| 摘 要： | 当光纤通信系统单信道速率升级到40 Gbit/s以上时,偏振模色散(PMD)已经成为严重影响系统性能的主要因素.PMD是由于光纤结构的不完美性以及外界应力作用而产生的,是一个服从Maxwell分布的随机量.文中对现有的PMD抑制技术进行了分析评价,并针对波分复用系统中PMD的补偿提出了可行性的方案.

| Abstract: | When bitrate of optical fiber communication system comes to 40Gbit/s,polarization mode dispersion(PMD)will be a dominant factor of degrading system performance.PMD in fiber is formed due to the non-ideal structure and the action of external stress on optical fiber and is a stochastic variable.Some PMD mitigation methods are described and compared.A feasible PMD compensation method in wavelength-division-multiplexing optical fiber communication system is proposed. |
