Publication number: 20240027696Abstract: An optical connection structure including first optical fibers, second optical fibers, a first optical connector, and a second optical connector is disclosed. The first optical connector is configured such that each of first distal end portions of the first optical fibers protrudes from a first front end surface to the outside when the first optical connector and the second optical connector are connected to each other. Each of the first distal end portions is inserted into a corresponding second fiber hole of the second optical connector. The second optical connector is configured such that each of second distal end portions of the second optical fibers is moved rearward inside second fiber holes due to each of the first distal end portions respectively inserted into the second fiber holes. The first optical fibers and the second optical fibers are optically coupled to each other inside the second fiber holes.Type: ApplicationFiled: October 3, 2023Publication date: January 25, 2024Applicants: SUMITOMO ELECTRIC INDUSTRIES, LTD., SUMITOMO ELECTRIC OPTIFRONTIER CO., LTD., JAPAN COMMUNICATION ACCESSORIES MANUFACTURING CO., LTD., SUMITOMO ELECTRIC LIGHTWAVE CORP.Inventors: Masaki OMURA, Motoyoshi KIMURA, Takayuki YOKOCHI, Shunichi WATANABE, Junji FUKUI, Yasuyuki MAEKAWA, Takayuki SHIMAZU, Takashi KONDO, Kenichiro OTSUKA

Patent number: 11650375Abstract: A ferrule for retaining a plurality of optical fibers includes a front end surface; a rear end surface; a plurality of fiber retaining holes; an accommodation hole; and a void portion. The fiber retaining holes each extend from the front end surface toward the rear end surface along a first direction. The accommodation hole is connected to the plurality of fiber retaining holes. The void portion is provided in a region around the plurality of fiber retaining holes. The fiber retaining holes include constant diameter portions extending from the front end surface along the first direction. The void portion is provided along the constant diameter portions, and is aligned with the constant diameter portions in a plane perpendicular to the first direction. A minimum value of a width in the plane of the void portion differs from an inner diameter of the constant diameter portion.Type: GrantFiled: January 24, 2020Date of Patent: May 16, 2023Assignee: SUMITOMO ELECTRIC INDUSTRIES, LTD.Inventors: Fumiya Uehara, Masaki Omura, Takayuki Shimazu

Patent number: 11215763Abstract: An elastic member according to an embodiment is an elastic member that biases a ferrule retaining a plurality of optical fibers in a connecting direction. The elastic member is stored in an inner housing that accommodates the ferrule, the elastic member has a space in its inside into which a 16-fiber tape fiber is inserted, and the elastic member is in a noncircular shape in a cross section intersecting with the connecting direction. The elastic member includes a pair of first portions having an outer surface opposite to a pair of inner surfaces in an arc shape of the housing, the inner surfaces being opposite to each other along a first direction intersecting with the connecting direction and a pair of second portions opposite to the tape fiber along a second direction intersecting with both of the connecting direction and the first direction.Type: GrantFiled: May 21, 2019Date of Patent: January 4, 2022Assignees: JAPAN COMMUNICATION ACCESSORIES MANUFACTURING CO., LTD., SUMITOMO ELECTRIC OPTIFRONTIER CO., LTD., SUMITOMO ELECTRIC INDUSTRIES, LTD.Inventors: Yusuke Takai, Tsutomu Kamada, Motoyoshi Kimura, Fumiya Uehara, Masaki Omura

Publication number: 20210231884Abstract: An optical connector is disclosed. The optical connector includes a rear housing, an inner housing, and an outer housing. The inner housing includes a retaining hole to accommodate a ferrule. The outer housing is disposed on an outer periphery of the inner housing to cover a front portion of the inner housing. The outer housing rotates about the central axis with respect to the inner housing by a rotation guiding mechanism cooperating with an adapter for connecting the optical connector to another optical connector. The outer housing includes a front wall covering the distal end of the inner housing. The front wall includes at least one opening region. The opening region corresponds to a fiber exposed surface of the ferrule when the outer housing is rotated with respect to the inner housing from an initial position to a connected position by the rotation guiding mechanism.Type: ApplicationFiled: January 29, 2020Publication date: July 29, 2021Applicants: SUMITOMO ELECTRIC INDUSTRIES, LTD., Japan Communication Accessories Manufacturing Co., Ltd.Inventors: Kenichiro OTSUKA, Motoyoshi KIMURA, Masaki OMURA, Steve CHENG
