The world economy and every Internet user hangs on the overseas cables. What actually happens when you enter an Internet address? The film shows how the message reaches the recipient. What happens, if one of the cables in the ocean breaks and how to fix it? How the data cables are produced and laid? What the scientists must think of to get even more data at the same time through these and what role the ominous sea mouse plays in it? How overseas cable technology has changed since the turn of the century and what visions the scientists have for the future?

Great documentary. It's interesting how much technology and work has to go in to global communications that we can take pretty much for granted each day. Subbed to this channel.
Aboard our destroyer we happen to see two of these vessels laying cable on the ocean floor extending communications. Great Work!
Indeed, in 2020 we take it for granted but not so long ago that was top tech, now is VR, who knows what it will be in 2030. I still remember my 28k modem...

Why would they put cables underground if there’s satellites in space and satellite towers every 5 miles
@@RiteSideup-nh6kn It's cheaper and arguably less vulnerable. Hard to shoot down or be hit by space objects. Also harder for hostile actors to intercept or disrupt transmission. Also easier to repair. Also much, much higher reliable bandwidth.
This might be more interesting, for some people, if some of the diagnostic procedures were explained. For instance, @7:02 , that instrument performs Optical Time Domain Reflectometry (OTDR). It sends pulses of light down the fiber optic cable, to the break. Then, the light is reflected back. It uses that time difference, to calculate where the break is.
This is also done on electrical cables. (Except that it’s called TDR, instead of OTDR.) Electrical pulses are sent down the cable and get reflected back. Again, using the time difference, the ‘distance to fault’ (DTF) is calculated. If you have a mile of buried cable, with a fault in it, it makes sense to only dig up the area, we’re the fault is.
Another use for TDR, is when trying to determine how much cable is left, on a cable reel. If you need to run 150’ of network cable, but don’t know how much is left on the cable reel, most people will just grab a fresh reel. (Who wants to run short and have to run it twice, right?) This becomes wasteful and, soon enough, you’ll have stacks of partial reels, of unknown length, laying around. Attach a TDR instrument to it, and you’ll know exactly how much is left.
I love insightful YT comments, thank you
None that reel end testing 100's of times.
Looking for macrobends is
Much better challenge. Higher wavelengths, faster speeds
Now I really want a TDR. Where can I get one ?
@@Desuetus If you’re curious look up Viavi or Exfo
@@Desuetus Check your switch! If you got a managed switch it may have this function built in. Mine does.
Never realized there was so much underwater cable for the internet. Documentary was very informative and opens one's eyes as to what goes in and out of our computers around the world. Very well done.
Proud to be an Fiber Optics Engineer.Its been 10 years of achievement and satisfaction.
I love the way this documentary is covering all sides of the subject from the history and the various people working on a typical given situation. Good work, will be looking into other of your documentaries !
Thanks for the documentary, really appreciate your work and of those who work around the clock so that the world can stay connected.
That this first graphic does not show the true line of the first cable to cross the Atlantic. It did not go from the UK to the United States. The first cable was laid by the Great Eastern and went from Valentia Island, Ireland to Heart's Content, Newfoundland. The cable was landed in Heart's Content in 1858.
Awesome documentary. In just over forty minutes, I learned how extensive the undersea fiber optic cable system is, the history of undersea cables, how they laid and repaired, and also how fiber optic cables are manufactured. All that in a 2010 French documentary that remains fresh and relevant in 2020. Bravo.
Thank you for your comment! But it is actually a German production that has been aired on the German-French TV channel ARTE.
I've replied to myself. Thank you silly french man
I didn't know we allowed Germany to rejoin the human race
Arte
@@stephentaylor4144 now That's funny . . . . silly Frenchman!
Finally. I have been searching for a documentary about this. Thank you. Now I fully understand. if only they also showed in more detail the cable landing stations and how the cables connect to ISPs
Fascinated to see an actual repair operation. Amazing !! Such a detailed, well directed documentary. I know so much more about fibre optic cables that connect us
I think about these cables a lot. I like the numerics driving convergence. It is fun to think about while sleeping/waking. I picture this standard keyboard in my head, except each key is a spherical screen which can project a display. Even by just sequencing colors together, the standard Clavichord is enhanced and even is given analog features, it is a cool idea I always think about in my head.
