Abstract: An optical connector kit includes a ferrule-with-optical-fiber and an accommodating housing for accommodating all connector parts constituting an optical connector, including the ferrule-with-optical-fiber. An optical fiber having a predetermined length is attached to the ferrule of the ferrule-with-optical-fibers, for which end face polishing processing is carried out. The connector parts include a plurality of connector parts into which another optical fiber is inserted when the rear end of the optical fiber of the ferrule-with-optical-fiber and the tip end of another optical fiber are fusion-spliced. In the accommodating housing, the connector parts are arranged in a line in the order of insertion of another optical fiber.

Abstract: To provide a fusion-spliced optical connector capable of easily performing a fusion-splicing operation at an actual site in a short time, without need to perform additional special operations. An optical connector component is configured to attach a short-length optical fiber to a ferrule including a capillary and a flange. The capillary comprises a minute through hole and a coated-portion storage hole formed in the capillary, the minute through hole to be stored therein the bare optical fiber portion of the short-length optical fiber and the coated-portion storage hole to be stored therein a part of a coated optical fiber portion of the short-length optical fiber continuous to the bare optical fiber portion. The flange includes a coated-portion penetrating hole formed in the flange to be penetrated therein a very short portion continuous to the part of the coated optical fiber portion stored in the coated-portion storage hole.
