NEC has won a contract from Okinawa Cellular Telephone Company to supply an optical submarine cable system connecting Okinawa Prefecture and Kagoshima Prefecture in Japan to be in operation in April 2020. 

A press release said that NEC will provide the optical submarine cable system as a turnkey solution. The cable will be manufactured by NEC’s subsidiary OCC Corporation, which it noted is the only company in Japan that can make optical submarine cables capable of withstanding the water pressure from 8,000 m deep seas.

The cable system will be connected to Nago City, Okinawa Prefecture, and Hioki City, Kagoshima Prefecture, with a total length of approximately 760 km and at a maximum depth of approximately 1,200 m. The system will employ the latest optical wavelength multiplex transmission method, with maximum design transmission capacity of 80 Tbps.

NEC, as a system integrator, will provides all aspects of submarine cable operations, including the optical transmission terminal stations, optical submarine repeaters, optical submarine cables, ocean surveys and route designs, installation of equipment and cable, and training and delivery testing.
