NEC to build “SJC2” fiber optic submarine cable


NEC announced that it will build a large-capacity optical fiber submarine cable linking Japan, South Korea, China, Taiwan, Hong Kong, Vietnam, Thailand, Cambodia, and Singapore with the name “SJC2 (Southeast Asia-Japan Cable 2).” The members of the alliance that have concluded the contract for the construction of this project include eight international telecommunications companies such as KDDI Corporation of Japan (Note 1). “SJC2” is expected to be completed by 2020.

The total length of the “SJC2” fiber optic submarine cable is approximately 10,500 kilometers. Using the latest technology of 100 Gbps optical wave multiplex transmission at each wavelength, the design capacity can reach up to 144 Tbps (Note 2) per second.

The “SJC” optical fiber submarine cable (Note 3) currently in operation, together with the laying of this cable, will be able to respond to AI (Artificial Intelligence), IoT (Internet of Things), VR (Virtual Reality) and other high-frequency broadband services. To meet the communication needs of Southeast Asian and East Asian countries, the “SJC2” fiber optic submarine cable will be an important backbone for promoting digitalization and technological innovation, and is expected by all circles.
