Abstract

A system-level analysis of first-order polarization-mode dispersion (PMD) effects in a 40-Gbit/s optical system is used to compare quantitatively different electronic equalizer architectures as potential PMD compensators. It is found that a decision feedback equalizer (DFE) consisting of a 3-tap feedforward equalizer (FFE) and a 1-tap feedback equalizer (FBE) is able to increase the useful length of an optical system by more than eight times when PMD is the dominant limiting factor.
