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.
