Application of nonlinear Schrödinger equation in high speed optical soliton communication systems

In order to analyze the property of optical soliton communication system, split-step Fourier method was used to calculate the nonlinear Schrödinger equations.The simulation results showed that the transmission characteristics of pulse became deteriorated as the parameters of polarization mode dispersion increased.At last, the interaction between solitions was analyzed and the measure for improving the optical soliton communication system was proposed.
