Abstract In anomalous dispersion of monomode optical fiber, an optical soliton is evolved from an optical pulse in the fiber when the nonlinearity is balanced by dispersion. Transmission without distortion, which can greatly improve the capacity and relaying distance of the optical communication system, can be realized by using optical solitons. The mechanism of the generation of optical solitons is expounded. Afew forms of nonlinear transmission equation are obtained by using a simple and clear method. The general complete expression of elementary soliton solution of the nonlinear transmission equation without losses is given, and the design of the soliton transmission system is discussed.
