14 December 2011PMD impacts on dual-channel PolSK optical transmission system
In this paper, we present the simulation 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.
