摘　　要：研究了双光纤波分复用互联网在不同网络容量使用率时的阻塞率,主要对单光纤网络使用波长变换器和双纤网络在波长数不同时对网络阻塞率的改善情况做了仿真比较,结果表明仅仅在低阻塞率时波长变换器给网络所带来的增益非常有限,双纤网络可以达到其效果。The blocking probability under different utilization of network capacity of dual-fiber Wavelength Division Multiplexing (WDM) optical network is studied. A simulation to the improvement of blocking probability is carried out for single fiber network and dual-fiber network, the former with a wavelength converter. The simulation shows that the utilization gain in low blocking probability is little better due to the converter, while the dual-fiber network can attain the same effect.
