Abstract: A receptacle for use with a receptacle connector mounted to a host circuit board within a chassis of a host system, the receptacle comprising: (a) a housing having a front, a back wall, a top wall, a bottom wall, and side walls and defining a cavity for receiving a module, the bottom wall having a bottom opening with the receptacle connector being disposed therein when the receptacle is mounted to the host circuit board, the back, top, and side walls defining planes which completely contain the receptacle when the receptacle is mounted to the host circuit board; and (b) a plurality of elongated members extending down from the housing past the bottom wall and adapted for electrical connection to the host circuit board such that the walls are electrically connected to the host circuit board.

Abstract: Transceiver receptacles (12a, 12b) are mounted on both sides of an intermediate circuit board (10). Each of the transceiver receptacles includes a host connector (14) disposed within a shielding cage (16). The host connector is electrically connected to the intermediate circuit board and is configured for electrically mating with a respective transceiver module (20), and the shielding cage is configured to receive and guide the respective transceiver module into mating engagement with the host connector. An electrically conductive bezel spacer (36) is disposed in gaps between the shielding cages to reduce propagation of electromagnetic interference. Mating connectors (41, 42) electrically connect the intermediate circuit board (10) to a main circuit board (40).

Abstract: A receptacle for a pluggable module includes a housing having a front, a back wall, a top wall, a bottom wall, and side walls and defining a cavity for receiving a module. The bottom wall has a bottom opening to receive a receptacle connector, and the front has a front opening to receive the module. The walls of the housing are made from a conductive material. A plurality of elongated members extend down from the housing past the bottom wall. The elongated members are adapted for electrical connection to a host circuit board such that the walls of the housing are electrically connected to the host circuit board.

Abstract: Transceiver circuitry (10, 200) for use in a GBIC module uses readily available off the shelf components to satisfy the specifications of the GBIC standard. In both passive and active modules, a voltage divider (98) and parallel transistors (94, 96, 100) are utilized to insure that the differential voltage of the received differential signal is at an acceptable level. In active modules, a diode cross over quad (84) is utilized to extend the input range of a low input differential receiver (78) and a coaxial cable driver (60) designed to drive 50 ohms is utilized to drive 150 ohms.

Abstract: A shielding cover for a GBIC module (30) including a pair of cover parts (38, 40) formed with complementary features to surround a printed circuit board (32) of the module. A pair of latch members (42, 44) hold the two cover parts together and also provide a latching function when a module is inserted into a guide structure (12) mounted to a host board.
