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. The claimed reel with a fiber-optic cable is made with the possibility of installation on an unwinding device of a cable layer with V-shaped plough for mechanized laying of the fiber-optic cable into the soil, in which water is supplied to a channel for input of flexible linear elements to provide better contact of the cable with the soil, and subsequent ramming is performed with the cable layer after laying is finished; and/or cable laying is performed along a curved trajectory with alternating change in the direction of a trajectory bending radius in such a way that to provide cable tension during laying.
EFFECT: acceleration of mounting of a sensitive element of a fiber-optic security detector, as well as increase in its sensitivity, and provision of uniformity of its sensitivity due to provision of tight fit of a cable to the soil in a soil slot formed by lowering the upper part of a cut soil formation on the previous base with subsequent compaction directly in laying the cable of the sensitive element, using V-shaped plough; as well as implementation by the invention of its purpose.
