Mitsubishi Electric to Upgrade Transatlantic Cable Network


Mitsubishi Electric has signed a contract to provide a 40 Gbps dense wavelength division multiplexing (DWDM) capacity upgrade to an existing transatlantic submarine cable network. The TAT-14 Cable Network, owned by a consortium of major telecommunications carriers, comprises over 15,000 km of fiber-optic cable linking seven landing stations in the North Atlantic region, and was originally supplied in 2001 with a 10 Gbps DWDM system. In order to satisfy the need for increased capacity, Mitsubishi Electric proposed to apply its latest high-speed fiber-optic technologies to upgrade this system with its 40 Gbps DWDM technology.


Mitsubishi Electric expects to complete the two phase upgrade to the TAT-14 Cable Network by the fourth quarter of 2012, enabling the network’s maximum capacity to be increased sevenfold
