Fiber End Held In Ferrule Patents (Class 385/78)
  • Patent number: 9164244
    Abstract: In an optical connector plug, a front end of the shutter member can move between a shield position to shield a front end face of a ferrule in an extension state and a non-shield position to expose the front end face of the ferrule to the front side of a housing in a reduction state, when a plug frame and a shutter holding member move between the extension state and the reduction state. In the optical connector plug, in a course in which the shutter holding member is engaged with holding portions protruding in an axial direction of the optical connector adaptor and a grip member moves from the extension state to the reduction state, the front end of the shutter member is spaced to face front ends of the holding portions in the axial direction.

    Abstract: A sealing enclosure is configured to connect to a mating enclosure. The sealing enclosure loosely receives a connector within a connector volume so that the connector, which may be of a standard type used in electronic or optic data transmission, may be displaced within a plug face at the forward end of the connector volume. The connector may compensate variations in the position of a mating connector with respect to the mating enclosure. The sealing enclosure allows to seal off the connector volume and engage the sealing enclosure with a mating enclosure in a single motion. This is affected by having a cable seal interposed between an inner body and an outer body. If the outer body is moved forward to engage the mating connector, the cable seal is squeezed between the cable and the inner body sealing off the connector volume at the rearward end of the inner body.

  • Patent number: 8961036
    Abstract: 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.

  • Publication number: 20150049989
    Abstract: Disclosed an optical connector plug to be fitted into a LC type adapter having a wide width opening and a narrow width opening. The optical connector plug includes a square cylindrical front housing; a plug frame for retaining a ferrule and slidable in the front housing, a locking housing connected to the plug frame and fitted in and locked with the LC type adapter. The guide portion on an upper part of the front housing has side wall surfaces coming in sliding contact with the opening having a narrow width at the upper part of the adapter and locking projections on the sidewall surfaces. The locking projections abut against an edge portion of an opening of the adapter when the locking housing is fitted into the adapter, so that the front housing is moved rearward, and a distal end portion of the ferrule projects outward from the opening.

  • Patent number: 8956057
    Abstract: 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.
