There are rich nonlinear wave phenomena in nature, such as optical solitons in fiber optic communication, Alfvén solitons in plasmas, magnetic solitons and spin breathers in Heisenberg ferromagnetic spin chains, Davydov solitons in molecular biology, and so on. The propagation of electromagnetic waves in magnetized plasmas is a significant research topic. Effectively and accurately modeling equations and solving parameters for the electromagnetic-plasma coupling problem in specific scenarios holds great research value and challenges. This is a key exploration into the complex nonlinear interaction mechanisms between electromagnetic waves and plasmas, which is crucial to this research. To enhance the convergence speed of channel equalization in fiber optic communication, a study on the optimization of plasma parameters for nonlinear channel equalization in fiber optic communication was conducted. The analysis of the optical signal transmission model and the primary factors causing channel imbalance revealed that dispersion and disturbances can easily lead to signal distortion in fiber optic communication.
