Abstract

Specific demands of providing power to equipment in remote areas or hazardous environments, including populated areas, requiring high throughputs and ultra-low latency in beyond 5G (B5G) mobile communications that are based on Radio over Fiber (RoF) have made Power over Fiber (PoF) attractive. This paper reviews a breakthrough of a long-distance hollow core fiber (HCF) fronthaul (up to 11.1 km) able to meet the requirements of B5G optical mobile networks, where the transmission medium is common to both 5G NR and PoF signals. This work is placed in context and compared with results provided by other authors, showing the relevance of the outcomes and subsequent future possibilities. It also creates a discussion in which the performance of other fiber technologies may be compared, as new B5G fronthauls with special attention paid to transmission in a single fiber, avoiding noise transfer between high power laser PoF source and 5G-NR data that affects the signal quality. PoF energy delivery efficiencies are also analyzed, achieving up to 9.9 % efficiency (from launched optical power to electrical power on the load) for a 3.1 km HCF and 0.9 % for a 11.1 km HCF. The PoF signal is used to supply a Bluetooth Low-Energy load.

光子学突破2024:B5G无线功率光纤前传的进展

为偏远地区或危险环境（包括人口稠密地区）的设备提供电力的特定需求，需要基于光纤无线电（RoF）的超5G （B5G）移动通信的高吞吐量和超低延迟，使得光纤供电（PoF）具有吸引力。本文综述了一种能够满足B5G光移动网络要求的长距离空芯光纤（HCF）前传（高达11.1公里）的突破，该网络的传输介质为5G NR和PoF信号。这项工作被置于上下文中，并与其他作者提供的结果进行比较，显示结果的相关性和随后的未来可能性。它还创建了一个讨论，可以比较其他光纤技术的性能，因为新的B5G前沿技术特别关注在单光纤中传输，避免高功率激光PoF源和5G-NR数据之间影响信号质量的噪声传输。PoF的能量输送效率也进行了分析，在3.1公里的HCF下达到9.9%的效率（从发射的光功率到负载上的电能），在11.1公里的HCF下达到0.9%。PoF信号用于提供蓝牙低功耗负载。
