@Xoujiro that's just a beach-side demo to show you what it does underwater
-
the technology we have is ridiculous, and it's only getting mower advanced. very, very fast.
here in the middle of the US, i can send data to a computer in the UK in well under 150 milliseconds. not only that, but i can transfer several megabytes per second to it without giving it a second thought.
we've gone from the 8088 CPU in 1979, to being able to buy close to 4 GHz six-core CPUs. so, what about in another 30 years? :o
-
do they put it under the deep seabed or just at the beachside?
-
Nowadays they have converters that just use light to amplify the signal again, which is harder to intrude by hackers etc.
-
@LURTSCH MM, are you serious? Submarine cables are by nature layed for LONG distance while MM fiber is for VERY VERY SHORT distances.
-
its because dispersive effects are only evident in coper conductors that are significantly large in length.
-
I wonder how many strands are in that cable. Is there even an indicator in the video that shows whether it's MM or SM?
-
How far man has come.
-
It can reach 1gbps. otherwise it would be a complete waste, why would they bother using fibre if it doesnt reach insane speeds? they might as well use cable.

The video is rather old. Modern cable systems use optical amplifiers, there are no optical - electrial - optical conversion. Repeater type systems are no longer in service. Modern sytsems typically use 4 or 8 fibre pairs, each fiber pair supports multiple wavelengths of light (DWDM) - for instance a 4 FP could support 96 x 10Gb wavelengths x 4 FP's giving a total of 3.84TB. Also more recently manufactures are introducing 40Gbp wavelengths and in the near future 100gb wavelengths will be appear.

What would power the repeaters? are thay battery powered?
