In this paper, we present the design concept and performance evaluation results of a newly developed DWDM Radio over Free-Space Optics (RoFSO) system capable of transmitting multiple wireless service signals simultaneously. The system performance is evaluated over 1-km free-space transmission under effects of atmospheric turbulence and attenuation. Effectiveness of a proposed tracking scheme used to mitigate beam angle-of-arrival (AOA) effect and the viability of the communication system using a specially designed optical antenna are illustrated. The properties of free-space propagation under influences of atmospheric turbulence and attenuation are characterized. We then present the performance of wireless signals after being transmitted over the system. We verify that the system can provide a stable connection for wireless services especially with the absence of strong atmospheric turbulence and heavy rain. Finally, we present a consideration on the system application by indicating the possible applicable link range based on the system designed power margin and the tracking system efficiency. The proposed system is expected to be an alternative or be combined with wireless over fiber (WoF) to realize a universal platform for ubiquitous and high throughput wireless communications.