I want some of whatever your smoking bruh.
Dude you gonna share those tabs?
@@scaredfolks5923 no cap
Bro I was finna say the SAME. EXACT. THING. That shit is crazy, son!
Fascinating. I find it amazing how much bandwidth is in those 4 little strands. Truly amazing.
ya, it is all about the carrier systems attached to them - the big systems called DWM shoot 32 colors of light down one strand and demux the signal at the far end for multiple streams of data inside one strand - hence Dense Wave Mutliplexing . and that was back in the 90s ! who the hell knows what is out there now !! ;)
Especially considering we're currently getting 1 fiber per house and 4 per flat inside the house in Germany as part of the EU-wide telecom network upgrade. So most houses get either 6 or 12 fibers, with the capability to easily upgrade to 24 or even 48 fiber cables in the future.
im a wireman i love the thought of being the first guy to attempt to lay a transatlantic cable. pretty awesome.
That would have really being in the unknown. You lay your cable, put a Morse key at one end and a sounder at the other and nothing particularly happens. You find you can send messages but it is painfully slow because of the capacitance of the cable. You thought it would be OK because on a Sunday you were able to connect enough overhead telegraph wires London to Birmingham to London to Birmingham etc to match the distance across the Atlantic and it worked fine. Unfortunately these wires had a far smaller capacitance to earth than the core conductor of a submarine cable.
Then there were submarine telephone cables that used vacuum tubes for amplification because transistors were not sufficiently proven at the time. The amplifiers were all powered in series at a constant DC current and supplied approximately -1500V DC at one end and + 1500V DC at the other.
What a lovely film, with tons of great footage and explanations!
This was absolutely fascinating. I loved the detail in which the producers of this educational documentary went to,and we actually need more similar videos like this! thank you for uploading it for the world 👍
Get real. Thought this was about cable!
Simply amazing! Thank you for making this!
Thanks appreciate your time and effort you put in to these videos
40:44 the splicers. Most impressive!
I guess that is better than " the cable fixers ". Chortle, snicker, guffaw.
It's a lot of fun sometimes.
This is a fantastic documentary. Most people believe world internet works on satellite communications. People should watch this documentary so they would understand how much work and resources go into making internet possible across continents. This also helps explain why internet is not free. Thanks for uploading.
No fake drama. Old school documentary, good stuff.
Not even 10 yrs old, this is yesterday for me.
Glad Germany's back on track globally, with all that tech genius ;]
People are always complaining about RUclips’s suggestion algorithm, but for me more times than not it turns out to be something rather interesting. I still get dud’s sometimes but I don’t click on them I just keep scrolling down.
Yeah i imagine most those people watch dumb shit to begin with. It usually does a pretty good job matching you with things you have previously watched.
What an amazing quality! These 43 minutes were incredibly interesting.
Really interesting and great documentary ever for Telecom Field
Excellent doc. Makes me wonder how much competitor cable sabotage goes on.
Very educational. Easy to understand the basics of this problem.
Awesome explanation of how submarine cable works...expecting more videos like this
This was super in interesting!
Much love! More info for everyone!
I remember working at lucent technologies and being presented with videos of the trans Atlantic fiber lines being dropped from the bow of a large boat. Very cool.
I used to subcontract for lucent tech building fiber optic cleaving devices to splice repairs. I also co-developed an inspection devise to rapidly inspect individual strands of fiber optic. Amazing technology. What amazes me is that most people think the internet is thru space and satellites.
i never thought it was this hard to keep those cables working, & all tht manufacturing work & research
This is an excellent documentary. I enjoyed it very much!
at the end when he said "maybe we got some measurements incorrect" i felt like someone is going to be a dinner for the sharks 😂😂
Outstanding world class documentary.
Holy the light at 15:46 following the water is crazy.
