Variants of construction of systems intended for comparison of time scales of remote standards and transmission of reference RF signals over fiber-optic lines of different lengths are proposed. The principle of operation of the parts of the complex of equipment for comparing of time scales of standards and for stable RF transfer over optical fiber is described. The calculation of the error in measuring the divergence of the time scales of remote standards performed with the help of the proposed equipment is given. The results of experimental investigations of the components of the complex in the transmission of reference signals over a distance of up to 200 km are presented.

Key words: transmission of reference RF signals over fiber-optic lines, comparison of time scales of remote standards.
