Technical Trends in Millimeter-wave Band Radio-On-Fiber Access SystemTomohiro Taniguchi, Naoya Sakurai, Hideaki Kimura, and Kiyomi Kumozaki doi:10.2529/PIERS080905073512 Downloads: 654 Abstract:Radio On Fiber (ROF) is an optical analog technique for transmitting RF signals. With ROF systems, the base station configuration is simple and independent of the modulation format and protocol. This advantage means that ROF is expected to become a useful way of realizing flexible and high capacity access networks. This paper reviews recent technical trends in ROF access systems, focusing especially on the millimeter-wave band. In addition, this paper describes our proposal based on an optical heterodyne technique for a 60 GHz band ROF access system, which realizes a sufficient optical link budget with a simple system configuration.References:1. http://www.ftthcouncil.org. 2.
