Paper Abstract

The performance of 10Gb/s or above optical single channel transmission system is mainly limited by the chromatic dispersion (CD) and polarization mode dispersion (PMD) effect, and hence, different modulation formats and equalization methods are required to increase transmission distance, and mitigate transmission impairment. In this paper, we numerically evaluate the performance of 10G bit/s optical single channel transmission systems, which combine with varied kinds of modulation formats, which includes non-return-to-zero (NRZ), return-to-zero (RZ), carrier suppressed return-to-zero (CSRZ), and two kinds of electrical signal process (ESP) techniques which includes linear equalizer (LE) and decision feedback equalizer (DFE). Numerical simulation results show that the combined use of varied modulation formats and equalizer, we can obtain complete different performance improvement.
