In this study, the eight order nonlinear Schrödinger equation modeling the pulse propagation in optical fiber is discussed. Optical fibers is used for long-distance and high-performance data networking which making it the logical choice for data transmission. For this reason, it becomes important to examine these type equations. Three different useful and effective methods have been used to obtain optical soliton solutions of this equation. In addition, it is tried to give more information about the dynamic performance of the model with the help of three-dimensional graphics. Finally, the stability property of the obtained analytical solution was investigated based on Hamiltonian systems.

在这项研究中，讨论了建模光纤中脉冲传播的八阶非线性Schrödinger方程。光纤用于长距离和高性能数据联网，这使其成为数据传输的合理选择。因此，检查这些类型方程变得很重要。已经使用三种不同的有用和有效方法来获得该方程式的光学孤子解。此外，尝试借助三维图形提供有关模型动态性能的更多信息。最后，基于汉密尔顿系统对所得解析解的稳定性进行了研究。
