ABSTRACT:
An optical connector for splicing a rear end of a pre-assembled optical fiber that is mounted within an optical ferrule with a tip of a second optical fiber is provided. The optical connector includes a connector body and an anchor mechanism for anchoring the second optical fiber to the connector body. The anchor mechanism includes a holder for holding the second optical fiber, and connecting portion which anchors the holder to the connector body. The length of the second optical fiber from the holder to the tip is longer than the distance from the holder to the rear end of the pre-assembled optical fiber. The rear end of the pre-assembled optical fiber is a curved convex end surface or an end with a diameter-reducing portion, and is PC-connectable to the tip of the second optical fiber.
