摘要
将光纤通信技术应用于无线通信网络而构成的光纤无线通信系统,已成为当前学术界研究的热点。文章首先概述了光纤无线通信系统的基本结构和特点,然后详细介绍了光纤无线通信系统中的一些关键技术。通过对光毫米波信号的产生方法和无源基站设计的研究,介绍了一种新的全双工ROF系统,并进一步分析了色散对光毫米波ROF通信的影响。最后展望了光纤无线通信技术的应用前景。
Radio over Fiber （ROF） system, which involves the application of fiber communication technology in radio communication network, has become the research focus at present. This article first outlines the basic structure and characteristic of ROF system, and then tells of in detail some key technologies in ROF. Through the study of optical millimeter-wave generation and passive base-station design, a novel full-duplex ROF system is proposed, and the effect of fiber dispersion on millimeter wave ROF is analyzed. Finally, the application prospects of ROF technology are given.
