摘要
介绍了采用EDFA系统与采用混合RFA/EDFA系统的两种WDM网络,在放大器正常放大、遭受大功率信号攻击、遭受大功率噪声攻击三种环境下进行研究,通过理论分析和仿真试验得出,在系统QoS性能方面,采用混合RFA/EDFA的系统优于只采用EDFA的系统。
This paper introduces two kinds of WDM networks-composed of EDFA and of hybrid RFA/EDFA. Three working circumstances of amplifiers-normal amplification, attacked by high power signal, and attacked by high power noises-have been researched. By theoretical analysis and simulation experiment, a conclusion has been reached： QoS performance of hybrid RFA/EDFA system is better than that of EDFA system.
