Abstract: Pluggable transceiver assembly includes a transceiver body having first and second plug portions and a common base portion that joins the first and second plug portions. The first and second plug portions are separated from each other by an elongated wall-receiving gap that is sized and shaped to receive a receptacle wall of a receptacle assembly. The pluggable transceiver assembly also includes a communication sub-assembly having a transceiver substrate that includes first and second plug sections and a shared section that joins the first and second plug sections. The first and second plug sections extend toward a leading end of the transceiver body from the shared section to substrate edges of the first and second plug sections, respectively. The substrate edges include electrical contacts configured to engage a corresponding receptacle connector of the receptacle assembly.

Abstract: An electrical connector includes a housing and a plurality of signal conductors held within the housing. The housing includes a mating shroud protruding forward from a front wall of the housing and defining a port that receives a mating circuit card therein. Each of the signal conductors includes a mating contact disposed within the mating shroud and a mounting contact that projects beyond a bottom end of the housing to electrically connect to a circuit board. The mounting contacts are located within a termination area of the electrical connector. The housing defines a nesting cavity extending rearward from the front wall along the bottom end. The nesting cavity is disposed between the mating shroud and the termination area along a longitudinal axis of the electrical connector. The nesting cavity is configured to accommodate a discrete, second connector that is mounted to the circuit board.

Abstract: A heat spreader includes a main body extending between a front and a rear configured to be mounted to a cage and heat transfer fingers cantilevered forward from the front of the main body. The heat transfer fingers each have a fixed end, a distal end, a top, a bottom and mating edges facing each other across gaps. The heat transfer fingers are configured to be received in corresponding channels between heat transfer fins of a pluggable module as the pluggable module is installed in the cage through the front end with the gaps receiving the heat transfer fins. The mating edges are configured to face and be thermally coupled to corresponding heat transfer fins. The heat transfer fingers transfer heat from the heat transfer fins rearward toward the distal ends and into the main body.

Abstract: Printed circuit includes a planar substrate having opposite sides and a thickness extending therebetween. The sides extend parallel to a lateral plane. The printed circuit also includes a plurality of conductive vias extending through the planar substrate in a direction that is perpendicular to the lateral plane. The conductive vias include ground vias and signal vias. The signal vias form a plurality of quad groups in which each quad group includes a two-by-two array of the signal vias.

Abstract: An electrical connector that includes a housing configured to be coupled to a mating connector. The connector has signal contacts held in signal contact openings. The signal contacts are arranged in arrays of quad groups. Each of the quad group has a set of four contacts arranged in row pairs and column pairs. The signal contacts of each quad group are configured to carry relational signals with each other signal contact in the quad group. Each signal contact is configured to electrically couple to a signal contact of the mating connector. The connector also includes ground shields held in corresponding ground shield openings. The ground shields have walls surrounding a corresponding quad group of signal contacts and provides electrical shielding from adjacent quad groups of signal contacts. The ground shields have mating ends for mating with corresponding ground contacts of the mating connector.

Abstract: A cable connector is provided. The cable connector includes a connector housing having a cavity for receiving a contact along an axis, and the cavity has a protrusion therein. The protrusion extends through the axis so that as the contact is inserted into the cavity along the axis, the contact is deflected by the protrusion until the contact moves past the protrusion into a locked position. The contact has a body section with at least one wing extending therefrom. The wing contacts the protrusion as the contact is inserted into the cavity along the axis causing the contact to rotate about the axis.
