Parametric Analysis of Self-Phase Modulation in Single-Tone RoF System

Abstract

Abstract Self-phase modulation (SPM) is one of the major non-linear effect in single-tone radio over fiber system which limits the long-distance transmission as it leads to the broadening of pulse spectrum. In this paper, the mathematical and parametric analysis was carried out to understand the origination and upgradation of SPM and based on results achieved, a rigorous evaluation has been conducted to decrease the impact of SPM. The effect of SPM has been evaluated in terms of optical spectrums, eye diagrams, eye-opening and Q-factor by utilizing four important parameters specifically launched power, fiber effective area, bit rate and fiber attenuation using OptiSystem simulator which reveals insight information for the elimination of non-linear effects.
