Abstract
An interconnect system for ribbon-joined optical fibers includes two connectors (1, 2) integrally attached to the ends of respective optical fiber ribbons (3, 4), in which each connector (1, 2) consists of a pair of coupled metal plates (5) rigidly fastened to each other, between which two or more optical fibers (7) belonging to a ribbon (3, 4) made of parallel optical fibers as well as alignment plugs (10) are clamped. At least a plate (5) in each connector (1, 2) includes an element made of metallic material in which several housing grooves (6, 9) for the optical fibers (7) of the ribbon (3, 4) and for the alignment plugs (10) are formed by cold plastic deformation using the same punch for all the plates belonging to one series. The method of accomplishing the invention includes making several grooved plates (5) by plastic deformation using a single punch; coupling a grooved plate (5) to a second plate and interposing therebetween the optical fibers (7) which are part of an optical fiber ribbon (3, 4) and on a length of which the common covering has been removed, partially housing the fibers (7) in the respective grooves (6); inserting a metered amount of hardening adhesive between the plates (5) clamped against the fibers (7); grinding the end surface of the plates (5) from which the fibers (7) issue; and introducing at least an alignment plug (10) into a respective groove (9).
