Multichannel Data Signals and Power Transmission by Power-Over-Fiber Using a Double-Clad Fiber

This letter presents multichannel data signals and feed light transmission based on power-over-fiber using a double-clad fiber (DCF). To demonstrate the feasibility of this technique, we experimentally demonstrate simultaneous data signals and feed light transmission using a DCF link. The data signals consist of a single-channel analog signal and four-channel digital signals with each having a channel spacing of 100 GHz. The feed light has a maximum power of 60 W and delivers the feed light to a remote unit where it is converted into electrical power using multiple high-power photovoltaic converters. In this letter, we successfully achieve good transmission performance of the DCF for all the analog and digital signals and over 7-Watt electrical power delivery, for the first time.
