Abstract: PROBLEM TO BE SOLVED: To adequately discriminate many optical ribbons and distinguish the optical ribbons from each other by the inspection of only the ribbons without depending upon position information by string optical fiber ribbons marked in binary code. SOLUTION: An optical fiber ribbon 12 has ribbon subunits 21 and 22 which can be mutually separated and they have different binary codes on them. Binary codes in a rectangular shape are preferable while the use of Arabic numbers and English letters is avoided. The ribbon subunit 21 is given the binary code 20 and the ribbon subunit 22 is given the binary code 20. The ribbon subunit 21 houses plural optical fibers 26 and the ribbon subunit 22 houses plural optical fibers 14. The optical fibers 14 and 26 have surfaces in mutually different colors so that they can be distinguished from each other. The optical fibers should be in light colors so that the read of the ink codes is not impeded.

Abstract: Los listones y subunidades de liston en cables de fibra optica pueden distinguirse uno del otro imprimiendo informacion binaria o codificada en barras legible por máquina en forma periodica a lo largo de la longitud de los listones o subunidades de liston. Las repeticiones de codificacion pueden colocarse sobre los listones mediante una impresora de chorro de tinta.

Abstract: In a ribbon type fiber optic cable there is disposed a stack of fiber optic ribbons, each composed of a set of individually coated optical fibers in a planar relationship to one another with the set of coated optical fibers also coated by a common coating of ultraviolet light cured material. The coefficient of friction between adjacent ribbons in a stack is equal to or less than 0.70.

Abstract: A light waveguide cable contains a layer of U-shaped carriers around a central core. Each U-shaped carrier contains a light waveguide fiber, bundle, ribbon, or ribbon stack. Carrier legs have a predetermined hinge line at a distance from the carrier base greater than the thickness of the light waveguide fiber, bundle, ribbon or ribbon stack. The carrier legs may have a smaller thickness or a concavity at the hinge line.

Abstract: A ribbon separation tool (10) for separating optical fiber ribbons (C1,C2,C3) into subsets of optical fibers. Ribbon separation tool (10) includes a stationary shearing device (27), and a moveable shearing device (17), the moveable shearing device (17) is operative to move relative to the stationary shearing device (27) during a shearing stroke. Optical fiber ribbon support members (42), with optical fiber ribbon receiving slots (46) being defined therebetween, are adjacent shearing devices (17,27). Moveable shearing device (17) is moveable located between optical fiber ribbon support members (42) and includes moveable sub-slots (90a,90b,90c). When a cover member (26) of tool (10) is in a closed position, stationary sub-slots (92a,92b,92c) of stationary shearing device (27) are aligned with moveable sub-slots (90a,90b,90c) to define shearing slots (90a,92a;90b,92b;90c,92c). Shearing slots (90a,92a;90b,92b;90c,92c) are each sized to receive a respective optical fiber ribbon (C1,C2,C3), and each shearing slot straddles a shearing plane (M) defined between shearing devices (17,27). When tool (10) is actuated by pushing a pusher member (52) to an actuated position, ribbon (C1) will be separated into two 6-fiber subsets, ribbon (C2) will be separated into one 4-fiber and one 8-fiber subset, and ribbon (C3) will be separated into one 2-fiber subset and one 10-fiber subset. With pusher member (52) in the actuated position, optical fiber ribbons (C1,C2,C3) are then moved lengthwise whereby ribbons (C1,C2,C3) are separated lengthwise. Figures 4, 10, 14, and 15.

Abstract: Ribbons and ribbon subunits in optical fiber cables may be distinguished from one another by printing binary or machine-readable bar coded information inperiodic fashion along the length of the ribbons or ribbon subunits. The code repetitions may be placed on the ribbons by an ink jet printer.
