Exploration of Hybrid FSO/RF Availabilities in Optical Wireless System

In this paper a more practical solution has investigate by extend the range of availability through FSO back-up link with a radio frequency (RF) link of lower data rate. This paper investigate the technical advantages of integrating FSO and RF communication systems to get availability of 99.999% to expand a new system called hybrid/dual RF/FSOF system. Analysis shows that a consequences of rain and fog have an effect on the RF and FSO links severally however not at the same time and barely occur at the same time to grant the choice to build up new hybrid FSO/RF system
