Abstract

600Gb/s-PM-64QAM coherent transmission performances over 101km SMF with distributed Raman amplification of different pumping schemes are investigated. While forward pump using FP-laser diode can introduce 0.9dB Q-margin, hybrid forward/backward pumping can further optimize system performance.
