This article deals with few described loss which can appear in Free Space Optic (FSO) link. It is a misalignment loss which comes on by inaccurate installation of FSO heads. A calculation of this loss is based on power budget. The calculation of misalignment loss was done for professional FSO link which is installed in campus of VSB-Technical University of Ostrava. Results showed that a small misalignment...
This article is focused on the atmospheric turbulences and their effect on optical beam. The Free Space Optics link with atmospheric turbulences was created in software OptiSystem. The results given by software are compared with Andrews's method. Free Space Optics link worked at wavelengths 850 nm and 1550 nm.
