In this work, a hybrid architecture employing Single Mode Fiber (SMF) link followed by Free Space Optic (FSO) transmission and Visible Light Communication is investigated. FSO is incorporated in the system after optical fiber in order to serve optical network units wirelessly where deployment of optical fiber is tedious or impossible such as in hilly areas, intra educational buildings etc. Further, VLC is incorporated in the system to serve ONUs inside building with Light Fidelity. For optical fiber based users, data rate of 10 Gbps is provided over 25 km and total 8 ONUs are served at guaranteed 2.5 Gbps. FSO link after 25 km SMF and 450 m free space distance served additional 8 users at same bit rate as optical fiber users. For LiFi link, total bit rate of 1 Gbps has been achieved over 2 m link. Therefore, our proposed system has provisions for optical fiber based users, wireless FSO based ONUs and intra building ONUs.
