Abstract

Free space optics represents a fast and economical method to transmit digital data at the speed of the order of the Gbps at a distance of a few kilometers. The major limitation is the atmospheric attenuation, especially fog, which can affect the quality of transmission, transfer rate and transmission distance. A useful metric to monitorize the processes is the BER factor. This paper proposes a combination of adaptive optics that use multiple heads of transmission which are focused simultaneously on a single photodetector at the receiver end, in order to provide redundancy and to sustain a minimum data-rate transfer and/or assuring a transmission distance at an acceptable BER. It is assessed, through the simulation, the optimal (technically and economically) number of optical transmitters for which we get a real quality improvement of the transmission for a given bitrate-distance factors.
