For the problems of the attenuation and the dispersion in long distance fiber communication of optical information, the optical soliton communication is an effective method. The flexible soliton solution has been obtained from the solution of the nonlinear Schrdinger equation with the group-velocity dispersion, linear potential, three-order nonlinearity term, and the gain/loss term. A trial solution that was a travelling wave solution with complex amplitude was used and it was replaced into the nonlinear Schrdinger equation. The three new variables were introduced after the nonlinear Schrdinger equation was separated into imaginary part and real part. Finally the square of wave-function of soliton solution and the consequence figures was got with Matlab. The results show that the soliton solution is sensible for various parameters. The appropriate soliton was obtained by reasonable parameters choice and it made the foundation for the soliton communication in the optical fiber.
