Impact of Beam Divergence on the Performance of Free Space Optical System

Abstract

Free space optical communication system (FSO) is a potential solution for increasing bandwidth demands. The FSO has a capability to provide high speed data communication, economic and quick deployable. With recent advances and interest in Free Space Optics (FSO) for commercial deployments, a proper understanding of optical signal propagation in different atmospheric conditions has become essential. Although FSO has several advantages, but at the same time FSO faces a major challenge from scintillation introduced by atmospheric turbulence but improvement in performance of FSO Link has been observed with the use of small beam divergence angles. In this paper, the simulation performance investigation of varying beam divergence angle for FSO system is carried out. The performances are analyzed in terms of bit error rate (BER), Quality factor (Q) and eye diagrams.
