| 摘 要： | 在高速光纤通信系统中,偏振模色散(PMD)已被认为是限制光纤通信系统性能的一个主要因素,而脉冲的均方根展宽是表征信号传输性能的一个重要的物理量.研究了偏振模色散对脉冲展宽的影响,推导出含有一阶偏振模色散补偿的光纤链路中偏振模色散矢量的自相关函数的分析表达式.在此表达式的基础上,推出了以高斯脉冲为例的一阶偏振模色散补偿系统中的均方根脉宽解析表达式.

| Abstract: | At high bit rates fiber transmission systems,polarization mode dispersion(PMD)is considered as the ultimate limiting factor for transmission of information.The pulse root mean square broadening is a main physical variable to judge signal transmission performance.We derive the broadening effects induced by the PMD,and give the exact analytical expressions for the expected pulse broadening in a fiber-optic transmission system suffering from first- order polarization mode dispersion(PMD).Furthermore,we use the result to calculate the Gaussian pulse. |