GREAT video! Very informative.
Fantastic documentary!
Amazing documentary!!!
Great documentary. Very informative about the undersea cables.
Excellent quality documentary, thank for sharing
nice, this is how i can play counterstrike and runescape with europe from canada
runescape is dope bro. havent played in years but have an account with 100m on it aha. still watch Yt OSRS vids to this day
@@bobbytroy3443 100m is nothing tbh..
The whole network is made up of fiber. ISP's only use phone lines and coax for a short distance to feed homes, the rest is fiber.
Alot is going satellite also. So you don't know exactly what your on at any time.
@@shawnshurtz9147 Satellite is still very slow compared to cable/fiber. I know I am always on fiber all the time. My ISP never relays to satellite, ever.
I live in SF, CA.
This is really interesting.
I'd be curious about some of the financials as far as who owns the cable(s) - what the rental rate is / etc etc
@Anon Person all you gotta do is install your own trans ocean submarine cable and all the nessesary equipment and you can have all the free phone calls you want douchebag !
Me too.
@@scottbarlow1397 Bill Gates will sabotage any and all democratic people's cables.
@@jimgritty7064 thanks for the heads up . . . .I'll be on the lookout for old Billy boy!
Big Telecom owns the cables governments pay for it through taxes everyone uses it in essence we all pay for it and we all own it
these documentaries are so nice , daily dose of reality
Very interesting thanks for posting!
Excellent.....Doc. Awesome stuff... Thanks very much...!
that is perfect what im wanted to know more specific and i tried to find. thanks its so easy and good point mentioned tecnically to knows how under sea fiber cable work for sustain de word wide web.
Great documentry ......A big thanks to the team becase you people our life becomes way too easy.......
An excellent documentary but the intrusive music has likely chased many a viewer away!!
Recommend: Pouring light into a bowl?A great documentary,thanks 4posting :)
It’s like the US Coast Guard’s unofficial motto: “You have to go out but you don’t have to come back”
Lol 😆
This is almost science fiction in comparison with laying the 1950's transatlantic cable, especially the Sea Mouse (19:39) with it's fibre optic fur.
Even more astounding was the 7 years it took to fix the 1st cables break compared with this crews 14 day fix.
Wow! Now that's Maintenance!
This video clearly states...NEVER EVER GIVE UP.💪
I worked on the CS Long Lines for a while.
awesome documentary!
This is so fascinating!
Excellent documentary.
Very nice documentary!
Very interesting thanks for putting that out there
Nice job. Just a handful of people control the world's communications. Scary and brilliant at the same time. Can you run one of those directly to my house? That would be great, thanks.
40:30. Holy shit this is amazing.
In the Netherlands they are looking for a bunch of guy's for this kind of werk.
The network is online and there have bin mistakes and flows.
Very good and interesting information. Thanks for sharing.
Currently undergoing it certification. I learned about this In a lecture and I'm fucking blown away. I had NO IDEA all of this was happening when you go to RUclips
It’s fun splicing, just tedious that’s all, I clean/wipe the fiber often before fusing the 2 ends together 👍
As long as u have it clean and a good cleave the machine does the rest. 😆 lol
So...much.... Cleaning....
Thanks for wiping.
This is great vedio...how we enjoy internet..amazing
I wonder if the repeaters have photonic lounges and restrooms to help refresh them on their journey. Perhaps some small viewing windows to take in the under water scenery while they enjoy the short stay abort the torpedo shaped refreshing stations. One could only hope so
It'd really just all be pretty dumb otherwise ;]
Those poor photons, running back and forth along the ocean, never getting to stop and appreciate the sea mice
Documentary segues into talking about fiber optic cables with a V.92 analog modem training sound.
Thanks for the enlightenment? Very interesting and informative.
That's what I do in NYC Subway system for cell wifi communication. Love this work. 30 years
Thamks a lot.
Thank you a ton for bringing such video🖖🌈🎉
Fantastic! I've often wondered about these underwater cables and how are they possible.
