In this paper the availability of Free-Space Optical (FSO)
systems is studied. In order to create mathematical model
and calculate systems availability, meteorological data from
different geographic regions is used to obtain statistical
model of the atmospheric visibility SM. Utilizing the
cumulative distribution functions (CDF) of SM and the
statistical distribution of the misalignments (??) between
the laser beam axis and the center of the receiving antenna,
a method for calculating FSO availability is proposed.
Based on the derived analytical expressions, numerical
results are obtained and FSO availability is analyzed.
