Patent number: 6401570Abstract: A cable stripping tool, for stripping insulation from a cable that includes a stripper cord, includes a cylindrical mandrel having first and second ends, with a cord end receptacle formed in at least one end. The receptacle is dimensioned to receive the exposed end of a stripper cord. In use, the exposed end of the stripper cord is inserted into the receptacle, and the mandrel is rotated about its longitudinal axis, thereby pulling the stripper cord through the insulation layer. When the desired point is reached along the length of the cable, the cord is cut. The coil of cord that becomes wrapped around the mandrel may be cut axially to remove the cord from the tool. In a preferred embodiment, the mandrel is formed as a hollow tubular extrusion, with a longitudinal slot along its entire length. Alternatively, the mandrel can be formed as a solid rod of material, with a longitudinal slot formed along its length.Type: GrantFiled: October 18, 2000Date of Patent: June 11, 2002Inventor: Frank D.

Patent number: 6397474Abstract: The present invention is a cable preparation tool which allows the preparation of a coaxial cable having a corrugated outer conductor to receive a connector in one step. The tool allows for the control of trim dimensions for each component of the cable without measuring. No matter whether the end of the cable before preparation is at the crest or valley of the outer conductor, the tool provides the correct trim dimensions for each component and stops cutting when these dimensions are reached. The cable preparation tool includes a main body having a cable receiving end, cable receiving area for stripping of the cable such that the crests and valleys are exposed, and a crest and valley locating system as part of the main body for locating the exposed crests and valleys of the corrugated conductor. The crest and valley locating system includes at least one valley locator unit extending into the cable receiving area and a spring that biases the valley locator unit into the cable receiving area.Type: GrantFiled: August 6, 1999Date of Patent: June 4, 2002Inventor: Roger M.

Patent number: 6273990Abstract: A method for mechanically stripping the protective coating from a silica or glass optical fiber using a polymeric or soft metal blade having a hardness less than that of the glass optical fiber but greater than the protective coating. The blade is preferably selected from a group of polymeric materials, or alternately a soft metal, which is selected or treated so as to not detrimentally oxidize in conventional operating environments. For a silica-containing optical fiber, the blade has a hardness of less than approximately 125 on the Knoop hardness scale, and preferably less than approximately 60 on the Knoop hardness scale. A method of inhibiting damage to the exposed region of the silica-containing optical fiber comprises applying a substance that forms a protective layer to provide a barrier to particulates and moisture, and which does not inhibit subsequent processing of the optical fiber, selected from a group of silane-containing compounds.Type: GrantFiled: June 30, 1999Date of Patent: August 14, 2001Assignee: Corning IncorporatedInventors: Dana C.

Patent number: 6192587Abstract: An auto-aligning ribbon splitter which can be used on any size optical fiber ribbon made by any manufacturer. The auto-aligning ribbon splitter centers an optical fiber ribbon over a first splitting edge so that it can be split into two sub-units each having an equal number of optical fibers therein. The auto-aligning ribbon splitter includes a bottom plate having a channel. The channel includes a first splitting edge. Two movable plates are disposed on the bottom plate so that they are parallel to, and are centered about, the first splitting edge. A mechanism, such as an adjustment rod, is connected to the movable plates to change their position relative to the first splitting edge, but maintain each plate at an equal distance from the first splitting edge. A second splitting edge, on a top body, may then be pressed against the centered ribbon to cause an initial split between two sub-units, as the top body pushes half of the ribbon into the channel on the bottom plate.Type: GrantFiled: December 1, 1999Date of Patent: February 27, 2001Assignee: AlcatelInventor: Justin Thompson
