摘要:

基于光纤的大传输带宽、微型传能通道、抗电磁干扰等优势,本文设计了一种光载信息能量同传方案.它基于光纤一体化分布式链路,结合微波光子模拟收发前端,同步实现能量远程配送与高频宽带信号的采集传输.首先,设计并测试了光纤传能(Power over Fiber,PoF)链路:高功率激光经多模光纤链路传输2?km后转换为百毫瓦级电能,为远端模块供电或电池充电.在此基础上,设计并测试了基于PoF的光载无线通信(Radio over Fiber,RoF)和电磁干扰检测链路.RoF链路实现了2.4?GHz频段的16QAM-OFDM宽带信号的2?km单模光纤传输;电磁干扰远程采集与监测链路实现了对高铁GSM-R(Global System for Mobile Communications-Railway)无线频段的带内干扰、邻带干扰和带外干扰的检测与识别等.相关方案和系统在易燃易爆、强电磁干扰、强辐射等特殊场景具有重要应用价值.

Abstract:

Based on the distinct advantages of large transmission bandwidth, compact energy transmission channel, and strong electromagnetic interference(EMI) immunity from optical fiber, a hybrid scheme is designed for simultaneous transmission of both information and energy over fiber. Remote energy distribution and high-frequency broadband signal acquisition & transmission are simultaneously implemented, by incorporating a comprehensive fiber distribution link and an analog microwave photonic frontend. Firstly, the power over fiber(PoF) link is designed and experimentally demonstrated. The high-power laser energy is transmitted via a 2 km multi-mode fiber link and then converted into electrical energy of hundreds milliwatts, providing power for the remote module or battery. Moreover, PoF-based radio over fiber(RoF) link and EMI detection link have been also developed and successfully verified. In the experiments, a wideband 16QAM-OFDM signal centered at 2.4 GHz is delivered through the RoF link with a 2 km single-mode fiber. Furthermore, the EMI remote monitoring link is used to perform the detection and identification of in-band, adjacent-band, and out-of-band EMIs for the GSM-R system along the high-speed railways. The proposed scheme and system will find significant applications in specific scenarios, such as inflammable and explosive conditions, strong EMI, and strong radiation.
