Submission + - Facebook invests in 55-terabit intra-Asia submarine cable system (extremetech.com) 1
MrSeb writes: "Facebook has joined a consortium that will build by far the fastest intra-Asia submarine fiber optic network, the Asia Pacific Gateway (APG). Facebook is the only American company involved with the venture, which will see 10,000km (6,000 miles) of prime fiber laid between Malaysia and Japan (pictured above), with branches landing in almost every country along the way (Singapore, Thailand, Vietnam, China, Taiwan, and South Korea). When the cable goes online in 2014, at a cost of around $450 million, it is slated to use 40Gbps channels, for a total capacity of 55 terabits per second, or a transfer speed of 6.9 terabytes (138 Blu-ray discs) per second. When the various routers and repeaters are upgraded to 100Gbps-per-channel, the cable will have a total capacity of well over 100Tbps. The prime reason for building the cable, other than making money, is to provide more redundancy between the US and Asia. Currently, almost every connection from Asia to the US is routed through Singapore or Japan. If there is congestion at one of these sites, or a cable is cut, then the other (highly populous) countries in south east Asia are in trouble. It is perhaps no surprise that China Telecom and China Unicom, two of the world’s largest telecoms companies, are involved in the laying of APG. Facebook's involvement is almost certainly due to the fact that the social network's growth has almost stagnated in Europe and North America, while Asia is only just starting to climb on the Facebook bandwagon."
