本文讨论了当光源受高斯脉冲调制时，考虑波导三阶色散项时，脉冲在单模光纤中的扩展。解析地得到脉冲形状的一般表达式，并且当三阶色散项较小时，使用渐近近似。当三阶色散项变大时，脉冲宽度不再与波导长度成正比。
Pulse spreading in a single-mode optical fiber is discussed taking into account the third-order dispersion term of the waveguide when the light source is modulated by a Gaussian pulse. A general expression for the pulse shape is analytically obtained, and an asymptotic approximation is used when the third-order dispersion term is small. It is also shown that the pulse width is no longer proportional to the guide length when the third-order dispersion term becomes large.
