  • Glass sleeve fiber joining
    Patent number: 4078910
    Abstract: A permanent butt joint between optical fibers is made by inserting the bare fiber ends into the opposite ends of a slightly oversized bore in a sleeve of glass of lower melting point than the fibers. The central region of the sleeve is collapsed by softening. By this collapse, the butted fibers are brought into alignment. The joint may be protected with a length of heat shrink tubing fitted over the sleeve.
