FIELD: communication technologies.
SUBSTANCE: invention relates to communication technology; it can be used in systems for the transmission of analog signals using time and frequency channel compaction. The device contains: the first and the second laser modules, the first and the second electro-optical Mach-Zander modulators (hereinafter – MZM), a controller, an optical multiplexer; the controller is connected to shift electrodes of the first and the second MZM, a source of a high-frequency information electrical signal, an acousto-optic modulator (AOM), an optical demultiplexer, optical delay lines, and an optical radiation receiver.
EFFECT: increase in the noise immunity by limiting the illumination time of the optical radiation receiver with continuous adjustment and control of the position of the working point.
