The 10,500km cable, which is expected to be completed by the end of 2020, will be capable of transmitting data at 144 terabits per second, roughly the equivalent of simultaneously streaming 5.76 million ultra-high definition videos per second.
The cable will have up to eight fibre pairs of high-capacity optical fibre. It will be capable of supporting high bandwidth intensive requirements such as the Internet of Things, robotics, analytics and artificial or virtual reality applications.
Linette Lee, chairperson of the SJC2 consortium and director, Submarine Cable Investments at Singtel's Carrier Services, International Business Unit, Group Enterprise, said, "The construction of SJC2 cable marks a key milestone in intra-Asian digital collaboration. The newer and higher capacity cable complements the earlier SJC which was completed in 2013.
The SJC2 will be built and operated by a global consortium comprising telecommunications and technology companies, including China Mobile International; Chuan Wei; Chunghwa Telecom; Facebook; KDDI; Singtel; SK Broadband; and VNPT.
"NEC is honoured to be selected by the SJC2 consortium as the supplier for the most advanced optical fibre submarine cable system, landing at 11 locations across nine countries and regions," said Atsuo Kawamura, NEC's senior vice-president, Telecom Carrier Business Unit.
"SJC2 is designed so that once completed, it can carry at least 18Tbps of capacity per fibre pair. The robust and flexible design will enable SJC2 to cope with future changes in capacity demands.
"SJC2 will provide seamless connectivity and network diversity, while serving to complement other intra-Asia submarine cables, among others, such as the original SJC built in 2013."
