基于一种二阶和三阶色散补偿的光纤级联系统模型,用数值法对啁啾皮秒光脉冲作了传输模拟。结果表明，完全补偿的高阶色散控制系统消除了三阶色散所引起的脉冲边沿部的振荡,减弱了脉冲峰的时间移动；另外，在确定的配置下，给输入脉冲附加一最佳的频率啁啾，可使得色散控制孤子稳定传输。脉冲宽度和啁啾以及光强度都围绕在初始值附近波动，在每个补偿周期末端，基本恢复到初始值；最佳啁啾的选取与二阶色散的配置有关，与三阶色散的配置无关；文中画出了100Gbit/s码率的64位随机高斯光脉冲序列在完全补偿系统中传输10000km后的眼图。由清晰的眼图可知，这种完全补偿系统减弱了脉冲之间的相互作用。

It is shown that by numerical simulation, pre chirped picosecond optical pulse can transmit stably in full dispersion compensation optical fiber links considering not only second, but also third order dispersion compensation using dispersion shift fiber with opposite dispersion signs; it eliminates waveform distortion and peak shift due to the third order dispersion. The optimal pre chirp is relevant to second order dispersion map. During each compensation optical fiber link, pulse width, chirp and peak shift vary around their initial values. It demonstrates that the pre chirp and high order dispersion compensation are two key elements at high bit rate transmission system.
