摘要: 对光纤色散及损耗给光纤探针信号前沿和幅度造成的影响进行了理论估算。通过实验对这种影响进行了实际测量。实验中采用四种长度不同的光纤。结果表明，在采用数值孔径为0.37的阶跃石英光纤传输时，光纤色散对光纤探针信号前沿的展宽为5414 ns/km，光纤损耗对光纤探针光信号的影响为4.40.2 dB/km。因此，在光纤需要长距离传输时，有必要采取措施对色散的影响加以控制。

Abstract: Influence of the optical fiber dispersion and loss on the transmission of fiber-optic pin signals has been estimated in theory. The influence has been measured by experiment. Four optic fibers of different lengths have been used in this experiment. The results indicate that when a step index quartz optical fiber with NA=0.37 is used ，the influence of the optic fiber dispersion on rise time of signals of fiber-optic pin is 5414 ns/km，the loss of optic signals is 4.40.2 dB/km. So when a long fiber is used，a method that can reduce the optic fiber dispersion is necessary.
