A dual optical wireless test link works with two different optical wavelengths in spectral windows of 850 nm and 1550 nm. The transceivers of the link are placed on the highest peak of the Czech Central Mountains (Milesovka Mountain) so that the transmission path is oriented almost in a vertical direction. The installation site is situated in a locality with the harshest climate in the Czech Republic with extreme attenuation conditions. The almost vertically oriented path of the link allows analyzing the impact of the different atmospheric layers on the signal transmission. The monitoring of the received power and the archiving of the appropriate data are constantly provided. The relationship between the link attenuation and the atmospheric visibility has been investigated. The results of this experiment are presented.
