摘　　要：在不考虑光纤中的非线性效应时,通过对高斯和超高斯脉冲光源啁啾的色散理论模型和传输测试分析,得到色散限制关系式,对于色散系数D沿光纤长度z变化的情况,只要光发射机与光接收机间光纤的累积色散∫Ddz小于关系式中所限定的数值,啁啾对脉冲波形的影响就可获得明显减弱,为此给出各种色散补偿方法。Regardless of nonlinear effect of optic-fiber,the paper examines the dispersion model and transmission test with the chirping of Gauss and super Gauss pulse light source and finds a function of restriction accordingly.It finds that when dispersion coefficient D varies along with an optic-fiber of length z,as long as the accumulated dispersion between light transmitter and light receiver ∫Ddz is within the limit number of the function,the influence of the chirp upon the pulse form can be expected to abate obviously.The paper presents various method of compensation for dispersion.
