研究了有限范围波长转换在不同路由和波长分配算法下的阻塞性能增益。研究了交叉增益调制（XGM）和四波混频（FWM）有限范围波长转换器。通过在两种网络中的仿真，比较了它们的性能增益，结果表明，交替RWA算法对性能增益影响很大，交替路径数影响FWM波长转换范围，其性能接近理想波长转换。
The blocking performance gain of limited-range wavelength conversion under different RWA (routing and wavelength assignment) algorithms is studied. XGM (cross-gain modulation) and FWM (four wave mixing) limited-range wavelength converters are investigated. By simulation in two networks, their performance gains are compared; the results show that the alternate RWA algorithm greatly impacts on the performance gain, and the number of alternate paths influences the FWM wavelength conversion range for which its performance is close to the ideal wavelength conversion.
