20120237172OPTICAL-FIBER MECHANICAL SPLICER USING HEAT-SHRINK FERRULE - Apparatus and methodology for providing a mechanical-only splice between two optical glass fibers. No fusion splicing is involved. A heat-shrinkable plastic ferrule containing an aperture extending from one end of the ferrule to the other accepts a different cleaved and cleaned optical fiber into each of its two ends, the fibers meeting at or near the middle of the ferrule in a parallel or coplanar manner forming a splice junction.
