ABSTRACT:
Blemish quality of fused fiber optics faceplates, tapers, image inverters and other arrays of multifibers is improved by protecting outer fibers of the multifibers from excessive heating and/or contamination during their fabrication. A preform of a multiplicity of optical fibers is covered with a protective layer of removable material while being fused into a building block. The protective layer is removed from each of the building blocks and the blocks are subsequently assembled into a juxtaposition and fused into a fiber optic array. Multifibers so fabricated and used as component building blocks for the arrays uniquely minimize traditional "chicken wire" blemishing.
