Great video and very much needed. Mr Paddison did great job in converting his vast knowledge into an understandable language for the people out with the industry. I have worked in the industry for 40 years, so I liked his patience and modest delivery, both qualities I personally lack. My company is based in South Korea.
This is fantastic. Massive props to Wildanet who answered all the questions really thoroughly where other people would have claimed "commercially sensitive". But the fact you didn't has created an outstanding video that will have a niche audience, but a fully served one. Thank you so much.
This has been one of the most interesting technical video's I've watched in a long time, especially as I've been considering getting mine connected up. I was especially interested in seeing the installation from the pavement to the house and now know what to expect.
Thank you for an engaging subject, so much of what is on the internet is simply a waste of time but this was facinating to learn and understand how stuff works. I am having FTTH installed next week I now know what the Boxes will do, brilliant and thank you Wildanet for enabling Cornwall and Devon to join the rest of the UK in this cyber space.
Very interesting video, very many thanks to Mr Paddison who transfers his vast knowledge in a way that that makes it understandable to a layman IT guy like me!!
I've always wondered about the technicals involved in the installation...but thanks to your video from start to finish I the whole process was very fascinating and knowledgeable! Absolutely great to watch :)
Great educational video that deepened my understanding of the optical communication industry as a professional. The work on the UK's FTTP project holds valuable insights for other countries as well.
Super video. Many thank and great that Wildernet allowed access to engineer rather than the marketing men. Interesting contrast to the industrial control fibre networks I have seen where fibres are splices to patch boxes and switches not passive splitters are used.
Very interesting chat and tour! Fibre was run under the pavements where I live a few months ago, and I'm thinking of switching to a fibre service shortly, so this was very informative indeed regarding how it all works. Hope to see a video about your fibre installation in due course!
Thanks very much sir for creating and presenting this video it was really informative. It was great to see your guest explaining how they get the fibre network to the customers premises and how it all works. Thank you for sharing well worth my time watching.
Wildanet’s subcontractors are doing the groundwork in our road at the moment. I have just found this video and found it fascinating and really useful. Great to have engineers answering the questions and going into exhaustive detail about the processes involved and the reasons behind them. I now know what to expect and can’t wait to order my connection. Unfortunately I still have 8 months to go on my TalkTalk contract. Maybe there will be some early bird discounts that make it worthwhile paying talktalk cancellation charges!?
this was very interesting to watch thanks for allowing it to take place seeing the behind the scenes for wildnet internet connection, it was so so interesting to learn about the back end systems
Really interesting build, very similar to Virgin upto the Toby. I take it that pre connectorised fibre is also used from the external box on the wall to the ONT, when you get yours I’d be keen to see this outside/inside cable being installed.
Fascinating video. Well done. When my house was built in the 1980's trunking(?) was laid to each house for the copper, when they came to change to fibre they pushed a "wire" back through from the house and then pulled a "fibre" to the house. I watched them and no blowing was involved for us. I assume there are different methods according to what is needed.
A key thing they are aiming for here is no joins between the optical splitter and the house. That dictates a lot of what happens in terms of the best way to get a fibre all the way from the optical splitter which may cover several roads, all the way to each house.
I think Openreach do it differently to companies like Wildanet. I have CityFibre and they have done it in a similar way to in this video, except the straws are fed through the existing ducts, and the splitters are in green cabinets they have installed rather than under manholes. Openreach have installed connector blocks called connectorised block terminals in the manholes, and I believe they pull a fibre through the duct and connect to those.
With regards to latency across the pond, there's few options to reduce it - physics gets in the way. Even at the speed of light (which is not achieved anywhere in a fibre network because c is a constant in vacuum, and optical fibres aren't vacuum) with a direct line of sight (also not happening), the distance to the US is simply so great that a very measurably higher latency is a fact of life. What can be improved is the consistency of the routes, however. E: I should note, though, before anyone does the simple numbers on the path and goes "but that's only 19ms!" or something around that figure - velocity factor of about 0.65, plus the next harsh reality of attenuation. Every single repeater stage adds latency. Add onto that routing inevitably requiring processing time. The latest and greatest cable, Amitié, is managing about 34ms between Bordeaux, France and New York. That's near ideal with no routing.
