Abstract

In this paper, developing process of a DWDM (Dense Wavelength Division Multiplexing) Radio on Free Space Optics (RoFSO) system to transmit multiple radio services on a point-to-point optical wireless link is reported. The RoFSO is broadband RF optical wireless communication link with fiber-optic technologies. It can provide universal platform for heterogeneous radio entrance network, in especially rural area with no fiber infrastructure. The developed RoFSO transceiver can directly connect multiple radio-on-fiber(RoF) signals from an optical fiber to the air, and can receive an optical signal from the air into a fiber core. One of issues in designing an FSO link including optical scintillation, new analysis model is proposed in order to estimate its variation speed. By using proposed model, scintillation speed and their variance in experimental results are presented. Finally, increasing FSO distance due to the optical power allocation among four DWDM optical sources for each radio services under the power limitation of eye safety regulation based on spectrum mask test in indoor short range experiment is presented.
