  • Patent number: 6874944
    Abstract: An optical fiber connector mounting assembly mounts an optical fiber connector such that the connector is located outside of a faceplate to facilitate access to an end face of the connector. The mounting assembly secures and protects the optical fiber connector. In one embodiment, the optical fiber connector includes a strain relief boot that allows the connector to be moved within a limited bend radius.

  • Patent number: 6788870
    Abstract: An isothermal fiber optic tray is used to hold optical fiber, such as erbium doped fiber in an erbium doped fiber amplifier (EDFA). The isothermal fiber optic tray comprises a thermally conductive inner structure providing a substantially isothermal cavity. An insulating outer structure is positioned adjacent first and second sides of the thermally conductive inner structure.

  • Patent number: 6477053
    Abstract: A heat sink used in an electronic assembly includes mounting surfaces on a first side of a base portion and extended heat dissipating surfaces (e.g., fins) extending from a second side of the base portion. One or more electronic component boards, such as printed wiring boards (PWBs), are mounted to the mounting surfaces on the heat sink at one or more levels. Some of the mounting surfaces can be formed on mounting ridges, which define channels. Ventilation apertures located between the fins extend through the base portion such that air is drawn through the channels and up through the apertures creating a “chimney” effect. The heat sink is also grounded to at least one of the PWBS and electrically isolated from the chassis. Isolator bushings can be mounted in one or more of the fins for receiving pins extending from the chassis to insure mechanical support and isolation/dampening and to insure electrical isolation from the chassis.