There's a physical limit to how low you could make the latency to US because of the large distance. Also light travels a bit slower in fibre than in a vacuum dependent on the refractive index of the fibre. Then the light has to get there and then the light for the answer has to come all the way back from say a US based server. A large chunk of servers are on the west coast (where high tech companies are mostly based) which makes it even worse. For the latency to west coast the highest part is from east coast to west coast and the smaller part is trans-atlantic latency. Also fibre doesn't go straight across the USA but via various cities. Also going across land there's probably more store and forward switches in the path which also adds latency (can't send on a packet till all of it is first received and stored). Trans-atlantic there's no switches in the middle of the ocean, only repeaters (amplifiers) in the cable. I get asked all the time "I want latency < 40ms to USA" which is physically impossible because of physics and distance and then I do the approx propagation delay calculations and send it to them to show it.
Very interesting video. Cityfibre laid fibre in my street a year ago, but by then I had signed up to Three with their 5G service which works very well, 610Mbps dn/65Mbps up and is cheaper than a similar fibre service. I wonder how 5G has affected Wildernets roll out plans?
Very interesting video, I've watched them instsll it around here and snd this has explained how it all works very well. I'm not sure he's right about transmission from the ONT being randomised though, from what I understand it's all orchestrated by what's at their end, with timeslots assigned to each ont taking into account the differing delays that occur because of the differing fibre lengths. I wonder how long ago these little providers will last for before they start merging together.
Genuinely interesting video. I guess the only question I had was what level of redundancy did they have at each stage. But, very eye opening and exactly what I was looking for. Cheers
Great video. As Paddison said, ping an idle ip address when the network is not congested and then when it is ping same ip address again and compare the time. If it’s high then your router/ap is cooking. Obvs don’t use your dads pc as the ping endpoint when he’s uploading cos that will show false positive
It's wild that other countries already use 10gig PON for 1-2 years now and in Austria normal 2.5gig PON is newly deployed now with no plans to upgrade to XGS in the next 5-10 years. We have a town as a customer that does GPON but offers their customers only 80/15Mbit/s as a max, and they have no plans to offer higher speeds because "we see our customers only using 10-20Mbit on average". 1:01:00 that one I dont understand. Before he talked about their splice attenuation limit being 0.1dB max (we have a limit of 0.2 bec 0.1 is very hard to reach especially with different fiber manufacturers. If we have to mix G652 to G657A1/A2 we have a limit of 0.4) but then the only thing that matters with the customers drop is the light level being between -14 and 24dBm. Why do they even care about a splice being under a certain limit if the whole drop isn't OTDR tested afterwards.
I wonder why microbore copper tubing couldn't be used to carry the Fibre Optic cables and offer protection from anything that might want to chew on the cable.
Very interesting. One point though, unless something has changed, PSTN switch off is 2025 not 2027 as stated and new orders stopped in September just gone.
youtube removed my like on the video from a few months ago when I first saw your 2 videos on the setup. was talking to my uncle about the mini documentary yous made I know I liked and subscribed with both of my accounts at the time, and when i've came back to watch again youtube has removed my subscribition and my likes on both videos, so i'll be readding them.
Interesting to know how you worded the muted bit at 1:19:20 I have no interest in Wildanet as I prefer my current ISP - no block,s no shaping, no port blocks etc.
Being with Wildanet myself, I can tell you there are no blocks I've encountered (ignoring government forced DNS things you can simply ignore at will), no shaping I've noticed, and only port 25 inbound blocked (which I wasn't overly happy about but a pretty minor issue).
@@Monkeh616 That's for that. I really like my current ISP and lets hope Wildanet opens up to wholesale to other ISP's. Port 25 blocked is annoying I fiddle web email severs etc etc. I'm not used to blocks. Apparently they 'prioritise' Netflix etc which is shaping.Also a fibre split ratio ratio of 64:1 is high. That's 10G shared between 64 households - remember with a PON only one ONT can TX or RX at once ...
