It is noted that it is often necessary to branch a part of the output power of an optical radiation source from the main transmission channel in order to control, measure, or receive a feedback signal intended to control the level of the output power of the optical radiation source, as well as to separate or combine the optical radiation flow. Based on the analysis of existing works, a multifunctional fiber-optic sensor has been developed that allows connecting one of the optical transmission modules with a low attenuation coefficient, collecting information corresponding to the level of branched optical radiation, determining the fact and mass of an object of unauthorized penetration depending on the intensity of branched optical radiation, and automatically adjusting the output power of branched optical radiation through a feedback circuit.
