Maximizing Throughput of Free Space Optics Communication link with Array of Receivers

Abstract

This paper analyse the integration of optical amplifiers and optical filters with free space optics link (FSO) for improving its performance. These components play a crucial role for enhancing and conserving pulse shape of transmitted signal. Different amplifiers and filters are critically investigated to improve the optical wireless link output. The high quality link is analysed to increase its acceptability in terms of bit error rate, Q factor and height of eye diagram. Further, the optimal combination of an amplifier and a filter is chosen so as to give the best output for a particular application of FSO. To further enhance the versatility of the designed optical link the performance of FSO link has also been analysed using array of receivers and under different weather conditions. After simulations it is found that the usage of specific filter – amplifier combination significantly improves the performance of FSO link.
