Power-over-Fiber Technologies for Radio-over-Fiber Networks

Abstract

In future radio-over-fiber networks, a huge number of distributed remote antenna units are required to provide various kinds of communication services. Power-over-fiber, which delivers the power required for driving distributed remote antenna units into optical fibers, is an attractive technology to provide cost-effective installation, operation, and maintenance and achieve the power saving in the entire networks. This paper introduces our recent works on power-over-fiber technologies for remote antenna units in radio-over-fiber networks.
