The Influence of the Fourth-Order Dispersion Coefficient for the Information Transmission in Fiber

For the problem caused by optical fiber dispersion in optical fiber communication the new method was proposed. The new method was from Maxwell equation and based on two aspects. One was the approximation of the quasi monochrome and slow change envelope. Another one was the assumption of the nonlinear polarization. The higher-order nonlinear Schrödinger equation of the envelope wave for describing the fiber had been established. The analytical solution for the fourth-order dispersion coefficient in the nonlinear Schrödinger equation had been obtained by the strict formula deduction. The results were shown that the total energy was as exponential deceasing with the transmission distance along the transmission direction of the optical fiber when the fourth-order dispersion coefficient was considered in nonlinear Schrödinger equation.
