  • Publication number: 20200132952
    Abstract: A fiber-optic cable having optical fibers that are arranged as a rollable ribbon. Water-swellable material (e.g., superabsorbent liquid, superabsorbent powder, superabsorbent adhesive, etc.) is applied directly to the rollable ribbon, thereby eliminating the need to incorporate conventional water-absorbing yarns, tapes, or other such similar materials. The rollable ribbon is surrounded by a tube, with a dielectric strength member positioned external to the tube and substantially parallel to the tube. A jacket, with a ripcord along a substantial length of the jacket, surrounds the tube. Also taught is a process for manufacturing a rollable-ribbon fiber-optic cable, in which a water-swellable material is applied directly to the rollable ribbon, thereby eliminating the need to incorporate conventional water-absorbing yarns, tapes, or other such similar materials.

  • Publication number: 20190391352
    Abstract: An optical fiber cable includes a rollable ribbon, reinforcing yarns, and a jacket. The Rollable ribbon has a plurality of optical fibers. Each optical fiber has a fiber strain greater than 0.6 percent under standard installation tensile load. The jacket encloses the rollable ribbon, the optical fibers and reinforcing yarns at a packing density greater than about 1.25 fibers per square millimeter. The combined effect of optical fibers having a fiber strain greater than 0.6 percent under standard installation tensile load and a small amount of reinforcing yarn provides the optical fiber cable with high proof strain, compact diameter, and high packing density.

  • Patent number: 10488613
    Abstract: An optical fiber distribution cable for servicing living units inside a MDU building, is formed by surrounding differently colored optical fibers with a jacket having a diameter of not more than about 3.5 mm. The jacket is opaque for hiding the colored fibers at least partially from view, thus reducing or eliminating any negative visual impact of the cable when installed. The colored cable fibers are arranged so that they are visible to an installer when only the cable jacket is cut open. Connection modules are mounted at corresponding living units, and a section of the cable is placed in each module. The jacket on a cable section in a given module is cut open, and a fiber assigned to the corresponding living unit is identified by color. The fiber is cut, and a length of the fiber is removed from the cable section and stored in the given module.

  • Patent number: 10310209
    Abstract: A tight-buffered optical fiber cable includes an improved method of accessing the coated optical fiber. The cable can include an optical fiber having a glass core and a cladding layer. One or more coating layers can be applied about the cladding layer. A buffer jacket material can be applied onto an outer surface of the outer coating layer as a buffer jacket outer layer. The buffer jacket outer layer can have distinctive features including a low tear strength, low elastic modulus, high elongation percentage, and low peeling force. This can allow a user of the optical fiber cable to separate at least a portion of the coated optical fiber from the buffer jacket outer layer by grasping a free end of the coated optical fiber and pulling it through the outer wall of the buffer jacket outer layer, thereby tearing through the outer wall of the buffer jacket outer layer.

  • Publication number: 20180224619
    Abstract: A high count optical fiber cable is formed of a number of sub-unit components stranded around a central tension member. Each sub-unit component is formed to include the total number of individual fibers required to populate a given equipment rack (e.g., 288 fibers, for example). The individual fibers are preferably provided using a plurality of rollable optical fiber ribbons (permitting the large number of individual fibers to be compacted into a relatively small space), with water blocking material included in each sub-unit component. The sub-unit components may be formed to include individual strength members (i.e., in the form of sub-unit cables), or as loose tubes with an outer strength member disposed to surround the sub-units. Each sub-unit component is specifically sized to match the fiber capacity of, for example, a full equipment rack, minimizing the number of physical cables required for high density applications (e.g., data centers).

  • Patent number: 9995899
    Abstract: An optical fiber distribution or breakout cable for serving multiple customer premises in a multi-dwelling unit (MDU) building. The cable contains a number of bend insensitive fibers each having a different colored coating for identification. A jacket of a flame-retardant polymer compound is extruded to surround the fibers. The jacket is sufficiently opaque to hide the color coated fibers at least partially from view, and the outer diameter of the jacket is not more than about 3.5 mm. A procedure for installing the cable through a hallway of a MDU building so as to lessen any negative visual impact of the installation on observers nearby is also disclosed.

  • Patent number: 9971114
    Abstract: A thread for tying a group of fibers in a fiber optic cable having an outer jacket to one another to form a fiber bundle. The thread includes a length of a binder thread, and an adhesion material coated on the binder thread so that (a) the binder thread adheres to the group of optical fibers about which the thread is tied to form the fiber bundle, and the binder thread remains adhered to the bundled fibers to restrain movement of the fibers when the outer jacket and cable elements other than the bundled fibers are removed. After the binder thread is tied about a fiber bundle, exposed surfaces of the adhesion material coated on the binder thread are treated so that the thread does not adhere to any cable elements in proximity to the thread, other than the fibers of the bundle about which the thread is tied.

  • Patent number: 9921381
    Abstract: An optical fiber cable comprising 200 micrometer (?m) optical fibers (fibers with an outer diameter of approximately 200 ?m) that are located within buffer tubes. This permits fiber packing densities of 3.8 fibers/mm2 or higher. The buffer tubes have wall thicknesses (tbuffer) between approximately 7.5 percent (7.5%) and approximately 30% of the buffer tube's outer diameter (ODbuffer), and a Young's modulus that is between approximately 750 mega-pascals (MPa) and 2,200 MPa, thereby providing the necessary structural integrity to resist kinking yet maintain flexibility.

  • Patent number: 9904025
    Abstract: Embodiments of the invention include a compression-resistant seismic optical fiber cable for repeated deployment. The seismic optical fiber cable includes a central core tube dimensioned to receive at least one bundle of optical fibers. The central core tube is dimensioned to allow the optical fibers in the at least one bundle of optical fibers to relax relative to the other optical fibers. The seismic optical fiber cable also includes at least one strength member layer surrounding the central core tube. The strength member layer provides flexibility and tensile strength to the seismic optical fiber cable. The seismic optical fiber cable also includes a jacket surrounding the strength member. The seismic optical fiber cable also includes at least one rigid fiber reinforced composite rod linearly applied within the jacket. The one linearly-applied rigid fiber reinforced composite rod provides compressive resistance for the seismic optical fiber cable.
