Abstract
In this paper, a generalized nonlinear Schrödinger equation with variable dispersion and nonlinear coefficients, which can be used to describe the pulse transmission in inhomogeneous optical fibers, is investigated analytically. By virtue of the Hirota method, analytic multiple soliton solutions are obtained. Interactions between solitonics are presented through choosing specific nonlinearity functions, and interaction properties of them are analyzed. Results obtained may potentially be useful in the area of optical communications.
