Abstract
In an optical communication system it is necessary to place the solitons close to one another to increase the information carrying capacity of the fiber. The theory of soliton–soliton interaction in a fiber optic communication system, through a single channel, is studied in this paper. In presence of the perturbation terms, the two soliton interaction of the Nonlinear Schrödinger's Equation is investigated. It is analytically proved and numerically supported that the perturbation terms lead to the suppression of the interaction of solitons through an optical fiber.
