| 摘 要： | 在波分复用(WDM)系统中不同信道之间的串扰将恶化每路信号的消光比,而多波长光交叉连接网络中还会出现带内串扰的情况,它所产生的拍频噪声对系统的影响远大于带间串扰。从不同的角度分析了这两种串扰,理论分析的结果与实验现象吻合良好。

| Abstract: | The interband crosstalk in the WDM system will degrade the system BER by penalizing the extinction ratio in each channel. But in multi- wavelength optical cross-connect networks, there is another kind of crosstalk, intraband crosstalk, in addition to the interband crosstalk. The intraband crosstalk will result in beat-noise which can be detected by the receiver and has more severe impact on the system BER than interband crosstalk. In this paper, we analyze two kinds of crosstalks, and show that our calculated results coincide with the results from experiment very well. |
