Characterization of RoF GPON performance for different modulation schemes

Radio over Fibre (RoF) technology provides distribution of broadband signals to base station using an optical access network. This technology reduces the complexity at base station. On the other hand, giga bit passive optical network (GPON) has gained much of the interest in today´s network due to its high data rate (1.2 GHz-2.4 GHz), simplicity, flexibility and low costs. The combination of GPON with RoF technology provides high capacity and high data rate solution. This paper provides characterization of RoF GPON by various simulations performed on OPTSIM software. The statistical analysis of simulation results are based on received signal strength and eye pattern obtained for various modulation schemes at different distances.
