自由空间光（FSO）通信由于具有更宽的带宽、免许可频带、更高的空间重用和增强的安全性而成为比射频（RF）通信更有吸引力的选择。带内全双工FSO（IBFD-FSO）收发器可确保（在某些情况下可增强）这些功能，从而实现智能通信和物联网（IoT）应用的未来愿景。尽管IBFDFSO收发器理论上可以使网络容量增加一倍，但总体性能和容量受到干扰和光反馈的限制。在本文中，我们提出了一个概念验证原型的IBFD-FSO收发器通过实施隔离技术，以减少光反馈。我们证明了隔离技术和性能的有效性，通过使用现成的组件的试验台实验。
Free-Space-Optical (FSO) communication has become an attractive option over Radio Frequency (RF) communication due to having broader bandwidth, unlicensed band, higher spatial reuse, and enhanced security. In-band full-duplex FSO (IBFD-FSO) transceivers ensure, in some cases enhance, these features enabling future vision of smart communication and Internet-of-Things (IoT) applications. Even though IBFDFSO transceivers can double the network capacity theoretically, overall performance and capacity is limited by interference and optical feedback. In this paper, we present a proof-ofconcept prototype of IBFD-FSO transceiver by implementing isolation technique to reduce optical feedback. We demonstrate the effectiveness of the isolation technique and performance through test-bed experiments using off-the-shelf components.
