As of July 2016, the world's highest-capacity undersea Internet cable runs between which two countries?

The world’s highest-capacity undersea internet cable, a 5,600-mile link between the US and Japan backed by Google was activated on 30 June 2016. The fibre cable, which can transport data at 60 terabits per second (60 million Mbps) is expected to be a significant boost to trans-pacific Internet speeds. Google is one of six companies behind the project, alongside Asian telecoms groups. According to Google’s Urs Holzle this link has more capacity than any other active subsea cable. The $300m Faster cable system will connect to hubs in Los Angeles, San Francisco, Portland and Seattle, and two points in Japan.

Google is also backing a project to build a cable between Florida and Brazil due to be finished by the end of 2016, while Microsoft and Facebook recently announced a trans-Atlantic cable between Virginia Beach and Bilbao in Spain.
