Abstract
To enable sequential fusion splicing of the optical fibers of two lengths of optical fiber ribbon, the fusion splicer has, on each side of the fusion station, means for arranging the exposed end portions of the optical fibers of each ribbon, over a limited length between the position at which they are lightly clamped and the cut back end of the ribbon, to follow a curved path whose centers of curvature lie on a line extending transversely of the ribbon. Preferably, one of these means is an externally screw threaded rod which extends under and transversely of the optical fibers of one of the ribbons and in the grooves of which the optical fibers are arranged to lie. By unscrewing the rod, each lightly clamped optical fiber in turn drops from the rod and straightens so that its end to be fusion spliced protrudes beyond the ends of the other optical fibers of the ribbon. Fusion splicing of the pair of aligned optical fibers is then effected. The risk that any other pair of optical fibers of the ribbons will be prematurely partially fused together during fusion splicing of a pair of optical fibers is substantially reduced.
