    摘要: The invention is directed to a method of manufacturing an optical connector according to which it is possible to adjust a projection length a bare optical fiber (7) projects from a connection end surface (3) of a ferrule (1). At a step (a), an optical fiber cored line (5) is inserted through and attached to an optical fiber insertion hole (4) of the ferrule (1), and the bare optical fiber (7) and the ferrule (1) are bonded to each other by hardening a heat-hardening adhesive (11) at a first hardening temperature. Next, at a step (b), the connection end surface (3) is ground so that the connection end surface (3) becomes flat and flush with a tip surface of the bare optical fiber (7). Following this, at a step (c), the heat-hardening adhesive (11) is heated again to be hardened at a temperature which is higher than the first hardening temperature, so that a tip of the bare optical fiber (7), causing pistoning due to the reheat hardening, projects from the connection end surface (3). The quantity of the projection is adjusted by controlling one or both of the rehardening temperature and a holding time at the rehardening temperature.

    摘要: A ferrule for an optical connector wherein the work efficiency of the manufacture is increased by reducing the time necessary for grinding and the reliability of the connection of the optical connectors is improved. A front end surface (2) of a ferrule (1) comprises a flat surface (16) vertical to the central axes of optical fiber insertion holes (3) and a slanting surface (15). A step (17) is provided at the upper end of a slanting surface (15) and the flat surface (16) protrudes frontward by the step (17) with respect to the slanting surface (15). The optical fiber insertion holes (3) open at the slanting surface (16) and pin engagement holes (4) are provided on both sides of the optical fiber insertion holes (3).
