  • Patent number: 5966487
    Abstract: A Media Interface Adapter (MIA) module is provided for converting Fiber Channel data signals from a first copper transfer medium to a second alternate transfer medium. The MIA includes an internal mounted printed circuit board containing the electronic components necessary to convert signals between the first copper medium and second alternate medium. A transmitter is provided for transmitting the data signals over the second alternate transfer medium, and a receiver is provided for receiving data signals over the second alternate transfer medium. Opposite the transmitter and receiver, a nine pin electrical D-sub connector is provided for connecting the module to the first copper transfer medium. The D-sub connector has a metal flange insertable into a connector mounting structures formed in the housing. The connector mounting structures being configured to partially overlap the flange of the D-sub connector.

  • Patent number: 5879173
    Abstract: A robust optoelectronic transceiver module which is quick, easy, and inexpensive to manufacture. The transceiver module has a main housing which consists of a potting box with potting material inserted therein. In addition, a circuit board is encased by the potting material. The circuit board has an optical subassembly mounted thereon. The optical subassembly extends outside of the potting box through a recess. Correspondingly, a recess cover is provided for forming a liquid tight seal between the recess cover, the potting box, and the optical subassembly. The module housing may be pluggable via release levers having detentes received in apertures of a receptacle and a pluggable connector of the module mated within the receptacle. The receptacle may include grounding means such as a ground clip mounted within the receptacle and a protective door to limit electromagnetic emissions.

  • Patent number: 5864468
    Abstract: A robust optoelectronic transceiver module which provides for static discharge and is quick, easy, and inexpensive to manufacture. The transceiver module has a main housing which consists of a potting box with potting material inserted therein. In addition, a circuit board is encased by the potting material. The circuit board has an optical subassembly mounted thereon. The optical subassembly extends outside of the potting box through a recess. Correspondingly, a recess cover is provided for forming a liquid tight seal between the recess cover, the potting box, and the optical subassembly. Furthermore, the module provides electrically conductive latches which are conductively connected, via tabs for forming an electrical connection, to a grounded structure, such as a computer chassis.

  • Patent number: 5636998
    Abstract: A pluggable male terminator for use with a female ribbon cable connector. The terminator is comprised of three basic parts that can snap together. The three members are a shroud having openings in the top, a PC board with pins extending from opposed surfaces, and a cover with recesses therein. The pins are complementary in shape and size to the openings in the shroud and the recesses in the cover. Further, the pins are aligned with the openings in the shroud and the recesses. For assembly, the pins on the PC board are inserted into the recesses in the cover openings in the shroud and the parts are pushed together. The pins extending from the shroud are adapted to be inserted into recesses in the female ribbon cable connector.
