MARCH 27, 2008 -- Fujitsu Ltd. (search for Fujitsu) announced that it has successfully completed an upgrade of the Japan-US Cable Network, a submarine fiber-optic cable system spanning the Pacific Ocean. Fujitsu says its technology now enables the network to carry more than 1.28 Tbits/sec, doubling the original design capacity of 640 Gbits/sec.
To realize the upgrade, Fujitsu replaced legacy optical communications equipment with its FLASHWAVE S650 series in six landing points -- three each in the US and Japan. The submerged portion of the network remained unchanged. The upgrade began shortly after Fujitsu signed the contract with Japan-US CN Owners' consortium in May 2007.
The consortium represents the telecommunications carriers AT&T Corp., Cable and Wireless plc, KDDI Corp., NTT Communications Corp., Qwest Communications International Inc., Reach Global Networks Ltd., Softbank Telecom Corp., and Verizon Business.
