  • Patent number: 7959467
    Abstract: A transceiver module that utilizes a side contact spring portion to ground a shielded cable that is plugged into the transceiver module. In one example embodiment, a transceiver module includes a housing, a jack, and a side contact spring portion. The housing is operative to be electrically connected to chassis ground when the transceiver module is received within a host port. The jack is defined in the housing and operative to receive a shielded plug. The side contact spring portion is substantially implemented within the jack and is configured to be in electrical contact with both the housing and a conductive element of the shielded plug received by the jack such that a chassis ground is established between the housing and the shielded plug and such that a moveable bail pivot lever is able to move without disrupting the electrical contact between the side contact spring portion and the housing and/or the conductive element of the shielded plug.

  • Publication number: 20110080008
    Abstract: One embodiment includes a latching mechanism having a latch, a cam and a slider. The cam is configured to rotate about an axis of rotation. The cam is also configured to displace an end of the latch when the cam is rotated about the axis of rotation. The slider is operably connected to the cam and is configured to cause the cam to rotate about the axis of rotation. Some embodiments also include a retaining cover and a boot. The retaining cover secures a second end of the latch to a module in which the latching mechanism is implemented.

  • Patent number: 7917037
    Abstract: A shield device for preventing the emission of electromagnetic interference (“EMI”) from an optoelectronic device, such as an optical transceiver, is disclosed. In particular, an EMI shield is disclosed for placement within an optical transceiver module in order to intercept and absorb EMI produced by electronic components included within the transceiver. This absorption by the EMI shield prevents EMI from escaping the optical transceiver module and interfering with other electronic components that are typically placed in close proximity to the transceiver. The EMI shield in one embodiment includes a sheet of EMI absorbing material that is sized for placement within the transceiver. The EMI shield can be interposed between an outer shell of the transceiver and electronic components located on a printed circuit board that is disposed within the transceiver. The proximity of the EMI shield to the EMI-producing electronic components maximizes EMI absorption by the shield.

  • Patent number: 7559704
    Abstract: A system for retaining an optical subassembly in a shell of a communications module is disclosed. The system reduces stress imposed on a hermetic package of the optical subassembly during lead interconnection procedures while ensuring thermal contact of the package with a thermal pad mounted in the shell. In one embodiment, the system includes a spring clip comprising a head portion that defines a seating surface, as well as first and second arms. The seating surface is shaped to engage an outer surface of a nosepiece of the optical subassembly. The first and second arms extend from the head portion so as to define a “U”-shaped configuration with the head portion. The head portion is shaped so as to provide a resilient force against a flange of the nosepiece when the flange and spring clip are received in a groove defined in the shell during assembly.

  • Patent number: 7507111
    Abstract: An integrated latching mechanism for use with a user pluggable electronic module, such as an opto-electronic transceiver module, is disclosed. The latching mechanism allows the user to selectively latch the module within a corresponding host port by manipulation of a pivot lever. Movement of the pivot lever causes a locking pin to extend and latch the module within the port. Conversely, movement of the pivot lever can disengage the locking pin and thereby allow the user to extract the module from within the port. The pivot lever can further include a biasing member that biases the pivot lever in a locked position.

  • Patent number: 7481656
    Abstract: A mounting system for securing a printed circuit board in a communication module, such as an optical transceiver module, is disclosed. In one embodiment, the transceiver module includes an outer shell and an enclosure that cooperate to contain the printed circuit board therein. The mounting system comprises first and second pins, wherein each pin includes a first end passing through respective holes coaxially defined in both the shell and the printed circuit board. The pins also each have a second end that includes a head. The head is positioned in a recess defined in an exterior portion of the shell such that the head does not interfere with insertion or removal of the transceiver module from a slot of a host device. Further, the second pin is electrically connected with both the outer shell and enclosure to prevent emissions of electromagnetic interference from the distal end of the transceiver.
