ABSTRACT:
This coupling means comprises a sleeve containing a bore in which is located a bundle of optical fibers, at least some of which are of compression-deformable material. The input ends of the fibers, which receive light from a light source, are located in a predetermined plane. The bore tapers from a relatively large diameter at a location in a second plane spaced from said predetermined plane to a relatively small diameter at said predetermined plane. The tapered bore is of such a size that the optical fibers therein are laterally compressed and the compression-deformable fibers are so deformed in transverse cross-section relative to their normal cross-sections that the fibers more completely fill the bore in its relatively small diameter region than in said second plane.
