串扰对WDM光网络功率管理的影响

Effect of crosstalk on power management in WDM all-optical network

提出了一种新的节点功率管理方案 ,即同时考虑同频串扰和自发辐射噪声的总功率管理 .针对两种节点隔离原则 ,给出了其数学模型 ,并进行了仿真计算 .结果表明同频串扰对WDM光网络的规模和光信号的质量都有着重要的影响 。

A new scheme of node power management in WDM all optical network is proposed, it considers both the intraband crosstalk and ASE noise. The analytical expressions of node isolation principle for different two detection points are given. The simulation calculation shows that the intraband crosstalk has an important limitation on signal quality and network scale while the selection of detection points gives little effect on the signal quality.
