提出并通过数值计算证明，若周期性地改变光纤的三阶色散系数，则可有效地抑制三阶色散对色散位移光纤中孤子效应脉冲压缩的影响
It is proposed and verified by numerical calculations that if the third-order dispersion coefficient of the fiber is periodically changed, the effect of third-order dispersion on the pulse compression of the soliton effect in the dispersion-shifted fiber can be effectively suppressed
