The Subsea Interweb

By Rob Almeida On January 29, 2014



Below the surface of the ocean, wrapping invisibly around the planet covered mostly with fine mud particles and the carcasses of dead organisms is the internet, in its physical form.

Technology continues to develop in the world of digital communications and as it does, new, faster cables are installed throughout the world. Tyco Communications notes this year they are now installing fiber optic cables which have shown 13 terabytes per second capacity over a distance of 6,500 km. Since 1955, Tyco’s SubCom division has installed 490,000 kilometers of subsea cable, which is enough to circle the earth 12 times on the equator. Other recent cable lay jobs include connecting Chevron’s Jack & St. Malo production rig in the Gulf of Mexico to a 180km-long subsea fiber optic network.

Why dead organisms?

I guess if terrist can take a crappy flight school lesson and learn how to fly 767s and 757s, then I guess they can learn how to take over a nuclear submarine and do deep sea diving! :thumbs_up:

Below the bottom picture is "click here". That will take you to a high resolution map of all of it.
Interesting where all the cables go.
I think it creates more questions than giving answers.

Thanks button MIA :cry_smile:

Back in the early days of installing the first set of TAT-8 transatlantic fiber optic cables in the 1990s, Tyco repeatedly found that the cables were being severed after installation. After several re-installs Tyco finally figured out what was going on. Sharks were biting through the cables. When asked why this was happening, one of the sharks replied, "The doc put us on a high fiber diet".

Or, just don't drop a hook anchor in the area.

LA to Mexico and LA to the Panama canal zone.
Is sea cable easier than microwave towers or land lines?
Cheaper. Overland cables require that you pay property easements enroute.
