Power over Fiber for Internet of Things Application

Copper-based cables have limitation of distributing power safely and efficiently for Internet of Things (IoTs) application as well as during emergency conditions. This research paper aims to demonstrate the power over fiber (PoF) distribution system network in the short-haul distance, as an alternative to copper-based cable. The maximum efficiency obtained for the full system was 12% at 450 mA of laser driving current. The obtained results clearly demonstrated that as the laser driving current increases from 50 mA to 450 mA, overall efficiency of the system increases. The prototype was designed with a low power output where the main parameter that affects the overall efficiency system is the optical to electrical conversion module. Prototype results demonstrated the potential of PoF for low power distribution system.
