Abstract
Abstract An innovative cost-effective fourth-generation bidirectional wireless hybrid transport system, employing optical add-drop multiplexing technique, power doubler amplifier and data comparator, is proposed and experimentally demonstrated. The proposed system can transmits, downlink 80 community antenna television (CATV) channels, two different wireless-over-fiber (WoF) data signals (1.5-Gbps/2.4-GHz, 2.5-Gbps/3.5-GHz) at two different base stations over 40 km and 80 km single-mode fiber (SMF), respectively, and an uplink 5-Gbps baseband (BB) signal at central station over 40 km SMF, using a single optical carrier. The good carrier-to-noise ratio, composite-second order and composite-triple bit are achieved for CATV channels, and small BER and open eye-diagrams are achieved for WoF and BB signals.
