NEC says it has signed an agreement with the Southeast Asia--Japan 2 consortium to build a new submarine cable system to complement the existing SJC cable. The SJC2 cable will stretch 10,500km from Singapore to Japan, hooking up Thailand, Cambodia, Vietnam, Hong Kong, Taiwan, mainland China, and Korea along the way.
The plan is for eight fiber pairs and an initial design capacity of a whopping 144Tbps, or 18Tbps per fiber pair. That's a lot of bandwidth between North and Southeast Asia by any measurement, and represents some long term thinking by the region's tech and telecom players as they plan for IoT, AI, 5G, virtual reality, and whatever else might be coming down the pike toward them.
The target date is Q4 of 2020, assuming all goes well. The SJC2 consortium includes China Mobile International, Chuan Wei, Chunghwa Telecom, Facebook, KDDI, Singtel, SK Broadband, and VNPT.
