Abstract: A fiber optic cable includes a jacket forming a cavity therein, the jacket having an indentation on the exterior thereof that forms a ridge extending into the cavity along the length of the jacket; and a stack of fiber optic ribbons located in the cavity, each ribbon having a plurality of optical fibers arranged side-by-side with one another and coupled to one another in a common matrix, wherein corners of the ribbon stack pass by the ridge at intermittent locations along the length of the jacket, and wherein interaction between the ridge and the ribbon stack facilitates coupling of the ribbon stack to the jacket.

Abstract: 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.

Abstract: 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.

Abstract: 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. The jacket includes preferential tear portions disposed between a respective strength member and the medial portion, for separating the strength members from the medial portion.

Abstract: A fiber optic cable includes a jacket forming a cavity therein, a stack of fiber optic ribbons located in the cavity, and a strength member embedded in the jacket. The jacket forms a ridge extending into the cavity lengthwise along the fiber optic cable. The ribbon stack is spiraled through the cavity such that corners of the ribbon stack pass by the ridge at intermittent locations along the length of the cable, where interactions between the ridge and the corners of the ribbon stack facilitate coupling of the ribbon stack to the jacket.

Abstract: A sub-assembly of a fiber optic cable, the sub-assembly includes a central strength member, core elements wound about the central strength member in a stranded configuration, wherein the core elements comprise buffer tubes, filler rods, secondary strength members, and/or conductive wires, and a binder film overlaying the stranded core elements, the binder film comprising a polymeric material having a Young's modulus of 3 gigapascals or less such that the binder film constrains the core elements.

Abstract: Cables jacket are formed by extruding discontinuities in a main cable jacket portion. The discontinuities 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, and can be introduced into the extrudate material flow used to form the main portion through ports in the extrusion head. 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.

Abstract: Cables jacket are formed by extruding discontinuities in a main cable jacket portion. The discontinuities allow the jacket to be torn to provide access to the cable core. The armor cables have an armor layer with armor access features arranged to work in combination with the discontinuities in the cable jacket to facilitate access to the cable core.

Abstract: Cables are constructed with embedded 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 polymer material coextruded in the cable jacket.

Abstract: Cables have dielectric armors with armor profiles that provide additional crush and impact resistance for the optical fibers and/or fiber optic assembly therein, while retaining flexibility to aid during installation. The armored cables recover substantially from deformation caused by crush loads.

Abstract: A fiber optic cable includes a core, armor surrounding the core, and a jacket surrounding the armor. The core includes tubes, each tube having a passage defined therein, optical fibers positioned in the passages, and a binder sleeve defining an exterior of the core. Portions of the binder sleeve are directly bonded to the armor, while other portions are not. Spacing between the armor and the core, as well as the bond between the armor and binder sleeve, facilitate tubing-off of an end section of the cable to include removal of the binder sleeve.

Abstract: An optical communication cable subassembly includes a cable core having optical fibers each comprising a core surrounded by a cladding, buffer tubes surrounding subsets of the optical fibers, and a binder film surrounding the buffer tubes. Armor surrounds the cable core, the binder film is bonded to an interior of the armor, and water-absorbing powder particles are provided on an interior surface of the binder film.

Abstract: 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.