@@myozone At the max rate of 900Mbps, that's a contention ratio of approximately 6:1, assuming all ports are in use and all subscribers chose the max rate - neither is likely. This is quite acceptable. Upstream is actually only 3:1. GPON (at 2.4Gbps) and NG-PON2 (at 40Gbps - think of it as four XG-PON networks spread across wavelengths) can then be run simultaneously if there's demand, with only changes at the OLT and ONU (ONT). RX is not TDMA, fwiw - TX is, though. No network can sustain maximum utilization from all customers simultaneously. The old phone network couldn't, the electricity network cannot, nor can water or gas. Thankfully, they really don't have to in practice.
@@Monkeh616 I agree and understand what you are saying. That's 6 of the 64 downloading could max out that string. As a potential user I would down and upload terabytes of data - 4k video etc, you would only need a few p2p users to max it out ...
@@myozone Thankfully, users like ourselves are pretty much one in ten thousand or less. And rarely affected if we don't reach maximum speed 24/7. And no, that's 11 - 10,000Mbps, max customer rate 900. 64 x 900 is 57,600, so contention is 5.76:1, but 10,000 / 900 is 11.11. I seem to recall the actual line rate is 9.5Gbps but we'll gloss over that. This little mathematical oddity is one of the reasons contention ratios are difficult to compare.
Youll be suprised how poor of a connection you need for gaming. I tried my 4g the other day at best 5mbps where i am and ping in the 60s and it was perfectly playable while streaming to youtube. I dont know how but it ran pretty well. Friend of mine uses his 4g all the time at work to game and works absolutely fine never notice him lagging or anything like that.
@27:00 Yes, the ONT is a "modem". It bridges ethernet from the customer into the PON. In the fiber, it's GEM, not ethernet. (EPON is ethernet, but let's stay out of the mud.) There are no collisions because the OLT ("headend") coordinates who gets to speak when. (ages old TDM technology) As much digging through Wikipedia as you've done, you should've seen all of this by now. As the CTO (and one of the founders), he should definitely know all this. (this just reinforces the mantra "never ask an executive to explain anything.") @36:20 Angled connectors are used to mitigate REFLECTIONS. It's SINGLE-MODE, so there is no dispersion. Jez. It's not DSL; distance does not slow it down. The longer the span the greater the attenuation. At some point the light levels will be too low to function reliably. This has NOTHING to do with speed. [it's a factor of fiber quality, and receiver sensitivity] (if anything, in fact, it's the opposite. Receiver sensitivity has improved over the generations. So a BPON ONT at 10km might not work, but a newer GPON should, as should XGS) VDSL uses PTM, which is an ethernet-like encapsulation. ADSL uses ATM, which made some sense in the late 90's when it was designed - many backend carrier transport networks would've been ATM (or frame-relay) Today, pretty much _everything_ is ethernet, so modern things are designed to transport ethernet. (eg. AT&T Uverse's ADSL is "IPDSL"... they had custom firmware designed to do PTM over ADSL. I've never seen anyone else ever do that.)
I was asking about collisions because the video was intended to explain what's going on, not for me to look it all up on Wikipedia in advance. I came to it from the background of having worked on the transceivers around 20 years ago at Nortel. There is some explanation of the terms here: www.lightoptics.co.uk/blogs/news/pon-network-understanding-olt-onu-ont-and-odn
Can’t understand why they are not symmetric. The explanation of ‘that what the market asks for’ doesn’t really wash. I have Toob fibre and they provide 900MB/s symmetric (and in Barcelona I have 10GB/s symmetric). Surely only a small percentage of users require fast upload speeds, so it’s not as if it would swamp their network.
I know, but at least Wildanet upload is merely half download and they may change that in the future. Until recently Virgin Media in the UK had upload at 10% of download, and recently have increased to a massive 20%.
That's fine, you can carry on with copper to the cabinet. What will change though by next year, is that the dial up phone service will end and your landline, if you use one, will need to connect to broadband either using VOIP phones or via an adaptor.
@@video99couk I use broadband using normal copper network speed of 30 meg. I don't need 600 or 900 megs speed and also rewiring of the home phone sockets and using ONS box. They left the fibre cable outside and will drill holes to put a box inside . Can I refuse to have it installed?
