Southeast Asia-Japan submarine cable to improve latency, resiliency

The US$400 million system which links seven countries in Southeast Asia to the latest transpacific cable, will deliver faster connectivity and offer better resiliency with its route avoiding the earthquake zone in North Asia.

The Southeast Asia-Japan Cable (SJC) system, is now up and running, aimed at offering a more resilient and cost effective option for operators to meet the region's growing bandwidth requirements.

The US$400 million SJC cable system links the seven countries or territories of Brunei, China, Hong Kong, Japan, Singapore and the Philippines, including the option to link with Thailand, according to a press release on Thursday. 

The system consists of six fiber pairs with the initial design capacity of 28 Terabits per second to meet bandwidth-intensive applications such as Internet TV , online games and enterprise data exchange. For example, it is capable of supporting simultaneous streaming of up to 3 million high-definition videos.

Ooi Seng Keat, spokesperson for the SJC consortium and SingTel's vice president for Carrier Services International Business Unit for Group Enterprise said the SJC system will set a new benchmark in global data and information connectivity .

"The SJC is interconnected seamlessly with the latest transpacific cable, and which together will deliver the lowest latency connectivity between Asia and the U.S., specifically from Singapore to Los Angeles. As 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," Ooi said.

The SJC is an 8,900km cable system, extendable to 9,700km. It's operated by a global consortium of telecommunications and technology companies comprising Brunei International Gateway (BIG), China Mobile International (CMI), China Telecom, China Telecom Global, Donghwa Telecom, Globe Telecom, Google, KDDI, SingTel, Telekomunikasi Indonesia International, and Thailand's TOT.
