Huawei, BT Ireland conduct 1.2-Tbps live network trial

Dec. 5, 2019
The 1.2-Tbps trial occurred over a link between a pair of data centers in Dublin.

Huawei says it has collaborated with BT Ireland to conduct a trial of 1.2-Tbps optical transmission based on a commercial product platform over a live network. The 1.2-Tbps trial occurred over a link between a pair of data centers in Dublin.

The system involved leveraged Huawei’s OptiXtreme series oDSP coherent transmission chips (see "Huawei introduces 400G optical network technology for commercial use"). The oDSP chips use channel-matched shaping as well as what Huawei calls “AI neuron modules.” The modules sense optical channel parameters and compensate for link impairments to optimize the transmission spectrum efficiency, according to the company. The transmission platform also used Huawei’s “Super-C” technology, which transmits across a spectrum window that slightly exceeds the C-Band. Super-C can enable a total transmission capacity of 48 Tbps, Huawei asserts.
