    摘要： The access tool includes a housing (10) and a block (20) disposed within the housing. The housing has side walls (12) connected by a bottom wall (15) thereby forming a channel (11). The block is disposed within the channel so as to be slidable along the longitudinal axis of the housing, as well as to be movable toward and away from the bottom wall so that the tool may be used on a wide range of optical conductor sizes. The block includes at least one projection (28) which is disposed in at least one groove (13) in the housing so as to connect the block and housing in a simple manner.
    To separate a sheath from an optical conductor, the optical conductor is placed within the channel, and then the block is moved toward the bottom wall to squeeze the optical conductor. The optical conductor is then pulled relative to the access tool thereby separating the sheath from the fibers in the optical conductor.

    摘要： La présente invention concerne un câble plat pour véhiculer de la puissance électrique et/ou des informations sous la forme de signaux électriques ou optiques.
    Ce câble (10) comporte cinq fils électriques (11, 12, 13, 14 et 15) disposés en nappe et enrobés dans une couche de matière synthétique (16) isolante ou protectrice. Il comporte un renflement ou une protubérance longitudinale (17) qui s'étend tout au long du câble. Cette protubérance (17) comporte une cavité (18) axiale continue qui peut être creuse ou remplie d'un matériau de bourrage friable.
    Par des entailles axiales faites dans la protubérance longitudinale, il devient aisé "d'éplucher" la couche isolante et de dénuder les fils électriques.

    摘要： Midspan access to selected optical fibers which are encapsulated in an optical ribbon or tube is achieved by placing the desired span of the encapsulated fibers to be accessed between opposing abrasive layers and controllably urging at least one of the abrasive layers in the direction of the opposing abrasive layer to cause both abrasive layers to contact the encapsulant which covers the fibers. The amount of force applied to the at least one abrasive layer is limited by the structure of a resilient element which is coupled to the abrasive surface. Stress concentrators are created in the encapsulant and the encapsulant is removed from the span portion by relative movement of the encapsulated fibers and the abrasive layers. A minimum separation distance between the opposing abrasive layers can be defined, according to the thickness of the specific encapsulated fiber medium undergoing fiber separation, to avoid contact between the abrasive surfaces and the fibers within the medium. Access to the individual fibers is provided after the stress concentrators are formed in the encapsulant or encapsulant in the desired span portion has been substantially removed.

    摘要： An optical fiber ribbon includes a plurality of coated, substantially coplanar optical fibers (2) and a ribbon matrix material (4) which maintains the pluratily of coated optical fibers (2) in substantially coplanar alignment. Each of the optical fibers (2) includes a glass core (6), a cladding layer (8) surrounding and adjacent to the glass core (6), and a primary polymeric coating material (10), preferably containing a silicone, surrrounding and adjacent to the cladding layer (8). The primary polymeric coating material (10) adheres to the cladding layer (8) to form a cladding layer-primary polymeric coating interface. Upon application of a longitudinal stripping force at the cladding layer-primary polymeric coating interface, the ribbon matrix material (4) and the primary polymeric coating material (10) are substantially removed from the cladding layer (8).

    摘要： A one-part, cured, radiation-curable liquid matrix composition for affixing coated and inked optical fibers in a ribbon configuration which is peelable from the coated and inked fibers without damage to the integrity of itself or the fibers is disclosed. The composition comprises an aliphatic urethane acrylate oligomer; a reactive monomer having one or more acrylate or methacrylate moieties; a release agent; and an optional photoinitiator. Also disclosed are an optical fiber ribbon array prepared therefrom; a process for removing such matrix composition from inked and coated fibers; a process for preparing such ribbon array; and a radiation-curable coating composition generally applicable for coating a substrate.
