Abstract
We proposed a new bidirectional gigabit wavelength division multiplexed/radio on fiber (WDM-RoF) system which shares the same wavelength. A central station for downlink transmits a 3GHz wireless signal which is modulated 1.25Gbps by use of a mach-zehnder modulator. A base station for uplink a transmits 1.25Gbps down-converted wireless signal by using a reflective semiconductor optical amplifier. We achieved a BER<10-9 of the downlink at -18.3dBm and of the uplink at -22dBm after 20km transmission.
