Abstract
Radio over Fibre (RoF) is developing technology in terms of security, reliability and coverage. RoF is efficient is to enhance the capacity and bandwidth for radio signals over long distance. The OFDM with RoF system is used to increase modulation technique and overcomes various limitations such as phase modulation, electrical power attenuation and chromatic dispersion. But the limitation is to use at higher distance. In this paper we design single Rof PON OFDM link at 10Gbps using QAM technique. For increasing distance DCF technique is used and also we also measure the performance of the system at long distance with and without DCF technique. Further the effectiveness of DCF is also checked by increasing channel up to 4 using WDM technique.
