摘　　要：本文利用约化摄动重整化方法研究了光纤零色散波长点附近光孤子传输的特征。研究结果表明,光纤零色散波长点附近,光孤子仍然存在并能够稳定地传输,由于光纤损耗和三阶色散效应的影响,光孤子的振幅按指数规律衰减,标准光孤子分裂成孤子和非孤子两部分。Propagation feature of optical soliton near the zero-dispersion wavelength point is researched by using Reductive Perturbation Method(RPM) and Renormalization Method in this paper. The results show that optical soliton still exist and it can propagate stable near the zero-dispersion wavelength point. Because of the influence of fiber losses and the three-order dispersion effects, the amplitude of optical soliton decay as exponential laws and normal optical soliton can be fissioned two parts of soliton and nonsoliton.
