文摘

In this paper, we propose and verify a novel hierarchical radio-over-fiber (RoF) system with multiple base-station groups (BSGs). The proposed RoF system has a two-stage structure to provide the access of multiple services for each BS in BSGs, utilizing the scalable generation of multi-frequency millimeter-waves (MMWs). By using the four-wave mixing (FWM) effect in a semiconductor optical amplifier (SOA), multi-frequency MMWs can be generated with the scalability. The obtained results successfully verify the feasibility of our proposed multi-service access RoF system with BSGs.
