| 摘 要： | 在WDM光网络系统中，节点如OXC和OADM采用的光器件其非理想性积累构成系统串扰问题。本文提出了WDM光网络系统中串扰问题分析的一般数学模型，根据模型分析比较了WDM光网络中相干串扰和非相干串扰的区别。实验研究了不同非相干串扰代价条件下，对应WDM光网络系统的功率代价。对应1dB功率代价下，实验得出WDM光网络对应非相干串扰代价容限小于－20.8dB的结果。实验结果对于WDM光网络组网规划有一定的参考意义。

| Abstract: | Crosstalks in WDM optical network are originated from the imperfect of optical devices used in the nodes such as OXC and OADM.In this paper,a general analyzing model of crosstalks in WDM optical network is developed.According to the model two different kinds of crosstalks,viz.coherent crosstalk and inconherent crosstalk,are distinguished from each other.The system power penalties are acquired in the experimental study in the conditions of several of inconherent crosstalk penalties,1dB power penalty vs.crosstalk penalty for -20.8dB.The experimental results could be important reference to the WDM optical network scale planning. |
