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