对负啁啾脉冲在正常色散光纤中传输特性进行了数值分析和实验研究，数值分析结果与实验结果基本一致。数值分析和实验证明正常色散光纤不仅能压窄负啁啾的脉宽而且能压窄频谱，采用正常色散光纤消啁啾后用色散位移光纤作为传输媒质成功地进行了一阶和高阶孤子传输。
The transmission characteristics of negative chirped pulse in normal dispersion optical fiber are numerically analyzed and experimentally studied. The numerical results are in good agreement with the experimental ones. Numerical analysis and experimental results show that the normal dispersion fiber can not only narrow the pulse width of the negative chirp but also narrow the spectrum. The first order and the high order soliton transmission are successfully performed using the dispersion-shifted fiber as the transmission medium after eliminating the chirp by normal dispersion fiber .
