The SJC2 consortium announced with NEC Corporation the completion of construction and the start of operations for the Southeast Asia-Japan Cable 2 (SJC2), a high-capacity optical submarine cable connecting the Asia region.SJC2’s main trunk links Singapore, Hong Kong China, and Japan, with additional branches covering other key Asia-Pacific countries and regions. Constructed by NEC, the cable spans a total length of approximately 10,500 kilometers and employs the latest optical wavelength division multiplexing technology, which is capable of transmitting more than 126 terabits per second (Tbps).SJC2 enhances submarine cable infrastructure in the region with additional capacity, route diversity, and resilience by strengthening the redundancy of the network
