报导了一个40Gbit/sOTDM系统中二阶偏振模色散(PMD)自适应补偿系统,此实验系统基于偏振度的反馈控制方法实现了二阶偏振模色散自动补偿 在中心波长1560. 5nm处,补偿后的DGD和二阶PMD效应改善明显 采用粒子群优化算法作为偏振模色散自适应补偿的搜索算法,补偿时间30ms左右
Reported a second-order polarization mode dispersion (PMD) adaptive compensation system in a 40 Gbit / s OTDM system. The experimental system based on the polarization feedback control method to achieve the second-order polarization mode dispersion automatic compensation at the center wavelength of 1560. 5nm, after compensation The DGD and second-order PMD effects are significantly improved using Particle Swarm Optimization (PSO) as the search algorithm for PMD adaptive compensation with a compensation time of about 30 ms
