PERFORMANCE EVALUATION OF RADIO OVER FIBER SYSTEM BY EMPLOYING OPTICAL AMPLIFIERS EDFA AND SOA

Abstract

As per the centralized operations in a radio over fiber (RoF) system, the transmission distance can be increased between the control station and base station. The transferring of the optical signal over large distances results in transmission loss, such as attenuation, fiber tap, fiber splice, etc., which cannot be ignored after a 5 km optical fiber distance, because the transmission losses result in the degradation of signal quality at the receiver end. This creates the need for optical amplifiers to amplify the light signal. The optical amplifiers further enhance the transfer speeds and quantity of transferred data. This paper analyzes the performance of a RoF system by employing optical amplifiers, such as an erbium doped fiber amplifier (EDFA) and a semiconductor optical amplifier (SOA) over different fiber distance. The outcomes and features of an EDFA- and a SOA-based RoF system are also discussed. Finally, the comparative analysis is found by proposed model simulation in OptSIM software. The rapid increment in the undesired nonlinear terms are found over a fiber distance from 5 to 10 km by EDFA- and SOA-based RoF systems, and the obtained results play an important role for maintaining signal quality over fiber transmission distance.
