FIELD: measurement.
SUBSTANCE: invention relates to measuring equipment using optical fibre, namely to fibre-optic security detectors. Drum of container device for assembly of linear part for detector of security fibre-optic is made with possibility of rotation on axis of drum, on which the fibre-optic cable of the linear part of the security fibre-optic detector is wound. Said drum comprises means to secure said linear part on its sidewalls while said coupling comprises Michelson interferometer splitters.
EFFECT: simplification and acceleration of installation process.
