Abstract

Abstract An arrangement of optical fibers, apparatus and method for splicing same are described. The fiber arrangement comprises a plurality of fibers secured to a ribbon-like tape. The fiber segments to be spliced are mounted on the slidable holders of a splicer such that each of the fibers of one segment are aligned approximately coaxially with a fiber on the other segment. The individual fibers are then cut, as required; moved into position; more accurately aligned by mechanical means; and then bonded together by the application of either heat or a bonding material of suitable refractive index. In one arrangement, accurate alignment of the fibers is obtained by means of a grooved cover plate which is placed over the adjacent ends of the fibers and left in position until the bonding step is completed. Various means for mounting the fiber segments in the splicer and for strengthening the splice are disclosed. A modified splicer for liquid core fibers is also described.
