Paper Abstract

Numerical simulations have been conducted to investigate the performance of a transmission system in which high spectral-efficiency duobinary modulation format is combined with adaptive electrical equalizer. The conventional filter parameters and the optimum filter parameters are used for comparison of system performance with and without adaptive linear equalizer (ALE). Numerical simulation results show that the dispersion tolerance and nonlinear tolerance (@1 dB EOP penalty) are effectively improved by ALE for duobinary NRZ (DNRZ) with conventional filter parameters, but it is not obvious for DNRZ with optimum filter parameters.
