One of the alternative applications of microwave photonics is hybrid Radio over Fiber (RoF) and Visible Light Communication (VLC) systems, which combines the advantages of radio frequency and optical communication together with wireless optical communication. In this paper, a hybrid radio over optical fiber and VLC system has been designed and simulated using OptiSystem Software by applying a Continuous Wave (CW) Laser at wavelength 1550 nm for optical fiber communication and 450 nm Visible Light LED for VLC system. The 8 Gbps of data was transmitted over 40 km of the fiber length and 3 m of VLC link with a Millimeter Wave (mmWave) frequency at 40 GHz. The proposed design system is analyzed based on the effect when varies the propagation distance for both fiber and VLC. The results show that as the number of fiber lengths increases, the BER performance is degraded until threshold limit 10−9. It is also shown that the proposed hybrid design system is working well even at a very high data rate of 8 Gbps for each user channel. The results also demonstrate that Non-Return Zero (NRZ) modulation technique has contributed to the better performance of the systems compared to Return Zero (RZ).
