Study and performance evaluation of Radio over Fiber using Mach Zehnder Modulator

Abstract

Radio over Fiber (RoF) is attractive technology used for wireless broadband Internet access in which radio signals are modulated on to light and transmitted over optical fiber cable. At the receiving end the optical signal is converted to an electrical signal, amplified and transmitted to the base station. In this paper we have designed a two RF channel optical link over using MZM modulator and the performance of designed link is analyzed at variable optical fiber length based upon variations in BER, Q factor and Eye Diagram analyzer using the Optisystem.
