ABSTRACT:
The end portions of a plurality of optical optical fibers are stripped; the coated portions of the fibers constituting pigtails. The stripped portion of one of the fibers is fused to an uncoated fiber section having a diameter that is larger than that of the stripped fiber end portions. A fiber optic coupler preform is made by surrounding the uncoated fiber section with the stripped portions of the remaining fibers to form a close-packed fiber array. At least a portion of the overlapping region of the uncoated fiber section and the stripped end portions is heated and drawn to induce the coupling of optical signals between the uncoated fiber section and the stripped portions.
