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: 9086556Abstract: A multi-tube optical fiber cable has a core with a first set of one or more optical fiber tubes, each having one or more optical fibers loosely arranged therein. The first set of tubes is constructed of a polymer having a low Young's constant modulus. The core also includes at least two strength members with a first binder arranged around the first set of optical fiber tubes and the strength members, where the first binder is substantially flat in shape such that there is no deformation of the first set of tubes, and where the strength members are offset from a central axis of the cable. The cable maintains a second set of a plurality of optical fiber tubes, each having one or more optical fibers loosely arranged therein, arranged around the outer circumference of the core.Type: GrantFiled: February 12, 2013Date of Patent: July 21, 2015Assignee: NEXANSInventors: David Keller, Randie Yoder, Paul Kroushl, Dan Rouse

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: 8639076Abstract: A fiber optic cable is provided with a plurality of buffer tubes each with one or more optical fibers, a plurality of strength members and a jacket. The fibers within the cable meet maximum attenuation of substantially 0.07 db increase when decreasing from ?23° C. to ?60° C.Type: GrantFiled: August 17, 2010Date of Patent: January 28, 2014Assignee: NexansInventors: David Keller, Paul Kroushl, Randie Yoder, Dan Rouse

Patent number: 8467645Abstract: An assembly of fiber optic elements includes at least two subunits, each of which has at least one fiber optic unit and a flat binder wrapped over the subunits into an arrangement. The at least two subunits are stranded in a S-Z arrangement at a first lay length and the binder is stranded over the subunits in a uni-directional helical lay at a second lay length. The payoff tension and the first lay length of the subunits, combined with a payoff tension and the second lay length of the binder are simultaneously sufficient to hold the subunits within the arrangement, while being loose enough to allow a single subunit to be removed without destroying the arrangement.Type: GrantFiled: July 30, 2010Date of Patent: June 18, 2013Assignee: NexansInventors: David Keller, Randie Yoder, Terry Gooch
