The Kitadaito Island submarine cable is a 410 km optical WDM, repeatered system that connects two landing points in Japan: Kitadaito and Yaese. The cable was completed in 2022 and is operated by Okinawa Prefecture.
Japan:
The cable is owned and operated by Okinawa Prefecture.
The Kitadaito Island submarine cable uses Optical WDM technology with repeaters. It was manufactured and installed by NEC and its subsidiary OCC Corporation.
The Ready for Service (RFS) year of the Kitadaito Island submarine cable is 2022. The exact status beyond this point is unknown.
This cable connects two points in Japan, specifically Kitadaito and Yaese. These locations are part of Okinawa Prefecture, which includes several islands in the Ryukyu Islands chain east of mainland Japan. The connection enhances telecommunications infrastructure for these remote areas.
Kitadaito Island is one of the smaller islands within Okinawa Prefecture, known for its military installations and limited civilian population. Yaese, on the other hand, is a more developed area with significant economic activities, including fishing and tourism. The cable enhances communication capabilities in these regions, supporting both local needs and broader national telecommunications networks.
The Ryukyu Islands, of which Okinawa Prefecture is a part, are strategically important due to their location between the Asian mainland and the Pacific Ocean.
