ABSTRACT:
A fiberoptic feedthrough fastener and method for forming same comprising sliding a first and second sections of heat shrink tubing up a fiberoptic cable beyond a fastening point. The jacket of the cable is then stripped off at the fastening point, the strength member is stripped off slightly beyond the fastening point, and the exposed strength member is folded back away from the buffered fibers. A section of protective tubing is slid over the exposed buffered fibers until it abuts the end of the jacket. The second section of heat shrink tubing is slid down the cable and the protective tubing. The exposed strength member is caught by the second section of heat shrink tubing and pulled over and about the protective tubing. The second section of heat shrink tubing is then secured about the protective tubing and exposed strength member. The first section of heat shrink tubing is slid down the cable and secured about the protective tubing and jacket forming a gap of exposed strength member between the two sections of heat shrink tubing. The entire assembly is placed in an injection mold cavity and a PVC mold is formed. The exposed aramid fibers in the strength member gap adhere to the PVC mold as it cools. The PVC mold is configured with a fastening path that conforms to an aperture in a housing. Two protrusions are included on the PVC mold that provide a grommet-like effect allowing the feedthrough fastener to be secured to the housing.
