摘　　要：研究了Ｆ－Ｐ型解复用器在密集波分复用系统中引入的信道间串扰对系统的影响。理论上分别建立了Ｆ－Ｐ的信道串扰模型和接收机的误码率模型，并与实验结果进行了比较。在此基础上讨论了密集波分复用系统中Ｆ－Ｐ型解复用器带宽的参数优化。Crosstalk due to the F P demultiplexer in HD WDM systems is investigated. The models about crosstalk due to LD Linewidth and F P Filter bandwidth and the BER of the receiver are presented and verified by experiments. Based on the models, optimized bandwidth of the F P demultiplexer is discussed.
