Fujitsu has announced that it has signed the contract for the upgrade of the Japan-US Cable Network, a submarine fiber-optic cable system, with a consortium represented by seven telecommunications carriers, including AT&T Corp, KDDI Corporation, NTT Communications Corporation, Qwest Communications International Inc., Reach Global Networks Ltd, Softbank Telecom Corp., and Verizon Business. With this transpacific contract, Fujitsu’s  submarine line terminal equipment will be implemented at three landing points each in Japan and the US. The equipment is capable of providing a significant capacity upgrade to existing systems, more than doubling the original design capacity of 640 gigabits per second (640 Gbps) of the Japan-US Cable Network beyond 1.28 terabits per second (1.28 Tbps).
