Title:
METHOD FOR MANUFACTURING OPTICAL CONNECTOR FERRULE, OPTICAL CONNECTOR FERRULE, AND OPTICAL FIBER WITH CONNECTOR
Document Type and Number:
WIPO Patent Application WO/2018/168141
Kind Code:
A1
Abstract:
A method for manufacturing an optical connector ferrule includes a step of: filling a cavity of a mold with a resin, said cavity conforming to the shape of an optical connector ferrule; and curing the resin to form the optical connector ferrule. The optical connector ferrule includes: one end face and the other end face that face each other in a first direction; a pair of side surfaces that face each other in a second direction intersecting with the first direction; a front surface and a rear surface that face each other in a third direction intersecting with the first direction and the second direction; an inlet formed on the other end face to allow the collective insertion of a plurality of optical fibers along the first direction; and a window passing through from the front surface to the inlet. The distance between the center of a gate and the front surface in the third direction is shorter than the distance between the center of the gate and the rear surface in the same direction.
