摘　　要：为了提升信息接入容量和信号收发质量,异构无源光接入网络中的远端基站单元越来越趋于微型化和密集化。光纤传能(PWoF)技术通过光纤将能量输送至远端单元,有望成为接入端供电的首选方案。在无源光接入网络中集成PWoF技术,可在单根光纤上同时传输信息与能量,具有一定的实际应用价值。综述了在无源光接入网络中应用不同波分复用、空分复用结构的PWoF方案,并比较分析了各技术方案的应用特点、实现功能和研究进展,最后探讨了PWoF在其演进过程中遇到的挑战以及前景展望。To enhance the information access capacity and signal reception and transmission quality,the remote base station units in heterogeneous passive optical access networks are increasingly becoming miniaturized and densely distributed.Photonic wireless power over fiber(PWoF)technology,which transmits energy via optical fiber to the remote unit,is expected to be the preferred solution for powering the access end.Integrating PWoF technology into passive optical access networks can transmit information and energy simultaneously on a single optical fiber,with certain practical application value.This paper reviews different wavelength-division multiplexing and space-division multiplexing structures of PWoF schemes in passive optical access networks,compares and analyzes the application features,functional realization,and research progress of each technology scheme,and finally discusses the challenges faced by PWoF in its evolution process and prospects.
