Abstract

An optical fiber with a connector includes a first connector and a plurality of optical fibers attached to the first connector. The first connector includes: at least one fiber-shaped member; and a ferrule including a first end surface and a second end surface arranged in a first direction, and a holding portion holding the optical fibers and the fiber-shaped member. In the holding portion, a plurality of fiber insertion holes extending from the first end surface in the first direction is formed such that the optical fibers and the fiber-shaped member are insertable thereinto. One end of the optical fiber and one end of the fiber-shaped member are held by the holding portion in a state of being inserted into the fiber insertion hole. The optical fiber extends to the outside of the ferrule. The other end of the fiber-shaped member is located inside the ferrule.

First claim

1 . (canceled)

2 . The optical connection assembly according to claim 3 , wherein a fiber-shaped member includes a glass fiber.

3 . An optical connection assembly comprising:
a first connector; and a plurality of optical fibers attached to the first connector, wherein the first connector includes: at least one fiber-shaped member; and a ferrule including a first end surface and a second end surface arranged in a first direction, and a holding portion holding the optical fibers and a fiber-shaped member, in the holding portion, a plurality of fiber insertion holes extending from the first end surface in the first direction is formed such that the optical fibers and the at least one fiber-shaped member are insertable thereinto, one end portion of an optical fiber and one end portion of a fiber-shaped member are held by the holding portion in a state of being inserted into a fiber insertion hole, an optical fiber extends to the outside of the ferrule beyond the second end surface, and the other end portion of the fiber-shaped member is located inside the ferrule, wherein three or more of the fiber insertion holes are provided in the holding portion so as to be arranged in a second direction intersecting with the first direction, and fiber-shaped members are inserted into fiber insertion holes of a central side of the holding portion in the second direction among the plurality of fiber insertion holes.

4 . The optical connection assembly according to claim 3 , wherein twelve of the fiber insertion holes are provided in the holding portion, and
fiber-shaped members are inserted into the four fiber insertion holes of the central side of the holding portion in the second direction among the plurality of fiber insertion holes.

5 . The optical connection assembly according to claim 3 , wherein in an optical fiber, a covering is removed at a part located outside the ferrule.

6 . The optical connection assembly according to claim 3 , wherein the plurality of optical fibers are integrated at the outside of the ferrule.

7 . The optical connection assembly according to claim 6 , wherein the plurality of optical fibers is divided into two parts in the inside of the ferrule.

8 . The optical connection assembly according to claim 3 , wherein the other end portion of the optical fiber is attached to a second connector.

9 . (canceled)
