FIELD: measuring equipment.
SUBSTANCE: invention relates to measuring equipment using optical fibre. The technical result is achieved by using a container apparatus for assembling the linear part for the fibre-optic security detector, constituting a container with a cover, containing a base with an axis of rotation, secured whereon is a rotating drum whereon a fibre-optic cable of the linear part of the fibre-optic security detector is wound, wherein the drum comprises a tool for securing the connecting coupling of said linear part to the side walls thereof, wherein said coupling comprises splitters of a Sagnac interferometer and splitters of Mach-Zehnder interferometer placed therein.
EFFECT: increase in the reliability of the fibre-optic security detector.
