To Overcome the Effects of Self-Phase Modulation in Single-Tone RoF System by Employing SSP Compensation Technique

Abstract

Self-Phase Modulation affects the performance of Radio over Fiber (RoF) system by inducing spectral broadening of the transmitted pulse and thereby produces dispersion. This paper analyses the effects of SPM on optical pulse propagating through the fiber and proposed a SSP (symmetrical-symmetrical-post) compensation technique to overcome the effects of SPM in single-tone RoF system. The simulation results reveal that the pulse broadening due to SPM is reduced by utilizing SSP compensation technique in the transmission channel as it provides a 2 dB increase in OSNR as compared to the conventional compensation technique. The proposed technique provides an optimum result at a bit rate of 40 Gbps and launched power of 10 mW over a transmission distance of 400 km for mitigating SPM effects.
