In this paper, the authors presented a system design that integrates Coherent-Optical-Orthogonal-Frequency-Division Multiplexing (CO-OFDM) with Wavelength-Division Multiplexing - Radio over Fiber (WDM-RoF) together with dispersion compensation technique to offer a data rate of 48Gbps over more than 80km Single Mode Fiber (SMF) by multiplexing four 12Gbps OFDM channels. In the designed system model Fiber Bragg Grating (FBG) was introduced as the filter to encounter mainly the effect of dispersion. Furthermore, they evaluated the performance of CO-OFDM/WDM-RoF design with and without FBG by measuring the Q-factor, Bit Error Rate (BER) and constellation diagram.
