Three companies - Microsoft, Facebook and Telxius - jointly
laid a fiber optic cable called Marea across the Atlantic: from American Virginia to Bilbao, Spain. The capacity of Marea is 160 Tbps. This is the
most high-performance transatlantic cable today.
The cable length is 6600 kilometers, and the average depth is 3.35 kilometers. Marea was laid in less than two years, while the standard period for such projects is about five years.

The first wire that people laid across the ocean was the
transatlantic telegraph cable . The first attempt was made in 1857, but the cable broke.
On August 5, 1858, a cable was laid between the islands of Valentia and Newfoundland, but already in September it failed. The long-term connection between Europe and America was provided only by a cable laid in 1866.
The first
telephone cable across the Atlantic Ocean appeared in 1956, although it was discussed back in the 1920s. Since then, mankind has
built a huge number of underwater communication channels. They did not reach only Antarctica, they go to the Internet through satellite connection.

the fastest .
Formally, FASTER remains the fastest cable and now Marea
will be used only in the beginning of 2018. He will reveal his full potential in 2025. It is expected that by this time global traffic consumption will increase eight times.
In the conditions of such growth, a new cable is
needed by Microsoft and Facebook in order to ensure the stable operation of their services. Microsoft President Brad Smith (Brad Smith) has already
spoken about the importance of Marea:
“Marea was laid on time. 55% more data passes through transatlantic cables than through Pacific cables. And 40% more than the cables connecting the USA and Latin America.
Of course, the flow of data across the Atlantic Ocean will grow, and Marea will provide the necessary connection quality for the USA, Spain and other countries. ”
Another
reason why the companies initiated the project is natural disasters. In 2006, a seven-point earthquake occurred on the island of Taiwan, which caused eight cables to connect the island with China. To restore them, it took 11 ships and 49 days. And in 2012, Hurricane Sandy left without communication the East Coast of the United States. From this point on, Microsoft decided to increase the resiliency of transatlantic connections. It turns out that Sandy just united Facebook and Microsoft.
“We constantly met with representatives of Facebook at various events and realized that we were trying to solve the same problem. Therefore, we have united and improved the transatlantic network, having designed a new cable, ” said Frank Ray, head of the infrastructure direction for cloud solutions.
Marea
consists of eight pairs of fiber-optic cables protected by copper, plastic and a waterproof coating. On most of the way, the cable lies at the bottom of the ocean, and is buried under the ground near the shores so that ships will not tear it. So
it was in 2012, then for the month two different vessels damaged the cable connecting East Africa with the Middle East and Europe.
The community understands that the submarine cables are not without drawbacks, therefore, it is developing alternative connection methods. Mark Zuckerberg
suggests using drones, AT & T uses electric networks, and some scientists use quantum teleportation. However, these projects are in the early stages of their development or
exist so far only on paper.
