摘要:
For removal of the protective coating (51) of cables, in particular optical 12-fiber ribbons and other optical multifiber ribbons, a tool divided into several segments (53) is used. Each of the segments have a pair of blades (55) comprising opposed edges and they are displaceable in relation to each other only a predetermined distance. When the tool is applied to a cable and a force is applied to the end thereof in the longitudinal direction of the cable, the protective jacket will be removed in stages, but still in a single operation, so that first a short subsection at the end of the cable is pulled away through some distance and then a short subsection further away from the end of the cable, etc. The force required when using this method is relatively small and the protective jacket can therefore be removed in unbroken pieces without being scraped off or made to particles.

The present invention provides a separating tool for separating a multi-core ribbon fiber (1) obtained by arranging a plurality of optical fibers (1a) in a plane and integrating the fibers with a common coating (1b) into single-core optical fibers, and includes a fiber accommodating means for accommodating the multi-core ribbon fiber (1) in an accommodating area (2), a fiber holding means for holding the multi-core ribbon fiber (1) in the accommodating area (2), a scratching means (3) for forming a scratch on a surface of a common coating (1b) of the multi-core ribbon fiber (1) held by the fiber holding means, an arrangement defining means (4) for changing an pitch position of the scratching means (3), and a shearing force applying means (5) for applying a shearing force to the multi-core ribbon fiber (1) along the scratch formed by the scratching means (3).

摘要:
Die Vorrichtung dient zur Oberflächenbehandlung von beschichteten Elementen (3; 30; 300), insbesondere von Kabeln, deren Beschichtung (31, 310) mittels wenigstens zwei Laserdioden (1a, ..., 1h) abgetragen oder aufgetrennt wird. Die Laserdioden (1a, ..., 1h) sind auf einem Montagekörper (2; 5; 200) montiert und derart ausgerichtet oder können derart ausgerichtet und bewegt werden, dass die Beschichtung (31, 310) eines Elementes (3; 300) an einer vorgesehenen Stelle abgetragen oder aufgetrennt wird. Vorzugsweise wird ein hohlzylindrischer Montagekörper (2; 5; 200) verwendet, der mit einer ungeraden Anzahl von Laserdioden (1a, ..., 1h) bestückt wird, die gleichmässig über den Montagekörper (2; 5; 200) verteilt sind.
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 (70), and a moveable shearing device (50), the moveable shearing device (50) is operative to move relative to the stationary shearing device (70) during a shearing stroke. Optical fiber ribbon support elements (42), with optical fiber ribbon receiving slots (46) being defined therebetween, are adjacent shearing devices (50,70). Moveable shearing device (50) is moveably located between optical fiber ribbon support elements (42) and includes moveable sub-slots (51,52). When a cover member (60) of tool (10) is in a closed position, stationary sub-slots (71,72) of stationary shearing device (70) are aligned with moveable sub-slots (51,52) to define shearing slots (51,71;52,72). Shearing slots (51,71;52,72) 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). At least one shearing device (50,70) is monolithically formed of a single piece of material.
摘要:
A method of removing matrix from a fiber optic cable includes the steps of providing a foil layer (18), placing a sheet of wiping material (16) atop the foil layer, positioning a portion of fiber optic cable (10) coated with a matrix (14) on the sheet of wiping material, folding the foil layer and sheet of wiping material together, spraying solvent (26) into the folded wiping material, and confining the fiber optic cable inside the folded sheet of wiping material within the folded foil layer until the matrix dissolves. A durable folder may be used with the method to provide a portable work station and secure both the sheets of wiping material and the foil layer. A portable case (20) containing materials necessary for practicing the method of the present invention also is disclosed.
