摘　　要：随着5G通信时代的来临,大容量、高频段和多业务接入的移动通信网络建设面临诸多挑战。在5G网络中,由于5G信号的高频段特征,基站覆盖范围大大减小,需要布设的基站数量急剧增加,为了保证覆盖能力,并降低总体的成本和功耗,基站正在向小型化、密集化、无源化方向发展。而光纤信能共传技术为实现新一代分布式微基站提供了解决方案,此技术通过光纤将射频信号和能量光传输至基站,为基站供能的同时,利用天线完成无线宽带信号的发射。介绍了光纤信能共传技术近年来的研究进展,并通过分析典型方案的特点,阐述了光纤信能共传技术的发展趋势。With the advent of the 5 th generation(5G)wireless systems,the development of mobile communication networks with large capacity,high frequency,and multi-service access is confronted with enormous challenges.In the 5 G network,since the high-frequency signals are adopted,the coverage of a base station is greatly reduced and the number of base stations to be deployed is dramatically increased.Thus,the base stations tend to be miniaturized,densified,and passive for a large total coverage range together with lower overall costs and power consumption.The power-over-fiber(PoF)technique applied to radio-over-fiber(RoF)systems provides a solution to a new generation of distributed micro base stations.This technique,by transmitting the radio-frequency signals and power light to the base stations via optical fibers,achieves the power supply for the base stations and the emission of the wireless broadband signals with antennas.In this paper,we introduced the recent research progress of the PoF for RoF systems and analyzed its development trend by summarizing the features of typical schemes.
