Xu Hengying1, Ma Guangyong1, Bai Chenglin1. Research on AFSA-based multi-channel PMD compensation for WDM systems[J]. 2012,(3):4-6. DOI: 10.13756/j.gtxyj.2012.03.012.
An improved Artificial Fish Swarm Algorithm(AFSA) is applied for the first time to multi-channel Polarization Mode Dispersion(PMD) compensation in Wavelength-Division-Multiplexing(WDM) systems.In this paper
a compensation scheme used in multi-channel PMD compensation is first discussed and then this algorithm is briefly introduced and the detailed steps of its use given.Finally
its effectiveness is verified in a 6×40 Gbit/s RZ-coded PMD compensation system.The simulation results show that the every compensated channel can reach over 0.95 degrees of polarization and the opening of the eye diagram increases after compensation and the algorithm has a good compensation effect.
