Radio over Free Space Optics (Ro-FSO) technology provides a promising solution for future wireless network, offering high data transmission compared to RF technology. In this paper, performance of double sideband - suppressed carrier based Ro-FSO system under various weather conditions is investigated. It transmits two RF signals at 10 and 15 GHz over an optical wireless channel of 1 km. At transmitter Mach Zehnder modulator is used for both carrier suppression and signal modulation. At the receiver, delay interferometer is used for separation of RF signal having delay of 0.1ns.
