Very interesting information on how to created a worldwide network - the Internet, how the relationship between the different continents of our planet, as laid fiber optic cable on the ocean floor and has a lot of interesting facts. I advise you to reading everything.
He is 69 millimeters in diameter, and that it carries 99% of all international traffic connection (ie Internet, telephony and other data). He connects all the continents of our planet, with the exception of Antarctica. These amazing optical fiber cables cross the oceans, and they are hundreds of thousands of long, what to say, millions of miles away.

This is the "CS Cable Innovator", it's specially designed for fiber-optic cable and is the largest of its kind in the world ship. It was built in 1995 in Finland, it is 145 meters long and 24 meters wide it is. It is capable of carrying up to 8,500 tons of fiber-optic cable. The ship has 80 cabins, 42 of them - officers cabins, 36 - Crew cabins and two cabins of luxury.
No maintenance and refueling work, he can 42 days, and if it is accompanied by support ship, all 60.
Originally, submarine cables were simple point-to-point. Now the submarine cables are more complex and they can share and fork right on the ocean floor.
Since 2012, the provider was successfully demonstrated the underwater data transmission channel with a capacity of 100 Gbit / s. It stretches across the entire Atlantic Ocean and the length is 6000 kilometers. Imagine that three years ago meatlanticheskogo bandwidth communication channel was 2.5 times smaller and is equal to 40 Gbit / s. Now the ships like "CS Cable Innovator" constantly working in order to provide us with all the rapid intercontinental Internet.

Here's how it looks like on the bottom. What are the environmental consequences of laying telecommunication cables on the seabed? How does this affect the bottom of the ocean and the animals that live there? Although literally millions of kilometers of cable ties were placed on the bottom of the sea over the last century, it had no impact on the lives of underwater creatures. According to recent research, the cable has only minor effects on the animals living on and within the seabed. In the picture above we see a variety of marine life near the undersea cable that crosses the continental shelf of Half Moon Bay.
Then the cable is only 3.2 cm thick.
Many feared that the load cable TV channels, but in fact it increased the pressure by only 1 percent. Moreover, cable television, which can go on underwater fiber already has a bandwidth of 1 Terabit, while satellites give 100 times less. And if you want to buy yourself a transatlantic cable, then it will cost you $ 200-500 million.
