New company formed to construct largest trans-Pacific submarine cable

It will start operations by the end-2024.

A new company, Seren Juno Network Co., Ltd (Seren), has been founded to construct and operate the new and largest trans-Pacific submarine cable system between Japan and the US with a maximum capacity of 350 terabytes per second.

The project, which is expected to begin operations at the end of 2024,  is led by NTT Ltd. Japan Corp., Mitsui & Co., Ltd., PC Landing Corp., JA and JA Mitsui Leasing, Ltd. The planned landing site is in Chiba and Mie prefecture in Japan and in California in the USA which has around a 10,000-kilometre distance.

In a statement, NTT said the JUNO project will introduce space division multiplexing technology, allowing the provisioning of 20 optical fibre pairs per cable. 

It also offers resiliency with the Japan-US connection, providing additional security against any potential disturbances because of rough weather conditions. The project also provides flexibility as it can change the amount of bandwidth to each branch route according to demand.

Seren, meanwhile, will provide network services such as sales, operations and management support to major global technology companies, over-the-top Communications, and telecommunication carriers.

“With the rapid growth of the global digital economy and an increasing demand for cloud solutions and lower latency, the undersea internet cable sector is quickly becoming more critical to global internet infrastructure,” said NTT President and CEO Takanobu Maeda. “This new subsea cable is the latest joint effort NTT has led in a long and proud history of providing reliable global internet infrastructure.”

NTT cited data from telecommunications industry analyst firm TeleGeography that global internet bandwidth has increased by 29% in 2021, and is expected to continue its rise due to the deployment of 5G, internet-of-things, and edge compute technologies.
