详细分析了采用频移键控调制方式的光频分复用光纤通信系统中的串扰及其概率密度分布，给出了串扰与频道间距之间的关系，并在确保一定误码率的条件下合理而密集地安排频道间距．
The crosstalk and its probability density distribution in optical frequency-division multiplexing optical fiber communication system using frequency-shift keying modulation are analyzed in detail. The relationship between crosstalk and channel spacing is given. Under the condition of certain bit error rate Arrange channel spacing reasonably and intensively.
