提出了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EDFA放大后的所有光信道功率均衡。这样不但简化了网络监控方案 ,同时增强了网络监控功能。最后 ,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 ,证明该环网功率管理方案是可行且有效的。
A novel power management scheme is proposed for WDM networks. It is based on the principle of node isolation, and adopts the pre-equalization technique to equalize the power of all the optical channels amplified by the EDFA. This not only simplifies the network monitoring program, while enhancing network monitoring capabilities. Finally, this power management scheme is applied to SHAONET all-optical communication ring network test platform. Computer simulation results are in good agreement with the experimental results, which prove that the ring network power management scheme is feasible and effective.
