Wireless networks based on radio over fiber (ROF) technologies have been proposed as a promising solution to meet the future demand on broadband, interactive and multimedia services over wireless media. However, millimeter-wave band signals suffer from the dispersion problem in fiber, and the structure of base station is complex. A full-duplex 60 GHz band ROF system employing a 60 GHz electroabsorption transceiver (EAT) together with a dual-lightwave technique is reported. By realizing single- and dual-wavelength modulation in downlink and uplink respectively, a base station with detection, modulation and frequency up/down-conversion functions which acts as a electroabsorption transceiver/mixer is obtained. Simultaneously, its chromatic dispersion is small and base station structure is simple.
