METHOD OF PRODUCTION OF OPTICAL CONNECTOR

摘要

A method of production of an optical connector which can adjust a protruding length of a bare optical fiber (7) from a connection end face (3) of a ferrule. At a step (a), an optical fiber core wire (5) is inserted through an optical fiber connection hole (4) of the ferrule (1), and the bare optical fiber (7) and the ferrule (1) are heated at a first curing temperature to cure a thermosetting adhesive (11). At the next step (b), the connection end face (3) is polished to make an end face flush with the distal end face of the bare optical fiber (7). At the next step (c), the thermosetting adhesive (11) is again heated and cured at a temperature higher than the first curing temperature and the distal end of the bare optical fiber (7) is allowed to protrude from the connection end face (3) by utilizing the pistoning phenomenon due to this re-heating curing. This protruding distance is adjusted by controlling either one, or both, of the re-curing temperature and the retention time at that temperature.
