ABSTRACT:
A branching method for multi-fiber fiberoptic cables which comprises stripping off the jacket of a multi-fiber cable at the branching point, stripping the kevlar from the cable slightly beyond the branching point, folding back the kevlar over the jacket and holding the kevlar in place with heat shrink tubing leaving a portion of kevlar exposed about the end of the jacket with the individual buffered fibers extending beyond that point. Thereafter, a section of high grade heat resistant teflon tubing is slid onto each buffered fiber until a portion of the section of teflon tubing extends into the interior of said cable. Thereafter, a sheathing is prepared for each individual buffered fiber. The jacket of each sheathing is stripped slightly beyond its end point, the kevlar is folded back over the jacket and the kevlar is held in place with heat shrink tubing leaving a portion of kevlar exposed about the end of the jacket. A prepared sheathing is then slid onto each individual buffered fiber until a portion of the section of teflon tubing extends into the interior of said sheathing. Thereafter, the entire cable and sheath assembly about the branching point is placed in an injection mold cavity and a PVC mold is formed about the branching point. Each of the exposed portions of kevlar adheres to the PVC mold, thereby maintaining the integrity of the strength member. The sections of high grade heat resistant teflon tubing protect the buffered fibers from the stresses of the injection mold, thereby maintaining the integrity and freedom of the fibers.
