摘要： An optical communication cable is provided having a cable body with an inner surface defining a passage within the cable body and a plurality of core elements within the passage. A film surrounds the plurality of core elements, wherein the film directs a radial force inward onto the plurality of core elements to restrain and hold the plurality of core elements in place.

摘要： A fiber optic cable includes a cable core of core elements and a protective sheath surrounding the core elements, an armor surrounding the cable core, the armor comprising a single overlap portion when the fiber optic cable is viewed in cross-section, and a jacket surrounding the armor, the jacket having at least two longitudinal discontinuities extruded therein. A method of accessing the cable core without the use of ripcords includes removing a portion of the armor in an access section by pulling the armor away from the cable core so that an overlap portion separates around the cable core as it is being pulled past the cable core. A protective sheath protects the core elements as the armor is being pulled around the cable core.

摘要： A recirculating powder applicator includes an applicator body having an inlet on an upstream surface and an outlet on a downstream surface, wherein the inlet and outlet define a passage that extends transversely through the thickness of the applicator body, a powder conduit, an air inlet, an exhaust aperture located on one of the upstream or downstream surfaces, and a circulation chamber located on the interior of the applicator body. The powder conduit and air inlet are in fluid communication with the passage and the passage is in fluid communication with the circulation chamber. A method of applying powder to a substrate during a continuous process includes using a recirculating powder applicator.

摘要： A fiber optic cable includes core elements wound in a pattern of stranding, the core elements comprising tubes surrounding optical fibers. The fiber optic cable further includes an binder film surrounding the stranded core elements. The binder film is continuous peripherally around the core elements, forming a continuous closed loop when viewed in cross-section, and continuous lengthwise along a length of the cable that is at least a meter. Further, the binder film is in radial tension and opposes outwardly transverse deflection of the core elements.

摘要： A fiber optic cable includes an optical fiber, strength components disposed on opposite sides of the optical fiber, and a polymeric cable jacket. The optical fiber includes a glass core, a glass cladding, and a polymer coating. The cable jacket surrounds the optical fiber and the strength components. Further, the cable jacket is tightly drawn onto the optical fiber, where excess fiber length of the optical fiber is such that positive strain is present in the optical fiber at room temperature (25° C.).

摘要： A flame-retardant fiber optic cable includes core elements, a film surrounding the core elements, and a jacket surrounding the film. The core elements include one or more optical fibers and at least one tube surrounding the one or more optical fibers. The material composition of the film differs from the jacket and the film is relatively thin.
