scoop
Tata Communications, Huawei and
Huawei Marine have revealed the
successful completion of a 400G field
trial on a subsea network over 6,000km.
The test results demonstrated an optical
transmission of 400G signals, believed to
be an industry first for a submarine cable
system of this length.
Huawei and Huawei Marine’s technical
solution adopted the modulation format
of dual carrier polarisation division
multiplexing quadrature phase shift keying
(DC-PDM-QPSK), a faster-than-nyquist (FTN)
compensation and recovery algorithm,
proprietary clock recovery technology
and soft decision forward error correction
(SD-FEC) technology to address the
problems of high speed signal distortion
and unstable clocks.
Mr Hon Kit Lam, vice president,
international transmission and IP business,
Tata Communications, said: “The 400G
technology of Huawei and Huawei Marine
demonstrates that our existing subsea
network asset is capable of supporting
future, next-generation transmission
technology as shown in the 400G trial.”
