Reference Frequency Signal Transfer to a VLBI Telescope Using an Optical Fiber Line

Transactions of IAA RAS, issue 43, 145–150 (2017)

Keywords: VLBI, stability of the reference frequency, optical fiber

Abstract

The article gives the results of a reference frequency signal transfer system operating with the RT-13 and the RT-32 telescopes via optical fiber lines. It shows that the phase of the transmitted reference signal depends on external influences, such as antenna rotation and ambient temperature changes. Also, we have worked out the principles for transferring reference frequencies to each of the devices located in different places of the radio telescope, with the possibility of measuring the phase changes in the transmission lines with 1ps accuracy.
