ABSTRACT:
A splicing apparatus includes a chamber which serves as a locus of functional convergence for a fiber holder, a laser and a viewing system. This arrangement permits several procedural steps, including a splicing operation and a hermetic coating operation to be performed using a single thermal laser heat source and without significantly disturbing the fibers between operations. The apparatus and the method practiced yield a splice which is comparable in optical, mechanical and physical properties to the original cable. Thus, for example, hermetically sealed optical fiber cables suitable for oil-well logging can be manufactured by splicing together the more limited cable lengths available using drawing techniques alone.
