Abstract

In this paper, we present the si mulation results on the investigation of the impacts of PMD on the PolSK optical transmission system. The model used for this study is a dual-channel, direct-detection PolSK optical transmission system with improved receiver architecture. The quality Q factor of system is used as a parameter to evaluate quantitatively PMD effects on the performances of this dual-channel PolSK system. The simulation results show that the PMD severely impairs the transmission performances of the PoLSK system and resultantly limits the bit rate. The results also show that with PMD compensation, the performances of the PolSK system can be effectively improved and the bit rate increases greatly from 6 Gb/s to 22 Gb/s.
