“…To cope with rapidly increasing data traffic, technologies for beyond-100 Gbps (B100G) transmission have been intensively developed. We recently reported on successful field trials of 400-Gbps transmission [1,2]. As well as B100G, using multiple bands (e.g.…”

Dual-carrier 400-Gbps channels in C+L-band are transmitted over dispersion shifted fiber (DSF) in field for the first time. Distributed Raman amplification not accompanied by EDFA (all-Raman amplification) is used to suppress the nonlinear distortions, which strongly occur in the zero-dispersion region in C-band. The transmitted distance is 200 km and the maximum distance is expected to be 480 km, while the Raman pump power is lower than a safety level for commercial use. The field experiment demonstrates that all-Raman amplification is feasible for effective use of existing DSF links in regional optical networks.
