NEC To Build Submarine Cable System For Okinawa Cellular
18 Feb 2019
NEC has won a contract from Okinawa Cellular Telephone Company to design, engineer, supply, install, test and implement an optical submarine cable system connecting Okinawa Prefecture and Kagoshima Prefecture in Japan. NEC will provide the optical submarine cable system as a turnkey solution. This cable system is scheduled to start operation in April 2020.
This cable system is connected to Nago City, Okinawa Prefecture, and Hioki City, Kagoshima Prefecture, with a total length of approximately 760 km and a maximum depth of approximately 1,200 m. The cable system employs the latest optical wavelength multiplex transmission method, and the maximum design transmission capacity is 80 Tbps.
NEC, as a system integrator, provides all aspects of submarine cable operations, including the production of optical transmission terminal stations, optical submarine repeaters, optical submarine cables, ocean surveys and route designs, installation of equipment and cable installation, and training and delivery testing. NEC's subsidiary, OCC Corporation, is responsible for the manufacture of this cable, which is the only company in Japan that can manufacture optical submarine cables capable of withstanding the water pressure from 8,000 m deep seas.
