| 摘 要： | 偏振模色散(PMD)在40Gb/s或更高速率的光纤通信系统中已成为限制系统性能的主要因素.为使PMD补偿经济、控制方便,具有一定的工程实用价值,提出了一套采用两级固定时延补偿结构的PMD部分补偿方案,设计并制作了PMD补偿器,在实际传榆线路中进行了测试.测试结果与光通信系统设计软件Optiwave Optisystem模拟补偿效果进行了对比,优化了补偿器的各项参数.在对实际敷设的四组长约60 km的光纤链路的补偿试验中所得结果与计算结果符合较好,实现了15～20%的补偿量.

| Abstract: | Polarization Mode Dispersion (PMD) has become a dominate limiting factor in 40 Gb/s and higher speed fiber-optics communication systems.In order to make the PMD compensation scheme cost-effective and easy to install in practical communication fiber paths,a PMD partial compensation scheme based on two-stage fixed delay structure was designed,fabricated and tested in practical underground fiber links.The performance of this scheme was examined by using optical communication system simulation software Optisystem 3.0,and parameters of the compensator were optimized.Compensation experiment for four 60 km-long installed fiber cable links was in a good agreement with the simulated result,with a 15～20% of PMD compensation achieved. |
