Why would they put cables underground if there’s satellites in space and satellite towers every 5 miles

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.

Thanks for the documentary, really appreciate your work and of those who work around the clock so that the world can stay connected.

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 !

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

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.

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.

Fascinating. I find it amazing how much bandwidth is in those 4 little strands. Truly amazing.

@Wag2112

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.

What an amazing quality! These 43 minutes were incredibly interesting.

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.

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.

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.

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.

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.

Lots of valuable information :) and is strange how cabling is changing to allow more data but more chance of isolation when it comes to power requirement and re-usability etc. Whats really interesting s most of the worlds data runs through about 5 international routers (maybe more now) that if removed or taken out a lot of stuff will cease to work, Imagine being in an apartment complex and only being able to communicate with your floor as there is no elevator or stairs to any other level you know it exists but can't do anything haha Trawling should be banned, way more viable options or cool want to do it buy lake breed fish/crabs etc and then do it, we do not replace enough of what is destroyed or recycle enough
