摘　　要：对不同波长的光脉冲在由正负色散光纤组成的光纤链中的传输特性进行了数值分析和实验研究。实验结果和数值分析表明，在相同的初始条件下，短距离传输时，采用平均色散为正常色散的光纤传输要优于孤子传输方式，长距离传输时，采用孤子传输要优于脉冲在平均色散为正常色散的非线性光纤中传输。在正负色散位移的光纤链中的孤子传输，有一最佳波长。A fiber ring laser with tuable wavelength and repetitive frequency is successfully made.The optical pulse with different wavelength transmitting in the fiber chain composed of normal and abnormal dispersion fiber waw researched experimentally and numerically.The results show that with the same initial condition,nonlinear optical pulse transmission in average normal fiber is superior to soliton transmission in short distance.However,soliton transmission is superior to nonlinear optical pulse in long distance.There exists an optimum wavelength with the optical fiber chain composed of normal and abnormal dispersion fibers in long distance transmission.
