Orange, Huawei transmit 157 Tbps over 120 km
Huawei says it has partnered with Orange on an optical transmission trial that saw 157 Tbps over a 120-km fiber link on the Orange’s network in Southwest France. The demonstration, results of which the collaborators believe is a world record, leveraged the C-, L-, and S-Band.
The trial used a prototype implementation of Huawei’s Super C + Super L transport technology announced this past June. While that technology is designed to provide 12 THz of transmission spectrum, Huawei and Orange added S-Band capabilities enabled via Huawei's French R&D Center to create 18 THz of spectrum. The collaborators then transmitted 240 wavelengths to create a total transmission capacity of 157 Tbps, enabled via Huawei's high-order constellation shaping modulation algorithm.
"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," commented Gilles Bourdon, vice president for wireline networks and infrastructure at Orange Innovation.
