Power Over Fiber for Phone Charging Application

Power over fiber is an emerging technology that utilizes fiber as an alternative medium for power delivery. The power over fiber application diversifies across sensors, internet of things, medical devices, and 5G cell applications. Nevertheless, collating the system design to achieve an optimum power system efficiency has appeared to be a challenging approach. This research work aims to demonstrate the feasibility of power transmission across 100 m- 300 m of multimode fiber for phone charging applications with 7.23% of power conversion efficiency. Experimental result has also demonstrated the power system efficiency differences across three types of multimode fiber. The testbed development of proof of concept could be further utilized for other power delivery applications.
