Abstract :
This contribution shows two well known methods estimating fog attenuation on free space optics (FSO) links. First one derives relationship between meteorological visibility and FSO link attenuation using the similarity with radio link propagation. The second method is based on light scattering solution in the fog volume after Van de Hulst. We proved that Mie scattering in Mie region corresponds to the situation in fog. Some properties of fog attenuation are shown.
