An optical interposer for optically coupling light between an OED supported on a substrate and an optical fiber, the interposer comprising: (a) an interposer of an optically-clear moldable material comprising at least the following features: (b) a port for receiving a ferrule containing at least one optical fiber, the port comprising an interface surface positioned to optically couple with an end face of the optical fiber; (c) an active lens adapted to optically couple with an OED, the active lens and the interface surface optically coupled along an optical path in the interposer; (d) a protrusion extending backward from the port, the protrusion defining a first register surface, the first register surface being a certain distance from the optical path such that, when a second register surface of a ferrule containing the optical fiber contacts the first register surface, the ferrule is aligned with the port such that the port can receive a front portion of the ferrule if the ferrule is pushed forward.

Interposer with alignment features

Transceiver receptacles ( ) are mounted on both sides of an intermediate circuit board ( ). Each of the transceiver receptacles includes a host connector ( ) disposed within a shielding cage ( ). The host connector is electrically connected to the intermediate circuit board and is configured for electrically mating with a respective transceiver module ( ), 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 ( ) is disposed in gaps between the shielding cages to reduce propagation of electromagnetic interference. Mating connectors ( ) electrically connect the intermediate circuit board ( ) to a main circuit board ( ).

Stacked transceiver receptacle assembly

A receptacle for receiving a module and electrically connecting said module to a host circuit board mounted within a chassis of a host system, said chassis having a bezel opening which has an offset a certain distance above said host circuit board: (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 to receive a receptacle connector, the front having a front opening to receive the module, the walls comprising a conductive material; (b) a plurality of elongated members extending down from the housing past the bottom wall and adapted for electrical connection to a host circuit board such that the walls are electrically connected to the host circuit board; and (c) at least one standoff extending down from the housing, the standoff being more toward the front of the housing than the rear, when the housing is mounted to the host circuit board, the standoff contacts the circuit board and causes the front of the housing to be raised above the rear of the housing, the front of the housing being raised above the host circuit board by a distance approximately the same as that of the offset.

Pluggable module and receptacle

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.

Transceiver circuitry ( ) 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 ( ) and parallel transistors ( ) 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 ( ) is utilized to extend the input range of a low input differential receiver ( ) and a coaxial cable driver ( ) designed to drive 50 ohms is utilized to drive 150 ohms.