Copper connections will eventually end. Firstly in new builds, then for all repairs, then for all. Its like the switch off for the pstn, the existing equipment is at the end of its supportable life, going to viop is going to be a huge cost saving to open reach, it is already no longer possible, in most areas to request a pstn connection. A massive bonus will be the value of the copper to be recovered.
You can get 150mbps FTTP at a lower cost, Fibrehop offer it for £26 a month. At some point FTTP will be the only option and if you refuse to have it installed then you won't have an internet connection.
It surprises me that you use little plastic plugs to joing the fibre together, does not seem a very reliable way of doig it to me. In New Zealand we have had Fibre to the Home for many years now. Any time we need to join the fibre we use Fusion splicing to weld the fibers together. The prepared fiber ends are brought together and subjected to localized heating using a laser, the heat causes the glass to melt and fuse, creating a seamless solid connection. Its all done using a small handheld device. Why do you not use this method in the UK?
Because it requires performing that process down a pit in the rain. Preterminated connectors are faster, less error prone, and readily exchanged. Fibre connectors are very reliable - this video came through dozens of them to get to you. Nobody is fusion splicing cables into servers, switches, routers, OLTs, and so forth.
Then either the router has to be firmly mounted to the wall, not ideal, or the fibre is flopping about and can get stressed, even worse. That's why this solution is rarely seen, it's not good either way.
Sadly some areas will never get fibre, even villages with hundreds of homes. Yet a farm in the middle of nowhere gets FTTP!!! Numerous poles and civils for 1 farm.
@@8skellerns Many farms also get overkill 4G/5G reception as well!. EE likes to boast about their coverage around farm land thru advertisements, but the same cannot be said about villages 'n' cities, it's anything but useful for the modern day as speeds are similar to ADSL version1! But visit farm land and speed is at 80Mbps over 4G!.
@@8skellernsI know, they are shutting down the data service to 3G and 5G is eating up all the bandwidth which is making 4G look slow or look alike poor reception to sell more 5G capable smartphones, albeit even 5G is having problems since major celluar companies are using huawei gear on their towers, and it's just poor quality crap so the providers can cut costs and forward savings onto customers.
@@nigelsmith421 I do, although I thought he said training and servers at one point.. beyond that on principle, training or irl cabinet tidy habits should be promoted imo, that’s not a good example even if it does represent more real world small to medium installs it should not be the norm these days.

(ages old TDM technology) As much digging through Wikipedia as you've done, you should've seen all of this by now. As the CTO (and one of the founders), he should definitely know all this. (this just reinforces the mantra "never ask an executive to explain anything.")
@36:20 Angled connectors are used to mitigate REFLECTIONS. It's SINGLE-MODE, so there is no dispersion. Jez. It's not DSL; distance does not slow it down. The longer the span the greater the attenuation. At some point the light levels will be too low to function reliably. This has NOTHING to do with speed. [it's a factor of fiber quality, and receiver sensitivity] (if anything, in fact, it's the opposite. Receiver sensitivity has improved over the generations. So a BPON ONT at 10km might not work, but a newer GPON should, as should XGS)
VDSL uses PTM, which is an ethernet-like encapsulation. ADSL uses ATM, which made some sense in the late 90's when it was designed - many backend carrier transport networks would've been ATM (or frame-relay) Today, pretty much _everything_ is ethernet, so modern things are designed to transport ethernet. (eg. AT&T Uverse's ADSL is "IPDSL"... they had custom firmware designed to do PTM over ADSL. I've never seen anyone else ever do that.)
I was asking about collisions because the video was intended to explain what's going on, not for me to look it all up on Wikipedia in advance. I came to it from the background of having worked on the transceivers around 20 years ago at Nortel. There is some explanation of the terms here: www.lightoptics.co.uk/blogs/news/pon-network-understanding-olt-onu-ont-and-odn
No one asks for slower upload? They could differentiate with symmetry...
Can’t understand why they are not symmetric. The explanation of ‘that what the market asks for’ doesn’t really wash. I have Toob fibre and they provide 900MB/s symmetric (and in Barcelona I have 10GB/s symmetric). Surely only a small percentage of users require fast upload speeds, so it’s not as if it would swamp their network.
