"From Japan to Singapore": a new submarine cable will pass through 9 countries in Asia
The consortium Southeast Asia-Japan 2 has signed an agreement with the Japanese manufacturer of telecommunications equipment NEC Corporation for laying the SJC2 submarine cable with a capacity of 144 Tbit / s. The cable will connect nine countries.

The length of the cable will be 10.5 thousand km - it will connect Japan, South Korea, mainland China, Taiwan, Hong Kong, Thailand, Cambodia, Vietnam and Singapore.
SJC2 will consist of eight fiber optic pairs. With a bandwidth of 144 Tbps, the data transfer rate for each pair will be 18 Tbps. The project is scheduled for completion by the fourth quarter of 2020. The cost of SJC2 has not yet been disclosed , but it is known that 400 million dollars have been 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 Lynette Lee (Linette Lee) believes that building SJC2 is a key stage in Asian cooperation in digital technology. A new, more powerful cable will complement its predecessor, the initial design capacity of which was only 28 Tbit / s. The cabling system will help ensure uninterrupted communication and reduce delays for companies in an economically active region and their customers.
Yu Cheng, one of the representatives of Taiwanese operators, chairman and CEO of telecommunications company Chunghwa Telecom, claims that the SJC2 cable will help the organization ensure the work of many multimedia applications when launching 5G services in 2020.
From the project executor, NEC, Atsuo Kawamura gave a comment. He emphasizes that SJC2 will allow to cope with the subsequent growth of bandwidth requirements in the region.
It can be assumed that NEC was not assigned 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, which connected China, Hong Kong, Japan, South Korea, Malaysia, Taiwan, Thailand, Vietnam and Singapore. The APG data transfer rate is 54 Tbps.
In May 2017, the organization's specialists managed to transfer data over an undersea cable with a length of 11 thousand km at a speed of 50.9 Tbit / s (one optical fiber each). Scientists used an optimized opt32 modulation algorithm that allowed spectral efficiency of 6.14 bit / s / Hz. In this case, they used erbium-doped (EDFA) fiber-optic amplifiers.
And in 4Q2019, the NEC plans to complete the laying of a cable system that will connect Hong Kong and Guam. Its length will be 3900 km, and its throughput - 50 Tbit / s.

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

Why did you need a cable
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.
