NEC to build new trans-Pacific cable to provide largest data capacity between the US and Japan
NEC Corporation has been contracted by Seren Juno Network Company to build a trans-Pacific subsea fibre-optic cable connecting California with Chiba prefecture and Mie prefecture in Japan .
The JUNO Cable System will provide the largest data capacity between the US and Japan , spanning a total distance of approximately 10,000km and is expected to be completed by the end of 2024 .
Until recently , subsea cable was composed of 16 fibre pairs at most , but currently , by using NEC ’ s newly developed energy efficient repeaters and the leading-edge SDM ( Space Division Multiplexing ) technology , this system will be able to adapt as many as 20 fibre pairs for the first time in a trans-Pacific subsea fibre-optic cable .
The cable is expected to provide a maximum capacity of 350Tbps , the largest among any existing cable system between the US and Japan .
JAPAN PLAYS AN IMPORTANT ROLE AS A DATA HUB IN THE ASIA- PACIFIC REGION .
Japan plays an important role as a data hub in the Asia-Pacific region . This cable will promote the development of digital economies by supporting the strong demand for communications , including the spread of 5G throughout Asia and North America .
In addition , by providing communication routes from two separate locations in Japan to the US , the system will be highly resilient to natural disasters in the coastal areas of Japan .
Moreover , the WSS ( Wavelength Selective Switch ) function will enable the system to remotely alter the bandwidth of each route , enabling it to respond flexibly to customer business needs and changes in communications traffic demand .
NEC has been a leading supplier of submarine cable systems for more than 50 years and has built more than 300,000 km of cable , spanning the earth nearly eight times .
NEC is well-established as a reliable partner in the submarine cable field as a system integrator that provides all aspects of submarine cable operations , including the manufacture and installation of optical submarine cables and repeaters , provision of ocean surveys and route designs , training and delivery testing .
NEC ’ s subsidiary OCC Corporation manufactures subsea optical cables capable of withstanding water pressures at ocean depths beyond 8,000 metres . �
