With the advantages of large channel capacity, mobile access and wide covering range, Radio-over-fiber access technology will have immense potential in the field of next-generation access network. Recently high-definition television, Internet of Things and other services requier require a higher rate of access in communication network, even up to 10Gbps or above. In this paper, the key technology and core devices of 10Gbps or above Radio-over-fiber link are introduced and analyzed in the performance by comparing with those of low rate. We also emphasize the development of ROF technology and make analysis of performance on them based on the carriers of 60GHz, 120GHz,300GHz.The feasibility of 10Gbps-ROF application is verified with the corresponding instances.
