The invention is related to the field of telecommunications, more specific to the optical sensors. Invention targets to develop sensor signal processing device with integrated optical time-domain reflectometer, to monitor object tehnical condition. Offered device consist of signal monitoring and analizing unit and optical transmition lines,with integrated optical FBG and net of intensity sensors. Invention differs with signal monitoring and analizing unit having optical time-domain reflectometer (1), superlumenestic diode SLED (2) and optical circulator (3) and to monitor and detect central frequencies of fiber Bragg net reflecting FBG sensor signal , the signal central frequencies detector (13) is used. Invented device offers to provide control of sensor network operation and it is compatible with wavelength division multiplexing-passive optical network systems.
