Next generation Free Space Optics system for ubiquitous communications

Free Space Optics (FSO) is being realized as an alternative means to compensate and/or replace the traditional optical communications in many applications where the fiber cable is not available. The next generation FSO systems in which the propagated signal after trans-mission over freespace is directly coupled into a single mode fiber have attracted much interest recently. However, the system performance is highly affected by the atmospheric environment, especially the atmospheric turbulence due to the random change in the air temperature and pres-sure. In this paper, we present the propagation characteristics of a newly developed Radio on FSO (RoFSO) system based on next generation FSO technology capable of transparent transmission of multiple wireless signals under effects of atmosphere turbulence. The system performance enhancement using atmospheric turbulence mitigation techniques will also be outlined.
