Abstract

The trend of constant growth of requirements for the volume, speed, and degree of protection of information transmitted in communication networks determines the search and study of promising communication systems that provide a reliable high-speed communication channel in conditions of possible destructive external influences on communication lines. As such a prospective technology, the paper considers atmospheric optical communication implemented using serial optical terminals manufactured by Russian companies. The paper describes a universal approach to calculating the availability of an atmospheric communication channel taking into account the technical parameters of the terminals and meteorological parameters in the area of the terminals as well as optical losses due to the absorption and scattering of laser radiation that occur during the propagation of an optical signal through the atmosphere. For the first time, sets of dependencies of the distances of the atmospheric channel with specified availability factors for modern Russian terminals of free space optics were obtained taking into account a long-term archive of meteorological parameters of the cities that are part of 37 Federal Districts of the Russian Federation, taking into account new regions (Donetsk People's Republic, Lugansk People's Republic, and Zaporizhya and Kherson Regions).
