摘　　要：基于光孤子传输所遵从的非线性薛定谔方程(NLSE),参照相关的实验数据,借助MATLAB的计算和绘图功能对光孤子脉冲在普通单模石英光纤中得以保形传输的条件进行了数值模拟,得到了在给定光纤参数下孤子脉冲的截止脉宽。Based on the nonlinear Schrdinger（NLS） equation and using the MATLIB,numerical analysis was made to simulate the transmission of optical soliton pulse in mono-mode quartz fiber.The condition for conformal transission was analyzed.Model was set up with which one can calcalate the minimnm pulse width fo conformal transition.The factors that decide the minimnm pulsewith include the chirp modulation coefficient,the parameters of the fiber,etc.The result and conclusion can be referenced when dealing with the field of high speed soliton communication.
