Mitsubishi Electric Cor. (TOKYO:6503) says it has won a contract to upgrade the DWDM capacity of the transatlantic TAT-14 Cable Network to 40 Gbps per wavelength. The company expects to complete the two-phase upgrade, which will expand the fiber-optic network’s capacity 7X, by the fourth quarter of 2012.
TAT-14 comprises more than 15,000 km of fiber-optic cable and connects seven landing stations in the North Atlantic. It was commissioned in 2001 with a 10-Gbps DWDM system. The seven carriers in the consortium that owns the undersea fiber optic network include Abovenet Communications, Inc., AT&T Corp., Deutsche Telekom AG., France Télécom S.A., KPN B.V., TeliaSonera AB (publ)., and Verizon.
According to Muneo Abe, general manager of Mitsubishi Electric’s Telecommunication Systems Department, “Upgrading a 10-Gbps transatlantic cable to 40 Gbps is unprecedented, and this upgrade marks a significant milestone for Mitsubishi Electric. We have completely verified our 40-Gbps technology from field trials conducted over a transatlantic segment.”
