  • Publication number: 20170205584
    Abstract: A molded waveguide side-facet coupler to facilitate an optical connection between optical side-facets and a fiber optic connector is disclosed. Instead of molding the side-facet coupler with the external mounting surface disposed on an external surface of the mold, the mold for the side-facet coupler is provided such that the mounting surface of the side-facet coupler is provided as a molded internal recess surface. The moldable material for the side-facet coupler is disposed around a recess core that is part of the mold, thereby forming a unitary component having at least one internal recess surface for providing an external mounting surface for the side-facet coupler. As the molded material cures around the core structure, the external surfaces of the unitary component pull away from internal surfaces of the mold, and shrink around the core structure. Thus, the internal recess surface of the unitary component is formed within narrower, repeatable tolerances.

  • Patent number: 9651753
    Abstract: A fiber optic ribbon cable includes a stack of fiber optic ribbons, strength members surrounding the stack, and a jacket defining an exterior of the cable. The jacket forms a cavity through which the stack and the strength members extend. The stack has a bend preference, but the strength members are positioned around the stack or are flexible in bending such that the strength members do not have a bend preference. Furthermore, the jacket is structured such that the jacket does not have a bend preference. The cavity is sized relative to the stack in order to allow the stack to bend and twist within the cavity with respect to the jacket as the cable bends, facilitating movement of the optical fibers of the fiber optic ribbons to low-stress positions within the cavity and decoupling the bend preference of the stack from transfer to the jacket.

  • Patent number: 9645339
    Abstract: Disclosed are optical ports and devices having a minimalist footprint. Specifically, the optical ports and devices have a footprint where the optical elements are exposed at a frame of the device. Additionally, a frame of the device provides a portion of the mating surface for engaging a complimentary optical plug during mating with the optical port on the device. This minimalist footprint advantageously allows for a smaller portion of the optical port to be exposed to the environment and subject to damage and/or wear. Further, the optical port provides a clean and sleek optical port on the device with a relatively small surface that may be cleaned or wiped by the user as necessary.
