  • Publication number: 20070297726
    Abstract: A ferrule has at least one row of optical fiber openings to hold optical fibers. The ferrule also includes a lead-in portion for each of the optical fiber openings to assist in positioning the optical fibers into the optical fiber openings in the ferrule. The optical fiber openings in the ferrule are slightly smaller and have a similar spacing allowing for better fill between the optical fiber openings. A mold core that corresponds to the ferrule is disclosed. The mold core encapsulates at least a portion of the optical fiber opening forming pins, eliminating build up and breakage of the pins.

  • Patent number: 7280732
    Abstract: A transition assembly is provided that has a base with two sides and a plurality of optical fibers attached to each of the two sides. The optical fibers are attached to the base, with a protective covering over the optical fibers. The optical fibers are in a ribbonized format at one end of the transition assembly and in an individual format at the other end. The individual optical fibers may have protective tubes disposed thereon for protection.

  • Patent number: 7245813
    Abstract: A dust cap for an optical ferrule is provided that has a sleeve with a first end and second end, the second end having at least one depression configured to engage a portion of the end face of an optical ferrule. The dust cap prevents dirt and debris from contaminating the front face of the optical ferrule if the optical ferrule has open guide pin holes.

  • Publication number: 20030174953
    Abstract: An optical circuit is provided having a plurality of legs, each of which may have one or more optical fibers bound together by a matrix material, arranged in a stacked configuration in such a manner as to reduce, if not eliminate, the stress to which the optical fibers are subjected. The optical circuit includes a main body having a flexible substrate and a plurality of optical fibers mounted upon the substrate and lying in a common plane. The plurality of legs extend outwardly from an edge of the main body. The legs are disposed in a stacked configuration in which at least one leg overlies another leg. As such, at least one leg lies at least partially outside of the common plane defined by the substrate. A method for fabricating the optical circuit is also provided.

  • Patent number: 6442323
    Abstract: A flexible optical circuit is provided that includes at least one layer formed of a foam material in order to provide strain relief for the optical fibers and to improve the crush resistance of the flexible optical circuit. The flexible optical circuit includes a substrate and at least one optical fiber disposed upon the substrate. In one embodiment, the substrate is formed of a foam material, such as a silicone or polyurethane foam. The flexible optical circuit can also include a protective layer disposed upon at least a portion of the substrate so as to overlie at least a segment of at least one optical fiber, such as those segments at which the stress is concentrated. In addition to or instead of forming the substrate from a foam material, the protective layer may be formed of a foam material.

  • Patent number: 6085003
    Abstract: A fiber optic connector is provided which includes a free floating ferrule so as to reliably withstand significant side-pull forces. In other words, the fiber optic connector is designed such that the minimum rotational angle of the combination of the ferrule and the pin clamp within the connector housing is greater than the maximum rotational angle of the connector housing within an adapter. In order to permit the ferrule to be free floating, the fiber optic connector can provide increased clearance or spacing between the combination of the ferrule and the pin clamp and the connector housing. For example, the inner sidewalls of the forward end of the connector housing may have either a beveled or a stepped profile in longitudinal cross-section so as to provide additional clearance at the forwardmost portion of the ferrule.

  • Patent number: 6005991
    Abstract: The printed circuit board assembly includes a printed circuit board having an interior portion upon which a flexible optical circuit is mounted and edge portions surrounding the interior portion. The flexible optical circuit includes a pair of at least partially flexible sheets and a number of optical fibers sandwiched between the flexible sheets. The first ends of the optical fibers extend toward an edge portion of the printed circuit board. In order to conserve space along the edge of the printed circuit board while providing interconnections for each of the optical fibers, a multifiber connector can be mounted upon the respective first ends of a predetermined number of optical fibers. Connectors, such as single fiber connectors, are also mounted to the second ends of the optical fibers.

  • Patent number: 5743785
    Abstract: The method and associated apparatus of the present invention polishes the front face of a ferrule with first and second slurries such that an end portion of each optical fiber which extends through and is held by the ferrule protrudes beyond the preferentially etched front face of the ferrule by a preselected length. In order to preferentially etch the front face of ferrule as desired, the front face of the ferrule is polished with a first slurry having a plurality of suspended particulates of a first predetermined size on average which initiates the preferential etch of the ferrule relative to the optical fibers. Thereafter, the front face of the ferrule is polished with a second slurry having a plurality of suspended particles of a second predetermined size on average.
