摘要： A fiber optic cable includes a messenger section having at least one strength member, a carrier section having at least one optical fiber therein, and a common jacket that forms a common jacket. In one embodiment, the carrier jacket has a preferential tear portion adjacent to the at least one optical fiber with a substantially continuous outer surface in the carrier jacket adjacent to the preferential tear portion. The preferential tear portion may be defined by at least one of: at least one internal void, at least one weld line, and at least one wing extending from a tape disposed about the one or more optical fibers. Various alternatives are possible. For example, the carrier jacket may also or alternatively include at least one gripping area extending for enhancing the gripping of the carrier section when pulling apart the carrier section and messenger section.

摘要： A fiber optic cable assembly includes a fiber optic cable, a tether, and an overmold. The fiber optic cable includes an optical fiber, a strength member, and a jacket, where the jacket includes an interior portion contacting the strength member and an exterior portion adjoining the interior portion. The interior and exterior portions of the jacket both include polyethylene, and the exterior portion further includes an additive that is not in the interior portion. The tether is coupled to the fiber optic cable at an attachment point. The optical fiber or another optical fiber spliced to the optical fiber, diverges from the fiber optic cable via the tether. The overmold encloses the attachment point and is attached directly to a discrete section of the exterior portion of the jacket proximate to the attachment point. The additive facilitates bonding of the overmold to the discrete section.

摘要： Fiber optic articles, assemblies, and cables preserve optical performance by using optical waveguides having a core, a cladding, and a coating system according to the present invention. Moreover, the optical articles, assemblies, and cables of the present invention may achieve performance levels that were previously unattainable, for instance, the present invention contemplates acceptable optical performance for wavelengths such as 1625 nm and higher. Additionally, articles, assemblies, and/or cables of the present invention advantageously preserve optical performance, i.e., have relatively low delta attenuation, when subjected to manufacturing processes and/or environmental conditions such as temperature cycling. In other words, the articles, assemblies, and cables can withstand increased stress/strain before having significant attenuation.

摘要： A tight buffered optical fiber having a protective layer generally surrounding the optical fiber, a release layer at least partially bonding to and generally surrounding the protective layer and a buffer layer generally surrounding and being strippable from the release layer. The release layer including an acrylate with oligomers, monomers and a reactive release substance distributed with a matrix. The reactive release substance may include a silicone selected from the group including methyl and phenyl silicones. The matrix may be mechanically or chemically bonded to the protective layer so that stripping the buffer layer does not remove the release layer.

摘要： 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 moveably 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.
