Abstract
Radio over fiber (RoF) is an amalgamation of both optical and wireless technologies offering the benefits of high information rate and increased mobility. In this paper, a full-duplex RoF passive optical network (PON) is proposed based on wavelength remodulation using fiber Bragg grating (FBG). Simulation of the proposed system demonstrates 1Gbps uplink and 1Gbps downlink signals sharing the same continuous wave (CW) laser source located at the remote central station (CS). The performance of the system is investigated in terms of bit error rate (BER), optical signal-to-noise ratio (OSNR), received optical power and eye diagrams of the transmitted signals. From the result, it is observed that the proposed sensor gives us an acceptable result at 100 Km with BER 10−9, output power 9 dB m and OSNR 36 dB. The results show that the network performance is improved by decreasing the overall dispersion of the fiber link using FBG and dispersion compensating fiber (DCF). The system exhibits smooth execution up to a transmission distance of 100 km and henceforth, is capable of supporting long haul transmissions.
