Modeling of non-linear crosstalk in optical fiber

Abstract

This article is intended to provide a new method for modeling of nonlinear crosstalk in optical communication system. It is necessary for the optical link designer to understand the transmission impairment due to fiber nonlinearity for efficient link design. In the present paper a new mathematical model is derived for SRS and XPM crosstalk, which has less variable and compact form. The expression for crosstalk derived in the present work shall be useful to find the total crosstalk and in predicting its countermeasure techniques in optical link design.
