Parallel transmission of solitons without interactions

Abstract

Soliton interactions affect the pulse quality and capacity of communication systems. In this paper, parallel transmission of solitons without interactions are investigated to improve the pulse quality and capacity. Analytic two-soliton solutions for the variable coefficient nonlinear Schrödinger equation are obtained.The exponential profile of optical fibers is suggested to derive the parallel transmission of solitons, and influences of corresponding parameters are analyzed.

Keywords:
