AUTOMATED EQUALIZER OF OUTPUT SIGNAL LEVELS OF OPTICAL AMPLIFIERS OF MULTICHANNEL SYSTEMS Russian patent published in 2018 - IPC H03G5/00 H04J14/00 

FIELD: physics.

SUBSTANCE: essence of the proposed invention is to use the branch devices based on micro resonators in the signal fibre, after the chain amplifier, coupled with the micro actuators controlled by the electronic circuits that use the signals of the photodetectors-sensors of the power level distribution in the signal fibre to produce commands controlling the position of the micro actuators, with the purpose of automatic adjustment of the power levels across the operating range of the equalizer by changing the connection of the micro resonators with a signal fibre.

EFFECT: possibility of constructing a universal equalizer, operable without the individual configuration with any type of the optical amplifier, the automatic alignment operations of the power levels passing through the signal fibre, in the framework of the project working range of the transmitted signals and providing the technological capabilities of the integrated implementation of the device design, with a small amount of the power consumption and the possibility of the remote control of the linear signal uniformity at the amplifier output when embedded in the telemechanic system algorithm.
