Keywords:Optical signal processing techniques for optical communications, Transmission impairments and their mitigations

We demonstrate transmission reach enhancement by nonlinearity mitigation in a Raman-amplifier-based transmission link by utilizing a CSI-OPC device multiple times, which causes less Q-factor degradation in a linear regime, using 22.5-Gbaud PDM-16QAM 10-channel DWDM signals.
