China Telecom and Huawei Jointly Complete the Verification of a 200G+ Ultra Large-Capacity and Long-haul Transmission System

To address these challenges, Huawei provides an innovative E2E optical-electrical solution based on Flexgrid Blade OXC. It features Super 200G+ based on channel-matched shaping (CMS), special pluggable erbium-doped fiber amplifiers (EDFAs) with ultra-wide gain spectrum, Super C+L band ready Raman amplifiers, and liquid crystal on silicon (LCoS) supporting flexible slicing and ultra-low filter penalty.

Together with transmission experts from China Telecom, Huawei has recently verified the feasibility of 1:1 replication of the commercial deployment on a live network in a lab, and finally, Super 200G+ transmission over 3600 km without electrical regeneration has been achieved. The solution doubles the single-fiber capacity to 16Tbps, which can evolve to 32Tbps in the future.

"The verification project proves the performance of Huawei's Super 200G+ E2E optical-electrical solution in ultra-long haul and extremely harsh conditions," Victor Zhou, President of Huawei's Transmission Network Domain, said. "This solution doubles the transmission capacity without compromising the distance, continuously reducing the per-bit cost for operators."
