Abstract :
We have experimentally investigated the characteristics of 128 Gb/s DP-QPSK signals received with two types of nonlinear equalizers (NLE) followed by soft-decision (SD) FEC. With experiments, we demonstrate that the optimization of parameters for NLEs enables the successful cooperation of SD-FEC and NLEs after nonlinear transmission.
