Paper Abstract

Compared to other digital equalizers, MLSE (maximum likelihood sequence estimator) equalizer seem to be the most promising candidate solution to mitigate impairments caused by CD, PMD and fiber's nonlinearity. A novel MLSE equalizer technology combined with FFE based on nonlinear Volterra theory is investigated, which shows superior performance for joint compensation of all distortion effects in uncompensated 40Gbit/s Pol-Mux RZ-DQPSK optical transmission system. The receiver can achieve a long haul transmission with 280 km without any optical dispersion compensation.
