Abstract

We propose a bidirectional Radio-over-Fiber (RoF) system with multi-band signals generation technique using a single phase modulator (PM). At central office (CO), a PM is used to modulate optical carrier and generated signal is transmitted through a single mode fiber (SMF). At base station (BS), three different signals are generated from the received optical signal, including 60 GHz millimeter wave (MMW) signal, 24 GHz microwave (MW) signal and baseband (BB) signal. Bidirectional transmission is achieved by reusing downlink optical carrier for uplink data transmission, which eliminates the need of optical source at BS. An error-free transmission of 3 Gb/s data through 60 km SMF, is achieved for all the signals. Electrical and optical domain representations are shown at different points and the variations in min. log of BER against received optical power (ROP) are plotted on graph
