摘　　要：提出了一个千兆容量的光纤无线系统,该系统通过使用一个集中式光学频率梳(optical frequency comb,OFC),能够应用于高速无线网和密集波分复用(DWDM)接入网之间,每个DWDM用户可以同时获得有线和无线服务,通过该系统传输速率为2.5Gb/s的信号,成功实现了在有线25km单模光纤和6m无线60GHz频段的信号传输,系统传输误码率低于2×10-3。The paper proposes a gigabit capacity fiber-wireless system that enables application between high-speed wireless networks and dense wavelength-division-multiplexing （DWDM） access networks, by em- ploying a centralized optical frequency comb, both the wireline and the wireless services for each DWDM us- er can be simultaneously supported. By transmitting a 2.5Gb/s signal through the proposed system, both the wireline and the wireless signals successfully achieve a bit-error-rate （BER） performance well below 2×10^-3 in the 60GHz band after 25km single-mode fiber plus up to 6m wireless distance.
