Huawei and Orange achieved a new world record of 157 Tbit/s transmission prototype testing over a 120 km fiber

You will be glad to know that Huawei and Orange have successfully achieved a new world record1 of 157 Tbit/s transmission prototype testing over a 120 km fiber on the Orange network in South West France.

In June 2022, the Chinese tech giant Huawei released the industry’s first ultra-broadband Super C + Super L solution able to provide 12 THz of spectrum over a fiber using C band (C for Conventional wavelengths) and L band (L for long wavelengths).

In this testing, the total bandwidth was extended to 18 THz by using in-house technologies for S band (S for short wavelengths) and relying on the transmission expertise of Huawei’s French R&D Center. A total number of 240 wavelengths were used to provide a total transmission capacity of 157 Tbit/s, based on Huawei’s advanced high-order constellation shaping modulation algorithm.

Gilles Bourdon, Vice President for Wireline Networks & Infrastructure, Orange Innovation, declared: “Facing the continuous increase of traffic demand, obtaining more spectrum and therefore more value from our existing assets is crucial. It is even more important as spectral efficiency of such optical systems reaches a theoretical limit. The testing proves the capability of our fiber infrastructure to offer 50 % more spectrum and thus effectively address one of our key topics: the experience and connectivity of our customers.”

Richard Jin, President for the Optical Business Product Line, Huawei, declared: “Huawei has long been committed to strategic investments, research and technological breakthroughs in the optical communications domain, as illustrated by the excellence of our optical research teams, such as the one in Paris. We are delighted to collaborate with an operator as innovative as Orange to contribute, together, to the creation of the network of the future.”
