摘　　要：基于多波长泵浦与级联光纤相结合的方法,文章使用遗传算法对泵浦波长、功率及两段光纤的长度进行优化,采用数值解法对100信道的波分复用系统进行仿真获得了约0.0695 dB的增益平坦度,增益值为13.15 dB。同时对泵浦光功率和信号光功率随光纤长度的变化进行了分析。On the basis of combining multi-wavelength pumps and cascaded optical fibers, the paper optimizes the pump wavelength, power and the length of two sections of fibers by using the genetic algorithm and simulates the 100-channel WDM system by using the numerical method and obtains about 0. 069 5 dB gain flatness with a gain value of 13.15 dB. Furthermore, it analyzes the variations of the optical pump power and signal power with the fiber length.
