摘　　要：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 soliton transmission with a bit rate of 1Gbit/s and a distunce of 23km is achieved by employing normal dispersion fiber elimination chirp. The fundamental and high order optical solitons are observed. It is found by the experiment that the spectral width will be changed when the optical pulse of the positive chirp transmitts along normal dispersion fiber.
