NEC: Quadruple submarine cable communication: Practical use in a few years
-Successful development of new submarine cable-
NEC:
Increases the communication area up to 4 times with the same size.
We have succeeded in developing a new submarine cable.
It is the world’s first technology, and we are aiming to put it to practical use in a few years.
New submarine cable:
conventionally,
In a glass wire with a diameter of 1/8 mm,
An optical transmission line for exchanging information,
I only got one.
This time, we increased this to four.
Submarine cable:
30 laps of the earth, 1.2 million kilometers, is spread over the Pacific Ocean and other areas.
Increasing demand for international communications:
High-speed, large-capacity communication 5G has become widespread
When it increases at a rate of 30% to 40% every year,
It is expected.
Facebook, Google, etc .:
A major American IT company is embarking on a huge investment to secure it on its own.
In addition, China is also increasing its presence by installing cables.

NEC, OCC and Sumitomo Electric complete trial of subsea cable with multicore fiber:
Tokyo, October 4, 2021,
NEC Corporation
its subsidiary OCC Corporation Sumitomo Electric Industries, Ltd.announced today that they have completed the first trial of uncoupled (*1) 4-core submarine fiber cable (*2),
and verified its transmission performance to meet the exacting demands of global telecommunications networks.
International data usage
is expected to expand by 30-40% CAGR from 2020-2026 (*3), driven by factors such as the growth of 5G mobile data, and the need to share ever more content between data centers distributed around the world.To meet this demand,
submarine networks are adopting space division multiplexing (SDM) technology, where the number of independent spatial channels is increased to maximize total system capacity, reduce power consumption and optimize cost per bit.Multicore fiber
is now expected to further increase the number of parallel optical fiber cores without increasing the submarine cable size and structure, enabling the second generation of submarine SDM systems.Press Releases | NEC
