    The pulse compression is affected by group-velocity dispersion parameter (GVD) and nonlinear parameter of the anomalous-dispersion compensative fiber in self-similar pulse compression technique. This effect was studied with numerical calculation based on nonlinear Schr?dinger (NLS) equation. The results show that compensative fiber’s GVD parameters affect compression factor and peak power of compressed pulse periodically. Pulse energy concentrates, disperses, and then concentrates in every period. As the magnitude of GVD parameter increases, period interval becomes longer and more energy diverts. Every time when energy concentrates, the pulse width approaches the compression limit. Optimal fiber length is a decreasing function of the magnitude of GVD parameter, but it has nothing to do with nonlinear parameter. On the other hand, the increase of nonlinear parameter reduces compression factor, which is bad for pulse compression. By optimizing the parameters of the compensative fiber, pulse width can attain its limit and high quality pulse is obtained.
