Abstract: In order to couple an input end of an optical fiber to a light source designed to illuminate same with message signals, the light source--such as an LED--is mounted on a dielectric disk where it is surrounded by a flat ring confronting another ring with a stepped inner profile from which a cylindrical sleeve projects on the side opposite that disk. A capillary tube, closely fitting into the axial bore of the sleeve, is fitted around an extremity of the fiber stripped of its protective sheath so as to extend close to the source when the two rings are substantially coaxially juxtaposed; with the source energized, the light emitted at the opposite fiber end is measured to determine the correct alignment position in which the two rings are cemented to each other. The illuminated fiber end, rounded into spherical shape to act as a focusing lens, is then moved into the proper distance from the source by an axial shifting of the capillary tube in the sleeve whereupon the tube is cemented to the sleeve; the joints so formed are thereafter enshrouded in a protective cap.
