  • 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.

  • 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.

    Abstract: Embodiments disclosed herein include pre-terminated fiber optic connector sub-assemblies, and related fiber optic connectors, cables, and methods. In certain embodiments, an optical fiber stub is pre-installed in a ferrule bore of a ferrule of a fiber optic connector sub-assembly, to provide the pre-terminated fiber optic connector sub-assembly. The optical fiber stub can be pre-installed in the ferrule bore prior to termination of the fiber optic connector sub-assembly. Because the pre-terminated optical fiber stub disposed in the ferrule bore is not directly accessible through a ferrule body of the ferrule when a field optical fiber is disposed in the ferrule bore for fusion splicing, the ferrule has properties that allow thermal energy to be directed through the ferrule body into the ferrule bore. In this manner, the optical fiber stub pre-installed in the ferrule bore can be fusion spliced with the field optical fiber to terminate a fiber optic cable.

  • Patent number: 8858090
    Abstract: Ferrule holders with an integral lead-in tube employed in fiber optic connector assemblies, and related components, connectors, and methods are disclosed. By integrating the integral lead-in tube as part of the ferrule holder, the integral lead-in tube may be less expensive to manufacture and easier to install. The integral lead-in tube may also be less susceptible to inadvertent removal by friction with a bonding agent syringe or by vibration during shipment. The ferrule holder may include a ferrule holder body and integral lead-in tube. The integral lead-in tube may guide an optical fiber from a rear end of a fiber optic connector to an internal passage of the ferrule holder, where the optical fiber may be further guided to a ferrule for precise alignment. The integral lead-in tube may also protect the optical fiber during installation, shipment, and use in the fiber optic connector.

  • Patent number: 8861908
    Abstract: This document discusses, among other things, a connector for an optical imaging probe that includes one or more optical fibers communicating light along the catheter. The device may use multiple sections for simpler manufacturing and ease of assembly during a medical procedure. Light energy to and from a distal minimally-invasive portion of the probe is coupled by the connector to external diagnostic or analytical instrumentation through an external instrumentation lead. Certain examples provide a self-aligning two-section optical catheter with beveled ends, which is formed by separating an optical cable assembly. Techniques for improving light coupling include using a lens between instrumentation lead and probe portions. Techniques for improving the mechanical alignment of a multi-optical fiber catheter include using a stop or a guide.
