The way of reference frequency and time scales transmission via optical fiber is describes in the article. Transmission system is designed to transfer reference signals from clock to remote object’s users. It uses two standard communication fiber optical links. One optical channel is used for transfer of reference frequency signal. Second channel is used to compare time scales of remote objects. The results of experimental studies of the transmission uncertainly of reference frequency and time signals using fiber-optic communication lines are listed. The method of radio frequency reference signal transmission by optical fiber line is represented. The scheme of electronic compensation of reference 100 MHz signal phase perturbations in optical fiber is described. The experimental results of Allan deviation measurements of 100 MHz reference signal transmitted to the remote end of fiber line 100 km long are presented