I know, but at least Wildanet upload is merely half download and they may change that in the future. Until recently Virgin Media in the UK had upload at 10% of download, and recently have increased to a massive 20%.
I have FTTP via CityFibre and that's symmetric too.
What if i dont want to switch to fibre. i dont need 600 or 900 meg
That's fine, you can carry on with copper to the cabinet. What will change though by next year, is that the dial up phone service will end and your landline, if you use one, will need to connect to broadband either using VOIP phones or via an adaptor.
@@video99couk I use broadband using normal copper network speed of 30 meg.
I don't need 600 or 900 megs speed and also rewiring of the home phone sockets and using ONS box. They left the fibre cable outside and will drill holes to put a box inside .
Can I refuse to have it installed?
Copper connections will eventually end. Firstly in new builds, then for all repairs, then for all. Its like the switch off for the pstn, the existing equipment is at the end of its supportable life, going to viop is going to be a huge cost saving to open reach, it is already no longer possible, in most areas to request a pstn connection. A massive bonus will be the value of the copper to be recovered.
@ll1665 The money from copper, will go straight to the bosses as a "Christmas Bonus" rather then anything else.
You can get 150mbps FTTP at a lower cost, Fibrehop offer it for £26 a month. At some point FTTP will be the only option and if you refuse to have it installed then you won't have an internet connection.
It surprises me that you use little plastic plugs to joing the fibre together, does not seem a very reliable way of doig it to me. In New Zealand we have had Fibre to the Home for many years now. Any time we need to join the fibre we use Fusion splicing to weld the fibers together. The prepared fiber ends are brought together and subjected to localized heating using a laser, the heat causes the glass to melt and fuse, creating a seamless solid connection. Its all done using a small handheld device. Why do you not use this method in the UK?
Because it requires performing that process down a pit in the rain. Preterminated connectors are faster, less error prone, and readily exchanged.
Fibre connectors are very reliable - this video came through dozens of them to get to you. Nobody is fusion splicing cables into servers, switches, routers, OLTs, and so forth.
We do use this method in the UK to different providers have there own processes
It would be handy if they could just hand off the fibre directly as some of us have real routers that have fibre ports :P
Then either the router has to be firmly mounted to the wall, not ideal, or the fibre is flopping about and can get stressed, even worse. That's why this solution is rarely seen, it's not good either way.
If VIRGIN is available in your area then maybe they might be able to provide a much better service.
They aren't, and their upload speeds are rubbish anyway.
Sadly some areas will never get fibre, even villages with hundreds of homes. Yet a farm in the middle of nowhere gets FTTP!!! Numerous poles and civils for 1 farm.
Gotta keep farmers happy as they feed every 1.
@@smiths7317 😂
@@8skellerns Many farms also get overkill 4G/5G reception as well!. EE likes to boast about their coverage around farm land thru advertisements, but the same cannot be said about villages 'n' cities, it's anything but useful for the modern day as speeds are similar to ADSL version1! But visit farm land and speed is at 80Mbps over 4G!.

@@8skellernsI know, they are shutting down the data service to 3G and 5G is eating up all the bandwidth which is making 4G look slow or look alike poor reception to sell more 5G capable smartphones, albeit even 5G is having problems since major celluar companies are using huawei gear on their towers, and it's just poor quality crap so the providers can cut costs and forward savings onto customers.
I have this Wi-Fi, probably one of the worst I’ve ever had Everything seems good on their end, so they don’t care and won’t come fix it
There's no such thing as 'The Cloud', just other people's computers. Who do you trust? Do you feel lucky?😮
1:10:43 I was grooving along fine until here and then they show that cable nest... NO THANK YOU, these guys can go blow down someone else's straw xD
You know it is just their training setup - which is likely to be connected/disconnected on a regular basis don’t you?
@@nigelsmith421 I do, although I thought he said training and servers at one point.. beyond that on principle, training or irl cabinet tidy habits should be promoted imo, that’s not a good example even if it does represent more real world small to medium installs it should not be the norm these days.
