Abstract

The performance of penalty compensation in 40G bit/s Non-Return-to-Zero (NRZ) systems that use nonlinear adaptive decision-feedback equalizer (ADFE) based on least mean squares (LMS) arithmetic is demonstrated in this paper. There is remarkable performance improvement of dispersion tolerance in single channel 40G bit/s NRZ systems by comparing the 1dB eye-opening penalty (EOP) after the ADFE is introduced. The PMD tolerance limit is improved from 0.17/bit slot of before equalization to 0.22/bit slots, when the system outage probability of tolerant (@BER>10^-9) is 10^-3.
