FIELD: radio engineering, communication.
SUBSTANCE: device for integrated inspection of fiber-optic lines comprises an optical transmitter, an optical switch, an optical output of which is the output of the fiber-optic line, and a control input is connected with the microcontroller control output, the signal output of which is connected to the input of the alarm device, an optical demultiplexer and series connected an optical multiplexer, a circulator, a first photodiode and a first logarithmic amplifier.
EFFECT: improving the quality of inspection and ensuring the operation of the device in a wide dynamic range of transmission between the poles of fiber-optic lines without adjustment depending on losses in fiber-optic lines.
