RoF(radio-over-fiber) technology combines microwave radiofrequency technology with photonics technology, and simultaneously embodies the technical features of "high speed" of optical communication and "mobility" of wireless communication. It greatly reduces the energy consumption of wireless network, representing the future development direction of optical networks and wireless networks. This paper begins with the domestic and foreign state of the RoF technology research and application, then focuses on the challenges that the ROF technology currently faces, and finally gives its future R/D direction on the basis of investigation of ROF key technologies.
