The SJC cable spans 8,900-kilometer, which could further extend to 9,700 kilometers when Thailand spur is connected to the system. At a project cost of around US$400 million, the SJC cable system consists of 6 fiber pairs with the initial design capacity of 28 Tbps to meet bandwidth-intensive applications such as internet TV, online games and enterprise data exchange. 

The SJC system signals a milestone for the seven Asia Pacific countries in the consortium as it will set a new benchmark in global data and information connectivity. The SJC is interconnected seamlessly with the Unity transpacific submarine cable system at the Chikura Cable Landing Station, and which together will deliver the lowest latency connectivity between Asia and the U.S., specifically from Singapore to Los Angeles.

On the other hand, the SJC cable route avoids the earthquake zone in North Asia, it enhances the operators’ network resilience by offering cable diversity and reliability in the event of a cable breakage in other undersea networks.

The SJC cable system is jointly provided by NEC and TE SUBCOM.

(CMI), China Telecommunications Corporation (China Telecom), China Telecom Global Limited (CTG, an affiliate of China Telecommunications Corporation), Donghwa Telecom Co., Ltd.
