The effect on pulse compression in dispersion-managed fibers is studied.The higher pulse compression ratios are obtained in both zero total dispersion fibers and nonzero total dispersion fibers.The optimum fiber length of the latter is about half of the former.When higher-order dispersion and higher-nonlinear effects are considered

the quality of compressed pulse becomes worse.The destructive effect in the dispersion-managed fiber of nonzero total dispersion is more serious.
