Abstract :
We propose an optimum design of nonlinear compensation based on digital backpropagation assisted by mitigation with CD pre-compensation in order to reduce circuit resources. Transmission experiment with a 127Gbps PM-QPSK signal over a 2,400km SSMF line exhibits Q improvement with small stage number backpropagation and -20% CD pre-compensation.
