Interactions between Crosstalk in Wavelength Division Multiplexing and Graded index Optical Fiber Parameters

Abstract

In this paper, an interaction between multimode graded-index optical fiber parameters with crosstalk and spatial shift in Wavelength Division Multiplexing (WDM) technique is presented. Pulse spreading caused by linear effects in optical fiber due to dispersion is considered in this proposed system. Results show how channel spacing, fiber core radius and spatial shift affect on the crosstalk. Furthermore, the significance of fiber length, chirp parameter and refractive index profile parameter on crosstalk is presented and analyzed in detail.
