Abstract
A tube slitter for removing the outer metallic cladding of an optical power ground wire includes a channel guide for directing the movement of the tube slitter along the length of the ground wire. The ground wire includes an inner grooved spacer that engages with the channel guide. A cutting wheel is formed within the tube slitter and is free to rotate as the slitter is pulled along the length of the ground wire. The cutting wheel is positioned to provide a depth of cut sufficient to slit open the cladding tube without damaging the underlying optical fibers.
Claims4
A tool for slitting and removing a cladding layer included in an optical power ground wire, the ground wire including an inner grooved spacer with optical fibers disposed along the grooves, said tool comprising
- a central cylindrical member disposed to surround said ground wire;
- a guide channel disposed at a first end of said tool beyond the central cylindrical member, said guide channel exhibiting a profile sized to fit around and capture a first groove of an optical power ground wire inner spacer, preventing radial movement of the tool with respect to said optical power ground wire;
- a handle for moving said tool along the length of the optical power ground wire;
- and
- at least one cutting wheel disposed between the handle and the guide channel, said at least one cutting wheel held in a manner such that said at least one cutting wheel is free to rotate and engage an optical power ground wire cladding layer so as to slit open said optical power ground wire cladding layer without cutting any optical fibers disposed beneath said optical power ground wire cladding layer.
