FIELD: fibre optic technologies.
SUBSTANCE: invention relates to measuring technology using optical fibre, to fibre optic security detectors, as well as to products, methods and means related to fibre optic security detectors and their aspects.
EFFECT: increasing the sensitivity of a security fibre-optic detector by laying the cable of the sensing element on the elements of the fence in the form of a smoothly curving shape that fastens the wires of the wire fence, strengthening the fence itself and eliminating the possibility of an imperceptible penetration of the intruder through the fence by pushing the wire threads and forming a hole in the fence; increasing the overall operational reliability of a security fibre-optic detector, in particular, due to the exclusion from its composition of weakly protected compensation coils necessary to compensate for the length of the fibres of the sensitive element, the implementation of the purpose.
