Leveraging Dispersion-Aware Phase Recovery for Long-Haul Digital Multi-Carrier Transmission : An Experimental Demonstration

In a subcarrier multiplexing 125 Gbaud DP-PCS-64QAM system with a net bitrate of 800 Gbit/s, we numerically and experimentally study the performance of transmission-aware carrier phase estimation (CPE) for long-haul systems. The recently proposed transmission-aware dual-reference subcarrier CPE (DRS-CPE) is assessed against a more conventional per-subcarrier CPE approach and a transmission-agnostic joint CPE in 8- and 16-subcarrier transmission. At laser linewidths of ∼ 150 kHz, we achieve an experimental signal-to-noise ratio gain over a single-carrier of up to 0.5 dB after 1800 km transmission, enabled by the DRS-CPE.
