“…The second-order free dynamic range is 52dB Hz and the third-order free dynamic range , also called the spurious-free dynamic range (SFDR), is 65 dB Hz . This is comparable with the values reported in [38] (for an amplified 120 km optical link operating at 5 GHz, with an EAM source), but less than the 106 dB Hz obtained using a DBR source without RF preamplification [39], or the 115 dB Hz obtained using a DFB with RF preamplification [40]. The 1 dB compression point of our system was at 4 dBm input power, which is suitable for short-range picocellular applications requiring low launch RF power levels: other authors [20] have previously reported 7 dBm output power level corresponding to a 1 dB compression point, but with a more complex architecture.…”

Abstract-We present an all-optical adaptive-antenna radio over fiber transport system that uses proven, commercially-available components to effectively deliver standard-compliant optical signaling to adaptive multiantenna arrays for current and emerging radio technology implementations. The system is based on a directly-modulated reflective semiconductor amplifier (R-SOA) and exploits the interplay between transmission-line dispersion and tunable optical filtering to achieve Index Terms-Beamforming, mobile communications, optical access networks, radio over fiber (RoF) networks, WiMAX.
