Construction on the Marea cable has started : the highest-capacity sub-sea cable ever placed across the Atlantic, and the first to connect the U.S. to southern Europe. Construction started in August, with completion scheduled for October 2017. Bloomberg news reports that cables have been laid on the ocean floor for a long, long time : the first trans-Atlantic telegraph cable in 1866. The Marea cable will be paid for by Microsoft and Facebook, and be able to carry up to 160 Terabits per second of data.
