摘　　要：分析了在微波光子链路系统中,色度色散与偏振模色散对微波光子信号的作用。通过对传输系统模型的理论推导可以发现,对于双边带调制信号,色度色散将引起信号功率的衰落,而单边带调制方式可以避免这一情况;而如果存在偏振模色散,即使是单边带信号也会出现信号功率衰落现象,并随传输距离表现出周期性。The research on the influence of chromatic dispersion and polarization mode dispersion in microwave photonic link is presented. According to analysis and derivatin of the transmission model, it can be found that the chromatic dispersion is able to cause the power fade on double side -band modulated microwave signal. However, it does not happen for single side - band modulated signal. If the polarization mode dispersion effect exists exists, even single side - band modulated signal will suffer from power fade, and shows periodic behavior with transmission distance.
