Radio On Fiber (ROF) is an optical analog technique for transmitting RF signals. With ROF systems, the base station conflguration is simple and independent of the modulation format and protocol. This advantage means that ROF is expected to become a useful way of realizing ∞exible 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 60GHz band ROF access system, which realizes a su-cient optical link budget with a simple system conflguration. |
