Abstract
An optical connector includes a ferrule, a first optical fiber retained in the ferrule, a clamp section including an insertion section where a second optical fiber is inserted, a solid index-matching material disposed on an end face of the first optical fiber on an insertion section side, and a projecting portion on the end face of the first optical fiber and that projects more toward the insertion section side than a central region of the end face. The clamp section centers and fixes the first optical fiber and the second optical fiber.
Claims11
An optical connector comprising:
- a ferrule;
- a first optical fiber retained in the ferrule;
- a clamp section including an insertion section where a second optical fiber is inserted;
- a solid index-matching material disposed on an end face of the first optical fiber on an insertion section side;
- and
- a projecting portion on the end face of the first optical fiber and that projects more toward the insertion section side than a central region of the end face, wherein
- the clamp section centers and fixes the first optical fiber and the second optical fiber,
- the clamp section further includes a base member including a centering groove, and a lid member that presses the first optical fiber and the second optical fiber toward the centering groove,
- an end of the first optical fiber is disposed in the centering groove, and
- the projecting portion is disposed at a lid member side as viewed from the central region.

An optical fiber connection device comprising:
- a base member including a centering groove that centers an end face of a first optical fiber and an end face of a second optical fiber;
- a lid member that presses the first optical fiber and the second optical fiber toward the centering groove;
- an insertion section where the second optical fiber is inserted;
- a solid index-matching material disposed on an end face of the first optical fiber on the insertion section side;
- and
- a projecting portion on the end face of the first optical fiber and that projects more toward the insertion section side than a central region of the end face, wherein
- an end of the first optical fiber is disposed in the centering groove, and
- the projecting portion is disposed at a lid member side as viewed from the central region.

An optical connector manufacturing method comprising:
- providing an unassembled optical connector that includes a ferrule, a first optical fiber retained in the ferrule, and a clamp section including an insertion section, a base member, and a lid member;
- inserting a second optical fiber into the clamp section through the insertion section;
- abutting an end face of the first optical fiber, disposed in a centering groove of the base member, and an end face of the second optical fiber against each other;
- and
- fixing the first optical fiber and the second optical fiber using the clamp section, by pressing the first optical fiber and the second optical fiber toward the centering groove with the lid member, after the first optical fiber and the second optical fiber have been abutted against each other, wherein
- a solid index-matching material is disposed on an end face of the first optical fiber on an insertion section side,
- a projecting portion on the end face of the first optical fiber projects more toward the insertion section side than a central region of the end face, and
- the projecting portion is disposed at a lid member side as viewed from the central region.
5 more elements
An optical fiber connection method comprising:
- abutting an end face of a first optical fiber, disposed in a centering groove of a base member of a clamp section including the base member and a lid member, and an end face of a second optical fiber against each other, wherein the second optical fiber is inserted into the clamp section through an insertion section of the clamp section;
- and
- fixing the first optical fiber and the second optical fiber using the clamp section, by pressing the first optical fiber and the second optical fiber toward the centering groove with the lid member, after the first optical fiber and the second optical fiber have been abutted against each other, wherein
- a solid index-matching material is disposed on an end face of the first optical fiber on an insertion section side,
- a projecting portion formed on the end face of the first optical fiber projects more toward the insertion section side than a central region of the end face, and
- the projecting portion is disposed at a lid member side as viewed from the central region.
