Abstract
There is provided a method of manufacturing an optical connector, including: preparing a multi-core optical fiber including a glass fiber and a resin coating that covers the glass fiber; inserting the glass fiber exposed from the resin coating into the ferrule such that the glass fiber protrudes from an end surface of a ferrule by a length A; rotating and aligning the multi-core optical fiber with respect to the ferrule; fixing the multi-core optical fiber to the ferrule; and so as to scrap off a tip end of the ferrule by a length. A deviation angle in the circumferential direction between a first initial end surface of the one end of the prepared glass fiber and a cross section of the glass fiber separated from the initial end surface by a length A+B mm is equal to or less than 0.9°.
