摘　　要：采用守恒量扰动法定量计算了色散管理光孤子受ASE噪声的影响而产生的中心频率漂移。结果表明,与普通光孤子相比,色散管理光孤子对ASE噪声有较好的抑制作用。In the paper, the center frequency excursion influenced amplifier spontaneous-emission noise in the dispersion-managed soliton communication systems is calculated by using the conservation quantity distributing method. The result shows that the dispersion-managed optical soliton has better control effect than general optical soliton on amplifier spontaneous-emission noise.
