Patent number: 8573856Abstract: A method for preparing a ferrule assembly avoids polishing while providing adequate control over fiber end protrusion and co-planarity. A distal end of the fiber is prepared before securing the fiber in a ferrule, and before or after inserting the fiber into the ferrule. The prepared fiber is manipulated to provide a desired spatial relationship between the fiber end and the ferrule's end face, and then secured to maintain the desired spatial relationship. Preferably, the fiber end is prepared using a laser cleaving technique to provide a suitable end without abrasive polishing. An interferometer may be used to obtain measurements, during manipulation of the prepared fiber within the ferrule, that indicate whether the prepared fiber is satisfactorily positioned. In accordance with other aspects of the invention, a ferrule assembly prepared in accordance with the method, and a connector or other optical package including such a ferrule assembly are provided.Type: GrantFiled: July 30, 2010Date of Patent: November 5, 2013Assignee: Tyco Electronics CorporationInventors: Joshua L.

Patent number: 8506174Abstract: An optical connector includes a second operation lever extending rearward from a first operation lever. By pressing a rear end portion of the second operation lever up, or pressing the second operation lever forward, the first operation lever can be inclined forward. In this way, a front end portion of the first operation lever presses a rear end portion of a locking lever down, and disengages the locking lever and an optical adapter from each other. Thus, the optical connector can be detached from the optical adapter.Type: GrantFiled: June 1, 2011Date of Patent: August 13, 2013Assignee: Suncall CorporationInventor: Masaya Nakagawa

Publication number: 20130195407Abstract: An optical fiber connector comprises a ferrule having a rear end, a chuck located rearward of the ferrule, a ring having a front end, and a coil spring. The ring is attached to the chuck so as to surround the chuck. The optical fiber connector holds an optical fiber which is inserted from a rear end of the optical fiber connector. In detail, when the optical fiber is inserted into the optical fiber connector, an end of the optical fiber passes through the chuck to be accommodated in the ferrule. The coil spring presses the ring forward (toward the ferrule) so that the chuck is squeezed to hold the inserted optical fiber. When the ring is moved rearward by a stopper inserted between the rear end of the ferrule and the front end of the ring, the chuck is released to release the optical fiber.Type: ApplicationFiled: November 29, 2012Publication date: August 1, 2013Applicants: ASAHI GLASS COMPANY, LIMITED, JAPAN AVIATION ELECTRONICS INDUSTRY, LIMITEDInventors: Japan Aviation Electronics Industry, Limited, Asahi Glass Company, Limited
