ABSTRACT Method and apparatus for fabricating optical fibers For continuous manufacture of optical fibers, bars of homogeneous silica-base material are welded in end to end relation. A silica cladding containing a proportion of index varying dopant which varies as the diameter of the cladding increases is progress- ively applied on a bar at a time to form successive preforms and the welded preforms are drawn out into fibers.
