Publication number: 20150253526Abstract: An optical communication cable includes a core, armor surrounding the core, a jacket surrounding and bonded to the armor, and a binder film also surrounding the core and interior to the armor. The core includes buffer tubes surrounding sets of optical fibers and a central strength member. The buffer tubes are stranded around the central strength member in a pattern of stranding including reversals in lay direction of the buffer tubes and the binder film holds the buffer tubes in position. The binder film is bonded to an interior of the armor, thereby providing a quick access capability to access the core via simultaneous removal of the binder film when the armor and jacket are removed.Type: ApplicationFiled: June 26, 2014Publication date: September 10, 2015Inventors: Mario Sergio Sandate Aguilar, Michael John Gimblet, Julian Latelle Greenwood, III, Warren Welborn McAlpine

Publication number: 20150241652Abstract: A fiber optic cable includes a core and a binder film surrounding the core. The core includes a central strength member and core elements, such as buffer tubes containing optical fibers, where the core elements are stranded around the central strength member in a pattern of stranding including reversals in lay direction of the core elements. The binder film is in radial tension around the core such that the binder film opposes outwardly transverse deflection of the core elements. Further, the binder film loads the core elements normally to the central strength member such that contact between the core elements and central strength member provides coupling there between, limiting axial migration of the core elements relative to the central strength member.Type: ApplicationFiled: September 23, 2013Publication date: August 27, 2015Inventors: Bradley Jerome Blazer, Rodney Maurice Burns, Julian Latelle Greenwood, Keith Aaron Greer, Warren Welborn McAlpine

Publication number: 20150110451Abstract: An optical communication cable includes a cable body, a plurality of core elements located within the cable body, a reinforcement layer surrounding the plurality of core elements within the cable body, and a film surrounding the plurality of core elements. At least one of the plurality of core elements includes an elongate optical transmission element. The film provides an inwardly directed force onto the core elements, and a surface of the film is bonded to the reinforcement layer.Type: ApplicationFiled: June 27, 2014Publication date: April 23, 2015Inventors: Bradley Jerome Blazer, Michael John Gimblet, Julian Latelle Greenwood, III, Jason Clay Lail, Warren Welborn McAlpine, Eric John Mozdy

Patent number: 8995809Abstract: Cables are constructed with discontinuities in the cable jacket that allow the jacket to be torn to provide access to the cable core. The discontinuities can be longitudinally extending strips of material in the cable jacket. The discontinuities allow a section of the cable jacket to be pulled away from a remainder of the jacket using a relatively low peel force.Type: GrantFiled: April 10, 2014Date of Patent: March 31, 2015Assignee: Corning Optical Communications LLCInventors: Michael John Gimblet, Julian Latelle Greenwood, III

Publication number: 20150043874Abstract: An optical communication cable includes a jacket, optical transmission elements, and armor. The jacket is mostly formed from a first material and includes an elongate member formed from a second material embedded in the first material. The jacket defines a channel in which the optical transmission elements are located. The armor includes a wrapped sheet having a lateral edge and is positioned around the optical transmission elements within the channel. The elongate member has an inner surface aligned with and located exterior to the lateral edge of the armor; and, when viewed in cross-section, the elongate member fully overlays and extends tangentially beyond the lateral edge. Accordingly, the elongate member provides an obstacle in the jacket that limits zippering through the jacket originating from the lateral edge. Further, the elongate member may double as a tear feature for quickly accessing contents of the cable interior to the jacket.Type: ApplicationFiled: December 7, 2013Publication date: February 12, 2015Applicant: Corning Cable Systems LLCInventors: Mario Sergio Sandate Aguilar, Michael John Gimblet, Julian Latelle Greenwood, III, Warren Welborn McAlpine

Publication number: 20140241678Abstract: A fiber optic cable assembly includes a distribution cable and a tether cable. The distribution cable includes a jacket having a generally flat profile such that the periphery of the distribution cable, when viewed in cross-section, includes two major surfaces of the jacket that are generally flat and are connected by arcuate end surfaces of the jacket. The jacket defines a cavity therein. Further, the distribution cable includes strength members embedded in the jacket and positioned on opposing sides of the cavity. The distribution cable includes a plurality of optical fibers extending through the cavity. The tether cable includes an optical fiber that is fusion spliced to one of the optical fibers of the distribution cable by way of an opening in a side of the jacket of the distribution cable.Type: ApplicationFiled: May 5, 2014Publication date: August 28, 2014Applicant: Corning Optical Communications LLCInventors: Anne Germaine Bringuier, Julian Latelle Greenwood, III, David Alan Seddon, Kimberly Dawn Slan, Kenneth Darrell Temple, JR.

Publication number: 20140212101Abstract: A fiber optic cable includes a jacket, a pair of strength members, and an optical fiber. The jacket has a cavity, a major dimension and a minor dimension, and a medial portion. The strength members are disposed on opposing sides of the cavity and impart a preferential bend characteristic to the cable. The at least one optical fiber is disposed within the cavity.
