This equation can be used to describe the nonlinear effects of the system caused by loss, dispersion, and other factors during optical signal transmission in optical fibers. The soliton solutions and periodic solutions of the equation are obtained, and the two-dimensional and three-dimensional evolution behaviors of the system are presented.展开更多
