Propagation of spectra affected by third - order dispersion in dispersion - decreasing fiber near zero dispersion wavelengths was studied by means of numerical simulation 摘要为探讨三阶色散对脉冲传播的意义，用数值模拟的方法讨论了在色散缓变光纤中零色散波长附近三阶色散对脉冲频谱演变的影响。

It is more suitable for the broader sc spectrum generation when the dispersion curve of the fiber is flatter and distance between the two zero - dispersion wavelengths of the fiber is farther from each other 光纤的色散曲线越平坦，色散曲线的两个零色散波长相距就越远，也越有利于超连续谱的展宽。
