China Mobile International Enhances Connectivity to North Asia with Southeast Asia-Japan 2 (SJC2) Submarine Cable

SJC2 cable to be completed in 2020

HONG KONG, March 15, 2018 /PRNewswire/ -- China Mobile International (CMI) and the members of the Southeast Asia-Japan 2 consortium (SJC2) signed an agreement with NEC Corporation to build a high performance submarine cable connecting Singapore, Thailand, Cambodia, Vietnam, Hong Kong, Taiwan, mainland China, Korea and Japan.

The latest submarine cable to be constructed by CMI, the 10,500-kilometre cable has links to eleven cable landing stations in the region and is expected to be completed by the fourth quarter of 2020.

The cable will feature up to eight pairs of high capacity optical fibre with initial design capacity of 144 Terabits per second, roughly the equivalent of simultaneously streaming 5.76 million ultra-high definition videos per second. Its high capacity allows it to support high bandwidth intensive requirements such as the Internet of Things, robotics, analytics and artificial or virtual reality applications.  

"The construction of SJC2 cable timely responded to the high broadband demand of the Southern Asia area by providing needed capacity and faster transmission, and at the same time is well prepared for the coming of 5G era. SJC2 connects from Japan all the way down to Singapore and also generates a synergy effect for our national 'Belt & Road' initiative," said Dr. LI Feng, Chairman & Chief Executive Officer of China Mobile International. "China Mobile International has invested in the construction of SJC2, and is solely responsible for two landing stations of the system respectively in Shanghai and Hong Kong. By providing dual gateway for access to China, CMI is committed to facilitating a high quality and reliable connectivity between China and the globe."

The SJC2 will be built and operated by a global consortium comprising telecommunications and technology companies, including China Mobile International; Chunghwa Telecom; Chuan Wei; Facebook; KDDI; Singtel; SK Broadband and VNPT.

CMI has over 40 terrestrial and submarine cable resources worldwide, providing 23T international bandwidth and over 138 overseas PoPs. In the future, CMI will continue to expand its global network as an industry leader. SJC2 is one of the seven planned submarine cable investments which will stretch across the world and longitudinally extend from north to south. In the coming year, CMI is expected to launch 20 more new PoPs worldwide, which will further enhance global connectivity.
