In this work authors present computational modeling results of optical signals passage near the receiving
sites made in ANSYS program complex. Laser beam is split into several filaments due to the phenomenon
of turbulence. Due to the fact that uneven distribution of air refraction coefficients occurs near the receiving
sites of optical signal receiving devices in the atmosphere, laser beams are split near the receiving sites. It
means that requirements for the receiving sites of optical signals should be increased. To solve the problem
with phenomenon of turbulence, several laser transmitters and receivers at different wavelengths should be
installed in laser beam propagation installations. It increases the speed of information transfer and the reliability
of the devices.
Key words: turbulence, optical signals, laser radiation, beam path, optical beam splitting.
