FIELD: physics.
SUBSTANCE: apparatus comprises a reference signal generator, signal generators, a multiplexer, an optical transmitter, an optical fibre, an optical receiver, radio-frequency dividers, a high-pass filter, a controlled phase shifter, filters, a frequency converter, a phase detector and a scaling amplifier. The apparatus includes a fourth signal generator, a radio-frequency divider, a trimming phase shifter and a controlled attenuator; a heterodyne and one of the filters and converters are excluded; the generators are synchronised with the reference signal generator.
EFFECT: high phase stability, accuracy and reliability of transmitting a high-frequency analogue signal through the fibre-optic link.
