Abstract: An improved fiber optic cable assembly is provided which has made integral therewith a strength member that may be gripped or rigorously pulled to facilitate the installation of the fiber optic cable assembly in a structure.

Abstract: A fiber optic illumination cable comprises two fiber optic illumination bundles and a resilient, flexible, light-absorbent material which separates the two bundles. The first bundle has a generally round cross-section, and is covered with a resilient, flexible light-absorbent material. The second illumination bundle is disposed about and contiguous with the resilient, flexible, light-absorbent material layer which surrounds the first bundle. The second illumination bundle is cabled to form an annular ring, with a generally circular cross-section, which gives the final cable an even, full, round cross-section, with a low cross-sectional area. The two cabled illumination bundles are covered with a layer of a resilient, flexible material, which does not need to be light-absorbent, and a protective polymer jacket.

Abstract: An asymmetrically shaped signal polarization maintaining optical waveguide including an asymmetrically shaped optical fiber surrounded by glass cladding, hard polymer coating, soft porous polymer buffering layer, porous polymer laminate inner layer, polyester laminate outer layer bearing tabs oriented to an axis of asymmetry of the optical fiber, braid fiber sheath, and outer jacket, the observable tab orientation on the outside of the cable providing location means of the axis of asymmetry of the optical fiber.

Abstract: A polymer-insulated crush-resistant high-strength optical waveguide fiber cable buffered by a braided layer of porous polytetrafluoroethylene fibers to provide strength, a low thermal expansion coefficient buffer, and strong environmental protection.

Abstract: Expanded polytetrafluoroethylene-buffered, polyester insulated, braided aramid sheath or aramid cloth strengthened, fire retardant jacketed optical fiber ribbon cables having precisely spaced optical fibers and processes for their manufacture.

Abstract: An isolated core cable for isolating a crush-sensitive core contained therein against a harsh environment, such as a fiber optic cable, a coaxial electric cable, a hydraulic line, or a pneumatic gas line, the cores therein being supported by a helically slit hard polymer tube inside a preferably braided fiber strength member. A resilient material may be wrapped around the cores inside the slit tube to further protect the cores from elongation and bending stresses.

Abstract: A flat electrical power-carrying pod for inclusion as a component in a ribbon cable comprising a multiplicity of parallel wires insulated as a unit by polytetrafluoroethylene and having on each side of the plane of wires a layer of hard cut-through resistant film not contacting the other hard polymer layer. Polyimide is the preferred hard polymer.

Abstract: A polymer-insulated glass optical waveguide fiber cable is buffered by an adhesively bound soft porous polytetrafluoroethylene taper layer to minimize stress on the glass fiber core and provide a low thermal expansion coefficient buffer and strong environmental protection.
