摘要： In order to ensure the normal operation of the overhead high voltage line, many sensors are arranged on the high-voltage towers to monitor the state of the high voltage cable. However, high-voltage towers cannot directly provide usable power and have strong electromagnetic interference, so special energy supply methods are needed. Compared with traditional methods such as voltage divider and solar power, power-over-fiber (PoF) technology can achieve a safer and more reliable energy supply due to the passive and anti-electromagnetic interference of optical fiber. In this paper, we propose an improved structure of the PoF receiving module to reduce the impact of the environment on the power supply. And we design a multi-core energy transmitting fiber for this structure. Compared with multiple single-core fibers, using multi-core fiber can increase system integration and reduce the cost and construction difficulty.

[IEEE 2019 IEEE XVth International Conference on the Perspective Technologies and Methods in MEMS Design (MEMSTECH) - Polyana, Ukraine (2019.5.22-2019.5.26)] 2019 IEEE XVth International Conference on the Perspective Technologies and Methods in MEMS Design (MEMSTECH) - Efficiency Evaluation of Photovoltaic Power Converters for Ultra-Low Power Supply Systems
摘要： Power-over-Fiber (PoF) is a very promising technique and recent technology development makes it applicable. However the cost of PoF is high since high powered laser, photovoltaic power converters and special optical fibers are used. In this paper the detailed efficiency evaluation of optical power supply system based on standard, low cost telecom components are given. Different semiconductor materials were characterized to build the most efficient supply system. The highest conversion efficiency of photodiode equal to 26.2% and the efficiency of whole system equal to 13% is achieved.

Design, Characterization, and Test of a Versatile Single-Mode Power-Over-Fiber and Communication System for Seafloor Observatories
摘要： A power-over-fiber (PoF) and communication system for extending a cabled seafloor observatory is demonstrated in this contribution. The system allows the cabled seafloor observatory to be linked, through a single optical fiber, to a sensor node located 8 km away. The PoF system is based on an optical architecture in which power and data propagate simultaneously on the same single-mode fiber. The Raman scattering effect is exploited to amplify the optical data signals and leads to the minimization of the sensor node power consumption. Versatile low power electronic interfaces have been developed to ensure compatibility with a wide range of marine sensors. A low-consumption field-programmable gate array and an energy-efficient microcontroller are used to develop the electronic interfaces. For an electrical input power of 31 W, up to 190 mW is recovered at the sensor node while a data bitrate of up to 3.6 Mb/s is achieved. The PoF system has been tested and validated for turbidity and acoustic measurement applications. The current study focuses on the electronic development and the validation of the PoF system.

摘要： We propose a multi-core fiber (MCFs) based concept which simultaneously use to generate millimeter wave (mm-wave) signal; a radio over fiber link; and a power over fiber link. In the proposed system, some cores of MCFs are used to generate mm-wave signal using an optoelectronic oscillator (OEO) topology, few of the cores are used to transport data modulated mm-wave signal through radio-over-fiber (RoF) technology while others are used to transmit optical power for biasing the amplifier in the remote antenna unit with help of power over fiber (PoF) technology and photonic power converter in a small cell architecture of the future 5G technology.
