Facebook and Nokia have found a way to push a lot more data through a submarine cable across the Atlantic, which could help the social network keep up with the growth of video and virtual reality.
On a 5,500-kilometer (3,400-mile) cable between Ireland and New York, the companies tested a new technique developed at Nokia Bell Labs for increasing the efficiency of fiber-optic cables. They say it comes close to the absolute limit for sending bits over a fiber.
Facebook CEO Mark Zuckerberg has said VR is the future of social media. If it is, then the networks that link consumers and data centers will have more data than ever to carry. Higher resolution video also is increasing the burden on networks. For example, Netflix recommends subscribers have at least a 5Mbps broadband connection to stream HD video and 25Mbps for Ultra HD (4K) streams.
