Facebook and Microsoft's Atlantic Ocean Cable Boasts Highest Capacity Ever

Tech titans are teaming up to lay 4,100 miles of cable across the Atlantic.

Construction of the cable, called MAREA, will begin in August, according to a statement from both companies, and is expected to be completed in October 2017. MAREA, which is the Spanish word for "tide," will span 4,100 miles from Virginia Beach, Virginia, to Bilbao on the northern coast of Spain.

MAREA will take a southern route away from most existing transatlantic cables, which begin in New York and New Jersey. Being separate from other cables will ensure the super high-speed cable is "more resilient and reliable," according to a blog post from Microsoft.

While the project is built on a collaboration between Facebook and Microsoft, the cable will be operated by Telxius, a unit of Telefónica, a Spanish telecommunications company. Under the agreement, Telxius will also sell capacity to other companies.
