Simultaneous over 40-W electric power and optical data transmission using an optical fiber is demonstrated for optically powered remote antenna units in future mobile communication networks. In this article, to further increase the delivered electric power by power-over-fiber link using a double-clad fiber, we improve the link design to extract a higher feed light power from the double-clad fiber output. Furthermore, to increase the electric power for driving remote antenna units, we employ a specially customized photovoltaic power converter that directly converts optical power into electric power. The photovoltaic power converter can input a feed light with power of over 20 W and has a high optical-to-electrical conversion efficiency of over 50%. As a result, the combination of the improved power-over-fiber link design and the use of the photovoltaic power converter successfully achieves the electric power delivery of up to 43.7 W. This is the highest electric power delivery demonstration by power-over-fiber with optical data signals using a single optical fiber, to the best of the authors' knowledge.

使用光纤进行超过 40W 的电力和光数据传输


未来移动通信网络中的光供电远程天线单元演示了使用光纤同时进行超过 40W 的电力和光数据传输。在本文中，为了进一步增加使用双包层光纤的光纤供电链路所传输的电力，我们改进了链路设计，以从双包层光纤输出中提取更高的馈送光功率。此外，为了增加驱动远程天线单元的电力，我们采用了专门定制的光伏电力转换器，可直接将光功率转换为电力。该光伏功率转换器可输入20W以上功率的馈光，光电转换效率高达50％以上。结果，改进的光纤供电链路设计和光伏功率转换器的使用相结合，成功实现了高达43.7 W的电力传输。这是光纤供电的最高电力传输演示据作者所知，使用单根光纤传输光学数据信号。