Now I know a tiny bit of it....and know it isn't magic. Damn near though!! Thank you all concerned in this .
Im impressed with that little machine that Splices the Fibers. Sure makes things a lot easier.
Eating on this boat is a dining experience. Out on the town - in a boat.
Amazing and Educational
nice documentary
As a splicer... I'll never complain about opening armoured cable again...
How do you midentry these things?!?!
14 Days , error 33 and error 34 Closed ! Great JOB ! Great Video and production ! They are called " splicers " , you showed a very nice fusion splice system if I am not mistaken ! I learned it several decades ago with the USAF telecom career field. Nice 20 year run. Again - Great Video !!
I lay these networks once they reach land to fiber hubs hours away from the beach. Very interesting to see the longest portions of the project on the ocean.
Not even 0.00001% of the population is aware of the technologies that make today's magical communications possible.
Great upload hello from Australia
great job!
Using light as the transfer medium isn't just genius, its damn near a miracle.
Our communication systems has to be one of greatest wonders of the world.
Epic Education! Ty
Oh, this is about the legendary SeaMeWe3, the longest cable system in the world. 39000 km long, it goes from Germany all the way to Japan and Australia, connecting a whole bunch of countries in between.
The displays with depth (autostereoscopic displays) have the advantage that you don't have to wear glasses but you still have to keep your head exactly horizontal to the screen for the effect to work and it's a bit wavey, the images don't appear very solid and the resolution isn't all that great. I have a better idea. 3D shutter glasses, but with head tracking. The disadvantage would be that you have to wear glasses but the big advantage is that you would get the parallax effect same as looking out of a window and be able to move your head to look around virtual objects without having to stay horizontal.
40:40 "dust free space" might be giving that tent a bit too much credit.
I particularly liked the mud on the walls.
Compared to environments I splice in, that is a surgical room in a hospital.
Amazing. Light beams have been used as tools for decades. Travelling in clear tubes for years. Who thought it was possible to put data into light. I mean that literally. What person or team of people thought that possible.
Vance McCarthy I'd suggest you start here.
en.wikipedia.org/wiki/Fiber-optic_communication
There have been many people and companies involved in the development of the technology going back almost 140 years or so. This wiki article is a decent jumping off point to explore the different applications and many different companies, scientists, inventors and ideas that have been combined to bring this technology to light ( pardon the pun)
I found it fascinating to map out the different advances, set backs and people involved...Hope you do to.
Nice film. I work in application support for the software that manages these networks. I've worked with Deutsch Telecom many many times. Fascinating to see what the guys on the boat actually do. I believe the guys who have the skills to splice these cables are very well paid. I'm network engineer by trade, and a boat guy for fun. This could be my next career move!!
Wow to think that this is old technology is mind boggling.
In the middle of laying cable project when saw this video and been in Teliri as well when she doing cable laying project in Papua Indonesia for Palapa Ring Project.
11:57 fuckinghell. the 3D effects on that spinning watch is just incredible on a normal phone it looks like it's proper 3D.
Wow that technology is mind-blowing!
I know right , theirs a current cable break right now ...
Running data cable under deep sea and getting data thru satellites is fascinating
Great report ! 👍
Holy shit 7 years to fix the first ever cable malfunction. You thought your Amazon delivery was slow after being delayed a day.
Thanks for sharing this informations. 👍
Very interesting.
pretty interesting
One simple cut. And our communications and internet goes down.
Part of me wants it to happen.
Yeah, id like to sit back and watch all the people around me and the world go apeshit and laugh in amusement.
Hopefully not until i have finished watching this though :p
Luckily we have over 250 undersea fiber optic cables across the globe, if one breaks we have others to take it's place until it's fix.
Don s. Which part of you? Are you by chance a colostomy surgeon in need of a vacation?
"ROV.....remote controlled robot".....LOL!
Remote Oceanic Vehicle.
Remotely operated vehical
I'll give a shout-out to whoever knows who has both the ability, capability, and already has operations plans in place to shut the internet down in the event of another major world war, assuming nuclear weapons are not used
