Beschreibung
Zusammenfassung:	The device has at least one multimode fiber optic cable (3) for laser light and a device to measure the propagation time and intensity of the backscattered light, to determine localized temperature anomalies along the cable. At least one monomode optical fiber cable (2) for message transfer forms an uncladded connection arrangement with a push and pull arrangement (1). The cable is laid in the pipe with pressure-tight entry and exit guide connections. Independent claims are included for a method for installing a fiber bundle cable arrangement for incorporation in the device and a unit for installing the fiber bundle cable arrangement.
