Abstract

Simultaneous transmission of high-speed data and high-power energy in optical networks is merging radio-over-fiber (RoF) and power-over-fiber (PoF) concepts. In this work, we present an approach to evaluate the analog performance of RoF-PoF systems, based on figures of merit used in microwave photonics. Different optical links are proposed to transmit and receive RF signals remotely, while using the same fiber to supply power to electronic sensors. We compare measured values with theoretical predictions in two experimental setups. Both employ a 1480 nm power signal and a 1550 nm data signal propagating together over a 10 km single-mode fiber (SMF). Analytical results are in good agreement with measurements, as long as power level does not exceed a specific threshold, when system instabilities arise. Optical power delivered to the optical-electrical converter is sufficient to feed low consumption devices, proving the effectiveness of such approaches in remote applications.

拉曼激光器光纤供电链路中射频信号的传输和接收

光网络中高速数据和高功率能量的同时传输融合了光纤无线电(RoF)和光纤电力(PoF)的概念。在这项工作中，我们提出了一种基于微波光子学中使用的优点数来评估RoF-PoF系统模拟性能的方法。提出了不同的光链路来远程发送和接收射频信号，同时使用相同的光纤为电子传感器供电。在两个实验装置中，我们将测量值与理论预测值进行比较。两者都采用1480nm功率信号和1550nm数据信号，通过10公里单模光纤(SMF)一起传播。当系统出现不稳定时，只要功率水平不超过特定阈值，分析结果与测量结果很好地吻合。传输到光电转换器的光功率足以为低功耗设备供电，证明了这种方法在远程应用中的有效性。
