title: 60 W power-over-fiber feed using double-clad fibers for radio-over-fiber systems with optically powered remote antenna units.
abstract: We experimentally demonstrated the ability to feed 60 W of optical power into a power-over-fiber link using a double-clad fiber for radio-over-fiber systems with optically powered remote antenna units. In order to improve the available optical feed power and the power transmission efficiency of the power-over-fiber link, we have designed a specially customized tapered fiber bundle divider for the remote antenna unit. We demonstrated, for the first time, bidirectional radio-over-fiber transmission over a 300 m double-clad fiber with an improved power transmission efficiency and optical power feeding up to 60 W input.
