Huawei has completed what it claims is the industry’s first live demonstration of a 600G single-wavelength ultra-high-speed transmission system.
The test saw Huawei deploy its own channel-matched saping
technology and artificial intelligence neuron module on an
optical network, with single fibre capacity of 40Tbps.
The aim of the technology is to boost network efficiency and
enable the evolution from existing traditional networking
technology to intent-driven networks, Huawei said. This would
help support deployment of new developments such as 5G, cloud
computing and big data.
Huawei shipped over 127,000 100G+ port in 2017 according to
Ovum, making up more than a third of total shipment for the
global optical networking market. With 200G networks maturing,
400G and 600G are both nearing commercialisation as demand for
ultra-high-speed optical transmission grows.
Huawei said this is the first time CMS technology has
been introduced to a transmission system, and it improves the
equivalent bandwidth of transmission links by maximising
spectral efficiency. It helped increase single-fibre capacity
by a maximum of 50% to 40T and transmission distance by
Richard Jin, president of Huawei Transmission Network
Product Line, said: "Huawei has long been leading the field of
100G, 200G, and 400G ultra-high-speed optical transmission,
thanks to our strategic investment in optical
"The new 600G system provides AI capabilities for optical
networks, using Huawei's sixth-generation coherent oDSP
algorithm and an additional optical-layer AI neuron module.
This will help our customers build intent-driven networks based
on user experience."
