150-W Power-Over-Fiber Using Double-Clad Fibers [PDF]

Journal of Lightwave Technology, 2020
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
