  • Patent number: 8480310
    Abstract: Devices to enhance the reliability of optical networks and to reduce the cost of repair are disclosed in this invention. In particular, compact and inexpensive fiber optic union adapters with built-in protective isolation prevent the transfer of damage from one connectorized fiber optic cable to another. The fiber optic union includes a split sleeve with an interior channel and a fiber stub centrally located within the interior channel. The fiber stub makes direct optical contact with the cable endfaces to enable efficient optical transmission between interconnected cables while providing a low loss, low back reflection adiabatic transition between the waveguide cores of the two cables.

  • Patent number: 8272790
    Abstract: A cable connector assembly for outdoor connection to transceivers. Electrical connection between a component of the cable connector assembly and a connector inside an electronic assembly to which the cable connector assembly is attached is made through a force generated by a biasing member within the cable connector assembly. The biasing member may generate the force as the cable connector assembly is attached to an adapter. Once the cable connector assembly is disengaged from the adapter, the force is released, allowing easy removal of the cable connector assembly, without the need to release a latch. In an environmentally sealed connector in which access to a release mechanism may be restricted, such a structure provides ease of use for either electrical or optical connectors.
