A cable is provided for detecting tampering thereof. The cable has at least one copper signal cable, a binder, an inner jacket, an armor, and at least one optical fiber sensor element, disposed within the cable. The at least one optical fiber sensor element is configured attenuate under stress to the cable, sufficient to detect a breach or tapping of the copper signal cable therein.

Cable with fiber optic sensor elements

A cable is provided for detecting tampering thereof. The cable has at least two copper signal cables, at least one hollow buffer tubes located abutting the two copper signal cables, an inner jacket, an armor, and at least one loose tube optical fiber sensor element disposed within the cable in a configuration that subjects the optical fiber sensor to external conditions. The at least one loose tube optical fiber sensor element is located between and abutting at least one of the copper signal cables and the at least one adjacent hollow buffer tube. The at least one loose tube optical fiber sensor element is configured attenuate under changes in the external conditions.
