and quality cables... I trust eBay to sell medium range products, but if I was to spend more money I would be cautious about the actual quality of those fibers anything bellow 30M is pretty standard.
Anyway good luck on your future project, relying on the ISP do give you a decent modem is the stupidest thing we do before investing in a good home network :)

For the male connector you let the wires way too long. It will not pass a certification test.
I've only been retired five years and there are three new cable types. We weren't getting most requests for Cat.5E. Only a few Cat 6.
This is mostly customer generated as to cable type. Most of them have equipment they won't be replacing soon. If they were moving into a building that they're buying and doing major refurbishment I'd suggest going to the highest type emphasizing the cost of rewiring later at a higher cost. I talked a customer who was moving to wire his Unix system with unshielded twisted pair and adapters and patch panels so he could go to a PC system one day.He agreed but wasn't keen on it because his computer person said Unix would always be around.
Well, his building was struck by lightning and everything was destroyed. His computer guru said he couldn't replace it so he had to go to a Windows based network. Thats when my advice was appreciated. They just removed the UNIX system reversed the connections to the patch panels and Digi Boards and the network was running.

Perfect video. thank you :)
Awesome. Glad you liked it.
Lol, there is no such thing as Cat-7. That's because category cables are governed by the TIA/ANSI standards organization. Back in the mid-2000's the TIA was about to ratify Cat-7, it was the final draft. Then suddenly another standards org from Europe called ISO took the final TIA draft, and published the standard itself with a few minor changes. It was a dramatic coup d'etat, they were actually trying todo a hostile take over a cable spec from its standards body. Well anyways, nobody recognizes Cat-7, because it was not legitimate, because the TIA still was the governing standards body for category cable. So TIA renamed their standard as Cat-6a, and enumerated Cat-8 & Cat-8a so they could not be leapfrogged again. The only network equipment company that accepted the ISO Cat-7 spec was Siemens, a European company. The rest of the world simply ignored Cat-7, and so should you... Because it doesn't exist, it's not a TIA spec.
Thanks and you are correct however though not ratified MFGs are selling it as cat 7 and most have consistent specs. To ignore it would not be fair to people looking into cabling. Thanks for the expertise and sharing it.
@@MikeFaucher I disagree, both Cat-6a and the so-called "Cat-7" have AWG-23 wires, which go into (and beyond) the 750Mhz band. One spec says 500, the other 600.... But both cables are electrically equivalent in reality. So please, just ignore cat-7
@@JonDisnard Understood. Thanks!
@@MikeFaucher btw, not trying to be contentious. Sry about that. Love your videos! 👍 For more context, the TIA wanted to take a more conservative approach, they were more focused on the idea of 100 meter cable length guarantee, so they wanted to balance wire gauge vs insulation/shielding, with a bias towards being as minimal as possible. These topics were debated during the draft process, and some entities didn't like the chosen outcome. The ISO observing this decided to intervene. This is a gross over-simplification, and the drama doesn't really matter. The prevailing point is cat-6a cables are for all intentions & purposes... Equivalent to cat-7, but the later is not a legitimate standard. The only difference that matters is the QA process, where cat-7 must maintain 600 MHz modulation, cat-6a tests at minimum 500 MHz. That said, in reality the various cable testers use 750 MHz, and get to say the cable exceeds the spec. 23 awg easily meets that spec, but attenuation over distance degrades, so shielding... The ISO spec was less concerned about distance, presumably fiber filed that space, so they specified just enough insulation to handle a row of racks in the data center, about ~30 meters, and we get cheaper cables with a nominal bump in modulation.
Thanks for the insight as you obviously have a lot of knowledge so the input is appreciated. No need to apologize as I completely understand and agree with what you are say that it is not a certified product. This is a classic case of MFG building ahead of ratification as they did with WiFI 5 and 6 and never pulled the product before approval. Anyway, thanks for the input and thanks for watching.

