Abstract

In this paper we present the design concept and experimental evaluation results of a newly developed DWDM Radio on Free Space Optics (RoFSO) system capable of transmitting simultaneously multiple RF service signals. The system performance is evaluated under effects of atmospheric turbulence over 1-km free-space transmission. 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. An initial attempt to estimate an additional link margin to compensate for tracking error loss is also presented. Finally, we evaluate the performance of heterogeneous wireless signals after being transmitted over the system. We verify that the system can provide a stable connection for heterogeneous wireless services especially in the absence of strong atmospheric turbulence.
