利用正常色散光纤消啁啾成功地进行了1Gbit／s、23公里的光孤子传输，观察到了一阶和高阶孤子传输现象。通过实验发现：采用适当长度的正常色散光纤消负啁啾，不仅能够压窄负啁啾的脉宽而且能够压窄频谱。
The transmission of optical solitons at 1 Gbit / s and 23 km was succeeded by eliminating chirp with normal dispersion fiber, and the phenomena of first-order and higher-order soliton transmission were observed. Experiments show that using a normal dispersion fiber of proper length to eliminate the chirp can not only narrow the pulse width of the negative chirp but also narrow the spectrum.
