Facebook has teamed up with Microsoft to build an undersea internet cable, which runs from the US to Spain. The fibreoptic cable dubbed Marea, meaning ‘Tide’ in Spanish, is expected to stretch from Virginia on America’s east coast to Bilbao, in the Basque Country, across around 4,100 miles of seabed. After which data passing through the cable will then be shuttled forward through existing links to other continents such as Africa, Asia, the Middle East, and the rest of Europe.

The cable will feature a bandwidth of 160 terabits per second, According to The Independent that’s “Around 8.5 million times more than the average UK home internet connection”. While announcing the project, Microsoft global network director Frank Rey said:

We’re seeing an ever-increasing customer demand for high speed, reliable connections for Microsoft cloud services, including Bing, Office 265, Skype, Xbox Live and Microsoft Azure.

“As the world continues to move towards a future based on cloud computing, Microsoft is committed to building out the unprecedented level of global infrastructure required to support ever faster and even more resilient connections to our cloud services.”

The cable will be operated and managed by Telxius, a firm owned and controlled by Spanish telecoms giant Telefonica. Although It’ll be able to sell access to the cable to other companies, Facebook and Microsoft will get the best treatment, and also a better share of the available bandwidth. This kind of capacity will help the two companies improve the speed and reliability of their services also with this both companies will be able to move vast amounts of data across the world more easily.

It will be up and running at the end of 2017, once this is completed, it’ll be the highest-capacity cable in the Atlantic Ocean.
