Patent number: 10755837Abstract: 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.Type: GrantFiled: April 11, 2019Date of Patent: August 25, 2020Assignee: NEXANSInventors: David Keller, Donald Stevens, Pritesh Majmundar, Norman Andrew Punch, Jr., Rakesh Sambaraju, Dan Rouse, Randie Yoder

Patent number: 10741304Abstract: 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.Type: GrantFiled: June 20, 2019Date of Patent: August 11, 2020Assignee: NEXANSInventors: David Keller, Donald Stevens, Pritesh Majmundar, Norman Andrew Punch, Jr., Rakesh Sambaraju, Dan Rouse, Randie Yoder

Patent number: 8855455Abstract: An arrangement provides for an optical fiber cable having a plurality of fiber optic elements including a glass portion and a UV optical coating portion. A plurality of buffer tubes each contain one or more of the plurality of optical fibers made of a fire retardant polymer. A jacket surrounds the buffer tubes also made of a fire retardant polymer. The fire retardant polymers for the plurality of buffer tubes and for the jacket are selected from PVDF (PolyVinyliDene Fluoride) or FRPVC (Fire Resistance Poly Vinyl Chloride). The ratio of total polymer to UV optical coating of the fiber optic elements, by area, is substantially in the range of 5:1 to 9:1.Type: GrantFiled: November 23, 2011Date of Patent: October 7, 2014Assignee: NexansInventors: David Keller, Christopher Raynor, Terry Gooch, Randie Yoder, Dan Rouse, Andrew Punch

Patent number: 6370305Abstract: An optical fiber array (20,40) comprising at least one subunit (26,46) including at least one optical fiber (22) therein surrounded by a respective subunit matrix (23,43) having a subunit matrix modulus characteristic. The optical fiber array (20,40) includes a common matrix (24,44) disposed adjacent to the at least one subunit (26,46) and having a common matrix modulus characteristic. A subunit/common matrix modulus ratio being defined as a ratio of the subunit matrix modulus characteristic with respect to the common matrix modulus characteristic, the subunit/common matrix modulus ratio being greater than about 1.5:1. The optical fiber array (20,40) can include an adhesion zone (28,48) defining a controlled adhesion bond between the common and subunit matrices (24,26;44,46).Type: GrantFiled: May 14, 2001Date of Patent: April 9, 2002Inventors: Gregory A. Lochkovic, Norman Andrew Punch, Jr., Brunhilde Hagemeister
