ABSTRACT:
A separate mount type optical coupler having composite functions in which, of a plurality of optical fibers (f.sub.1, f.sub.2 and f.sub.3) arranged side by side, adjacent fibers are fusion-welded and extended at a plurality of places so as to provide, for example, a light mixing/branch-filtering function and a branching/coupling function individually, and the fusion-welded and extended portions are separately fixedly mounted, whereby connection portions and excessive length processing are eliminated.
