Paper Abstract

Two kinds of electronic compensation of polarization mode dispersion (PMD) are demonstrated in this paper, including transversal filter(TF) and feed forward equalizer(FFE) + decision feedback equalization(DFE). Compared with the normalized least-mean-square (NLMS), the least-mean-square (LMS) is the best algorithm to control the equalizers. The tap weights are adapted using the LMS algorithm until they reach stationary values. Then we focus on the structure of FFE+DFE and find out the relationship of the number of taps and BER with different structures in the same conditions. From the comparison, the work of 4-tap FFE+2-tap DFE is more effective, which has the most commercial value.
