Abstract
An optical receptacle includes: a first optical fiber; a second optical fiber connected to the first optical fiber by fusion splice; a ferrule including a fiber hole that holds an end of the first optical fiber; and a housing portion that houses therein: the ferrule, the first optical fiber, and a first portion of the second optical fiber. A fusion splice portion between the first optical fiber and the second optical fiber is disposed outside of the ferrule and within the housing portion.
Claims4
An optical receptacle comprising:
- a first optical fiber having a first mode field diameter;
- a second optical fiber having a second mode field diameter that is different from the first mode field diameter;
- a ferrule comprising a fiber hole that holds an end of the first optical fiber;
- and
- a housing portion that comprises:
- a ferrule flange that directly holds the ferrule,
- and
- a receptacle flange comprising an insertion hole into which an optical connector plug is inserted, wherein
- the first and second optical fibers are connected by fusion splice at a fusion splice portion disposed outside of the ferrule and within the ferrule flange that directly holds the ferrule, and
- a mode field diameter of the fusion splice portion gradually varies from the second mode field diameter to the first mode field diameter in a direction from the second optical fiber to the first optical fiber.

A method of manufacturing an optical receptacle, the method comprising:
- connecting a first optical fiber to a second optical fiber by fusion splice at a fusion splice portion, wherein the first optical fiber has a first mode field diameter and the second optical fiber has a second mode field diameter that is different from the first mode field diameter, and a mode field diameter of a fusion splice portion gradually varies from the second mode field diameter to the first mode field diameter in a direction from the second optical fiber to the first optical fiber;
- inserting an end of the first optical fiber into a fiber hole of a ferrule such that the fusion splice portion is disposed outside of the ferrule and within a ferrule flange that directly holds the ferrule;
- attaching a receptacle flange comprising an insertion hole to a ferrule assembly comprising the ferrule and the ferrule flange;
- and
- inserting an optical connector plug into the insertion hole.
