Abstract: The microwave photonic technology-based Ultra-Wideband (UWB ) Radio over Fiber (RoF ) system is an important solution to the future low-cost and high-performance ultra-wideband wireless access network. Much research work has been done in this field with abundant results. This article introduces the RoF system that is based on the all-optical vector modulation technology to further enhance signal ’s spectrum efficiency; the full-duplex RoF system that is based on the millimeter wave Phase-Shift Keying (PSK ) modulation to greatly simplify base station structure and fiber layout; and the RoF system that is based on multi-service mixed transmission to carry the service with both wired signal and several wireless signals. The article also presents an RoF-based high-definition video transmission platform
