基于光纤无线通信(ROF)的无线网络被认为是提供高带宽、交互式和多媒体无线通信服务很有前景的实现方式,但目前毫米波频段的光纤无线通信系统都存在色散严重或基站结构复杂等问题。设计完成了一个全双工60 GHz的光纤无线通信系统,利用双光源技术和60 GHz的电吸收收发器(EAT)分别在下行和上行链路实现单波长和双波长调制,完成基站的探测、调制、射频上变频和下变频四种功能,在基站中实现了电吸收收发/混频器(EATX),从而避免了制作电吸收收发/混频器件,同时也解决了光纤无线通信系统中常见的色散和基站结构复杂等问题。
Wireless networks based on optical fiber wireless communication (ROF) are considered as promising promising ways to provide high-bandwidth, interactive and multimedia wireless communication services. However, the existing optical fiber wireless communication systems in the millimeter-wave band have serious dispersion or complicated base station structures problem. The design completes a full duplex 60 GHz optical fiber wireless communication system. The dual-light source technology and the 60 GHz EAP transceiver are used to realize single-wavelength and dual-wavelength modulation on the downlink and the uplink, respectively, to complete the base station detection. Modulation, radio frequency upconversion and downconversion four functions, in the base station to achieve the electroabsorption transceiver / mixer (EATX), thus avoiding the production of electro-absorption transceiver / mixing devices, but also to solve the optical fiber communication system is common Dispersion and base station structure and other issues.
