摘要：

The paper presents some analyses of practical applications of free space optical communications. Its advantages as well as limitations are desribed comparising with other data transfer technologies. The potential of FSO links in relation to the development of 5G technology has also been indicated. The main part of the paper presents some preliminary tests results of RF/FSO hybrid data link constructed for the purposes of national defense and security. The concept of the construction is based on use of radiation sources and photodetection modules operated in the spectral range of 8-12 mu m. The performed tests of this hybrid link have confirmed its functionality and ability to work in different weather conditions The numerical calculations made it possible to estimate the SNR value of the developed optical transmission channel.
