摘要：
We propose the configuration of signal multiplexing with four polarization states and investigate its transmission performance over single-mode fiber links. Using coherent detection and digital signal processing, a demodulation scheme for four-polarization-multiplexed (4PM) system is presented. We discuss the impact of crosstalk from polarization mode dispersion and polarization beam splitter misalignment on the proposed 4PM system. Furthermore, the transmission distance could be doubled to similar to 50 km by employing feedback decision equalizers.