Couple of questions:
do you think the connectors on aliexpress are really cat8.
And does it slow that much down that you cant get the rated speeds if you use real cat8 cable and cat6/6a connectors?
Do you know some make cables that are for sure cat7a+ / cat8? Because i think there are a lot of fake/outside specs cables.
And the last question, i cant find any stranded cat7a+ / cat8 cable, does that mean all are solid, so from wall socket to pc that needs to be also solid?
Its not RJ-45 Connector its a 8P8C modular connector RJ-45 is registered Jack 45 used in telephone modem connections where pin 4 and 5 are tip and ring and 7 and 8 are connected to a resistor that indicates the signal loss from the central office to the Modem. It would be good if the bad naming stopped being perpetuated by instructional materials. Like many other things people uneducated it the actual facts picked up the name and used it for a different purpose; then it gets added incorrectly into the common lexicon by marketing people and volai suddenly it starts to be used incorrectly by even less educated people
Looks more like RG coaxial cable but with more core wires.
Whats the difference between A config and B config?
The only real difference between these two are the green and orange pairs for backward compatibility with older phone systems. Most patch cables that are bought today are "B" and this is the standard for the US, however in Europe I believe they mostly use "A". As long as it is uniform in your network, it really does not matter but most new installs are using "B".
Why would you use Cat 8 instead of fiber?
I wouldn't unless you needed RJ45/Copper to connect which is more flexible. Fiber is better for longer runs and is very cost effective as long as you buy pre-made cables.
Cat 8 will be mandatory with the upcoming docsis 4.0 due to frequency
Thanks. Look forward to 4.0.
@@MikeFaucher do you know the coaxial cable specs that are required for docsis 4.0 ? im guessing we also need to change the cable due to frequency increase to 1.8ghz in docsis 4.0
@@LivingTheDream77 No. have not researched it yet.
I would listen to this man explain how to watch paint dry. Great video!
Awesome! Thank you very much for the comment!
@ 2:34 in the video, a lot of the CAT6a i've bought in the past 2 or so years looks nearly if not exactly identical to that CAT7, so long as it's SFTP or FSTP aka fully shielded twisted pair.
You are right as they are almost identical except for a slightly larger conductor (most of the time).
@@MikeFaucher d seem exceeding spec is not issue, at least with some 6a which i think some is even 23 gauge. but, cat 7 REQUIRES these features. 8 seems to be a true upgrade. mostly best for data center. or equipped to deal with PoE++ which can push 75 watts of power minus overhead. EDIT: also 25gbit on 6a through 8 would be interesting to see
Does that mean that the flat ones sold on Amazon, with obviously a lot less shielding, are non-authentic?
Many of the patch cables use multi-stranded wire with is much thinner so the overall is much thinner. The bulk wire in this video uses thicker solid wire.
There is no IEEE CAT 7, Just 6a and 8.
True it is not certified by the IEEE but it still is a product that most cable vendors are supporting. Thanks for the input.
@@MikeFaucher It's not certified by any major certification organization, rather it was REJECTED which means its not a standard and should be stated as such. By including it as a standard in what is an 'educational ' video its giving credence to the idea that it IS a standard.
Also T568A is the better of the two wiring schemes because its required for any US government project and is backwards compatible . T568B can't be used on a government job nor is it as backwards compatible. There is no downside to using T568A but there is to T568B.
I´d use a pipe and go for the 6a so if in the future there is a need to upgrade this is pretty easy and you can do it where you really need it
Good idea if you can get some conduit to the location.
Thanks gamer grandpa 😂
I just needs to throw a bro, bruh and dude here and there lol
yes there is a difference 8 is higher then 7 that's why cat 8 is different then cat 7 you should use it cause it's a higher number and that's why you should be using it lol
Where on earth these came from? I just upgrade from Cat5 to Cat6 and even that by premade cable._
It's three years later, are there even 40 Gb/s RJ45 switches / network cards to make use of CAT 8? I feel like doing singlemode fibre for 10+ Gb/s is way more flexible. I mean, you can push 25 Gb/s or even faster trough fibre for many tens of miles / kilometres. And tbf, I don't believe I'm saying this, 10 Gb/s for in-house (home use) copper cabling is enough, for faster stuff, use fibre instead. So just use CAT 6A instead of the more expensive CAT 8???
I certainly agree with you. Fiber for longer ranges is much better.
