FIELD: measuring equipment.
SUBSTANCE: invention relates to measuring equipment using optical fiber, namely to fiber-optic security detectors, as well as to products, methods, and means related to fiber-optic security detectors and their aspects. A fiber-optic security detector contains a hardware delay line, which is an optical delay line for the fiber-optic security detector, made by means of connection into an optical circuit of reserve cores of a fiber-optic cable.
EFFECT: simplification of a mounting process and increase in a mounting speed, as well as increase in general operational reliability of a fiber-optic security detector, in particular, due to elimination from its composition of weakly protected compensation coils necessary for compensation of the length of fibers of a sensitive element; implementation by the invention of its purpose.
