FIELD: measuring equipment.
SUBSTANCE: invention relates to measuring equipment using optical fiber, namely to security fiber-optic detectors. A reel of a container device for assembling a linear part for a security fiber-optic detector is a reel made with the possibility of rotation on the axis, on which a fiber-optic cable of the linear part of the security fiber-optic detector is wound. The reel contains a means for fixing a coupling of the mentioned linear part on its side walls, and the mentioned coupling contains splitters of the Michelson interferometer and the Sagnac interferometer placed in it.
EFFECT: increasing the accuracy of determining the location of the impact on the sensitive element, ensuring uniform sensitivity of the sensitive part of the detector, increasing its reliability.
