This article presents simultaneous data and power transmission systems using a double-clad fiber (DCF). In future radio-over-fiber (RoF) networks, a large number of remote antenna units (RAUs) will be required to provide various kinds of mobile communication services. Power-over-fiber (PWoF), which delivers electrical power to drive the RAUs in optical fibers, is an attractive technique that offers cost-effective installation, operation, and maintenance of RAUs, and achieves the power savings across the entire RoF networks. In particular, the use of double-clad fibers (DCFs), which consist of a single-mode (SM) core and an inner cladding that surrounds the SM core, are useful for much higher power transmission than conventional PWoF techniques. Along the DCF link, optical data signals are transmitted into the SM core, whereas high-power feed light for optical powering is transmitted into the inner cladding, which has a core area that is approximately 240 times larger core area than that of conventional SM cores. In this article, we experimentally demonstrate a PWoF feed with up to 150-W of power using a 1-km DCF. To show the feasibility of the PWoF system, we investigate the bend performance and temperature characteristics of the DCF link. We also evaluate data and power transmission performance under the 150-W PWoF feed in the DCF link.

使用双包层光纤的 150W 光纤供电

本文介绍了使用双包层光纤 (DCF) 的同步数据和电力传输系统。在未来的光纤无线电 (RoF) 网络中，将需要大量的远程天线单元 (RAU) 来提供各种移动通信服务。光纤供电 (PWoF) 提供电力以驱动光纤中的 RAU，是一种极具吸引力的技术，可提供具有成本效益的 RAU 安装、操作和维护，并实现整个 RoF 网络的节能。特别是，双包层光纤 (DCF) 的使用由单模 (SM) 纤芯和围绕 SM 纤芯的内包层组成，可用于实现比传统 PWoF 技术高得多的功率传输。沿着 DCF 链路，光数据信号被传输到 SM 核心，而用于光供电的高功率馈送光传输到内包层，其纤芯面积比传统 SM 纤芯的纤芯面积大约 240 倍。在本文中，我们使用 1 公里 DCF 通过实验演示了功率高达 150 W 的 PWoF 馈电。为了展示 PWoF 系统的可行性，我们研究了 DCF 链路的弯曲性能和温度特性。我们还评估了 DCF 链路中 150-W PWoF 馈电下的数据和电力传输性能。我们研究了 DCF 链路的弯曲性能和温度特性。我们还评估了 DCF 链路中 150-W PWoF 馈电下的数据和电力传输性能。我们研究了 DCF 链路的弯曲性能和温度特性。我们还评估了 DCF 链路中 150-W PWoF 馈电下的数据和电力传输性能。
