Signal power asymmetry optimisation for optical phase conjugation using Raman amplification  
Description:
We numerically optimise in-span signal power asymmetry in different advanced Raman amplification schemes, achieving a 3% asymmetry over 62 km SMF using random DFB Raman laser amplifier. We then evaluate the impact of such asymmetry on the performance of systems using mid-link OPC by simulating transmission of 7×15 Gbaud 16QAM Nyquist-spaced WDM-PDM signals.
