波分复用环网功率管理方案

Power Management Design in WDM Ring Network

提出一种新颖的功率管理方案 ,用于波分复用全光环网中 .它以节点孤立原则为基础 ,采用预均衡技术对经掺铒光纤放大器 ( EDFA)放大后的所有光信道功率均衡 ,简化了网络监控方案 ,增强了网络监控功能 .把该功率管理方案应用到 SHAONET全光通信环网试验平台中 .计算机仿真结果与实验结果十分吻合 ,证明提出的环网功率管理方案是可行。

A novel power management project for alloptical WDM ring network was introduced. Based on the node isolation principle, it adopts preemphasis technique to equilibrate the EDFA output power of all signal channels. It has the benefits to simplify network control and administration design and to enhance the relevant function simultaneously. This power project was applied to SHAONET. The simulative and experimental results agree well with each other and confirm that this project is feasible and effective for WDM ring network.
