A multifunctional optical power attenuation meter in fiber optic cables for widespread use is proposed in this article. The main feature of the proposed meter is the ability to perform of diagnostics of mechanical damage of fiber-optic communication lines and determine the attenuation degree of a signal in the fiber-optic path in the spectral ranges of 1270-1340 nm and 1520-1580 nm, as well as the measurement of voltage, current and resistance in electrical circuits. The possibility of using the meter for diagnostics of onboard fiber-optic communication lines is justified.
