摘要
在研究局部偏振模色散矢量与整体偏振模色散矢量关系的基础上 ,从理论上得到完全补偿偏振模色散的关系 ,结论是至少利用两段保偏光纤才能完全补偿。提出了基于偏振模色散矢量的偏振模色散补偿方案和调节控制的算法原理及改进的方向。这些结果对正确进行偏振模色散补偿是很有帮助的。
Based on discussing the relationship between vectors of local and whole polarization mode dispersion (PMD), a formula which lead to completely compensate PMD is preseted. The conclusion is the to completely compensate PMD at least two segment polarization maintenance fiber (PMF) must be used. The compensation element schemes and adjustment algorithm program are suggested. Compared with traditional method, analyses the PMD vector of fiber to get adjustment parameter and leads to compensate completely. The conclusions are important to PMD compensation correctly.
