摘要：Wireless coverage of the end-user domain; be it outdoors or indoors, is poised to become an essential part of broadband communication networks. In order to offer integrated broadband services (combining voice, data, video, multimedia services, and new value added services), systems will need to offer higher data transmission capacities. The need for increased capacity per unit area leads to higher operating frequencies, smaller radio cells and large number of base stations (BSs), therefore cost-effective BS development is a key success to the market. For this radio over fiber (RoF) technology has been proposed since it provides functionally simple BSs that are connected to a central station (CS) via an optical fiber. A full-duplex data and video signal transmission over single-mode fiber (SMF) based on wavelength-division-multiplexing (WDM) and an optical add-drop multiplexing (OADM) technique is proposed and simulated. Four data signals of 1.25 Gb/s /9.1-9.4GHz are transmitted over long-haul single-mode fiber for downlink transmission. For uplink transmission, four data signals, each from a BS, of 1.25 Gb/s/9.6-9.9GHz is used. Good bit error rate (BER) performances were achieved for both down-link and up-link transmissions in our full-duplex RoF transport system
