High Speed 4 × 2.5 Gbps-5 GHz AMI-WDM-RoF Transmission System for WLANs

Abstract

Abstract Radio-over-fiber (RoF) is revolutionary technique to transmit radio signals over optical fiber. It can be also suitable to distribute wireless local area networks (WLANs) due to its low-cost implementation. WLANs generally operate on 5 GHz radio signals. Thus in this work, four high speed radio channels, each carrying 2.5 Gbps data and 5 GHz radio signal, are transmitted by incorporating alternate mark inversion (AMI) scheme and wavelength division multiplexing (WDM) scheme over optical fiber having span of 50 km. The performance of proposed AMI-WDM-RoF transmission system is reported in terms of Q-factor, bit error rate, signal-to-noise ratio, total received power and eye diagrams.
