  • Patent number: 11280977
    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.

  • Patent number: 10845558
    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).

  • 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.
