March 24, 2018 at 19:17“From Japan to Singapore”: New Submarine Cable Passes Through 9 Asian Countries
The Southeast Asia-Japan 2 consortium has signed an agreement with Japanese telecommunications equipment manufacturer NEC Corporation to lay an SJC2 submarine cable with a throughput of 144 Tbit / s. The cable will connect nine countries.

The cable will be 10.5 thousand km long - it will connect Japan, South Korea, mainland China, Taiwan, Hong Kong, Thailand, Cambodia, Vietnam and Singapore.
SJC2 will consist of eight fiber pairs. With a throughput of 144 Tbit / s, the data transfer rate for each pair will be 18 Tbit / s. The project is planned to be completed by the fourth quarter of 2020. The cost of SJC2 has not been disclosed , but it is known that $ 400 million was invested in the previous cable (SJC).
SJC2 will complement the SJC, which was laid in 2013. SJC and SJC2 will “intersect” in China, Hong Kong, Japan, Singapore and Thailand, but the second cable will connect new countries: Cambodia, South Korea, Vietnam and Taiwan.
SJC2 Chairman Linette Lee believes that building the SJC2 is a key step in Asian digital collaboration. New, more powerful cable will complement its predecessor, the original design capacity of which was equal to a total of 28 Tbit / s. The cable system will help ensure uninterrupted communication and reduce delays for companies in the economically active region and their customers.
One of the representatives of Taiwanese operators, chairman and CEO of the telecommunications company Chunghwa Telecom, Yu Cheng , claims that the SJC2 cable will help the organization ensure the work of many multimedia applications when launching 5G services in 2020.
On the part of the project executor, NEC, the comment was given by Atsuo Kawamura. He emphasizes that SJC2 will cope with the subsequent increase in bandwidth requirements in the region.
It can be assumed that NEC was not appointed to this project by chance - its employees have extensive experience in implementing such projects.
In November 2016, the company completed the Asia-Pacific Gateway (APG) submarine cable that connected China, Hong Kong, Japan, South Korea, Malaysia, Taiwan, Thailand, Vietnam, and Singapore. The APG data rate is 54 Tbps.
In May 2017, the organization’s specialists managed to transfer data via an underwater cable with a length of 11 thousand km at a speed of 50.9 Tbit / s (one optical fiber). Scientists usedoptimized opt32 modulation algorithm, which allowed to obtain a spectral efficiency of 6.14 bit / s / Hz. In doing so, they used erbium-ion doped (EDFA) fiber optic amplifiers.
And in the 4th quarter of 2019, NEC plans to finish laying the cable system that will connect Hong Kong and Guam. Its length will be 3900 km, and its throughput capacity is 50 Tbps.

In the second quarter of 2018, the Trident project will be completed . This submarine cable will connect Singapore, Indonesia and Australia. Its throughput will be 28 Tbps.
Another cable, Hawaiki, will connect Australia and New Zealand with Hawaii and the US west coast by mid-2018. The total length of the cable will be 14 thousand km, and the throughput is 30 Tbit / s.
Another project to be completed this year is the Bay of Bengal Gateway ( BBG ) cabling system . It will unite Singapore, Malaysia, India, Sri Lanka, Oman and the UAE.
