摘　　要：介绍了基于EDFA+NDF实现波长转换的理论模型,借助OptiSystem软件重点研究了影响波长转换效率的几个特性参数,即EDFA的泵浦增益值的大小、光纤的衰减系数、非线性色散光纤的长度和光纤的有效面积,最后给出一组合理的参数使波长转换器有15.149dB的转换效率,这对于优化基于ED-FA+NDF的全光波长转换器有重要参考价值。The theory model of all optical wavelength conversion is introduced based on the Erbium-doped fiber amplifier and nonlinear dispersion fiber, and the characteristics are focus analyzed in the Optisystem software such as EDFA＇s pumped gain, fiber attenuation coefficient, the length of nonlinear dispersion fiber and the fiber＇s effective area. Finally a set of reasonable parameters is given and the AOWC has 15.149dB conversion efficiency. These results are useful to the optimal design of the wavelength converter based on the EDFA and NDF.
