Abstract


Free-space optical (FSO) communications, also known as wireless optical communications, is a cost-effective and high bandwidth access technique and has compelling economic advantages. With the potential high-data-rate capacity, low cost and particularly wide bandwidth on unregulated spectrum, FSO communications is an attractive solution for the “last mile” problem to bridge the gap between the end user and the fiber-optic infrastructure already in place. However, also other structural conditions atmospheric losses fairly affect the signal gain communication due to the fact that communication medium is an air. In this study, a FSO component is designed using Matlab software for geometrical and atmospheric losses and integrated into OptSim 4.0 software to analyze the FSO system. Somewhat apart, signal attenuations due to the atmosphere conditions are eliminated using Erbium Doped Fiber Amplifier (EDFA). In this way, signal transmission distance is increased in comparison with the traditional FSO systems.
