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 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 detector is wound, wherein the reel contains a means for fixing a coupling of the mentioned linear part on its sidewalls, wherein the mentioned coupling contains splitters of the Mach-Cender interferometer placed in it, wherein the reel is made with the possibility of removing it from the container device for winding the linear part of another detector on it.
EFFECT: ensuring uniform sensitivity, as well as increasing the reliability of a security fiber-optic detector, while simplifying the installation and speeding up the installation process of detector components, as well as ensuring the possibility of installation using a motor vehicle or using a mechanized laying method, as well as the implementation by the invention of its purpose.
