Abstract
An optical receptacle includes a fiber stub having an optical fiber with a core and cladding, a ferrule with a through-hole fixing the optical fiber, and a bonding agent fixing the optical fiber in the ferrule, and a holder holding the fiber stub. The optical fiber is disposed inside the through-hole over an entire region of the optical fiber, and includes a portion in which a core diameter and a fiber outer diameter decrease gradually toward an end surface of the ferrule on a side opposite to a side to be optically connected to a plug ferrule. The bonding agent is filled into a space between the optical fiber and an inner wall of the through-hole.
Claims8
An optical receptacle, comprising:
- a fiber stub including an optical fiber,
- a ferrule, and
- a bonding agent, the optical fiber including cladding and a core conducting light, the ferrule having a through-hole fixing the optical fiber, the bonding agent fixing the optical fiber in the ferrule;
- and
- a holder holding the fiber stub,
- the optical fiber including a first portion and a second portion, a core diameter and a fiber outer diameter in the first portion decreasing gradually toward an end surface of the ferrule on a side opposite to a side to be optically connected to a plug ferrule, the core diameter and the fiber outer diameter in the second portion being constant,
- the bonding agent being filled into a space between the optical fiber and an inner wall of the through-hole, the bonding agent existing in a configuration at an outer circumference of the first portion, and an entire region of the first portion and the second portion being disposed inside the through-hole;
- wherein the bonding agent is a high temperature-curing adhesive.
