| Abstract: | 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. |
