A communication connector has a housing for receiving a communication plug, a printed circuit within the housing, a switch which actuates the printed circuit board, and a translating crossbar which engages the switch. The printed circuit board is moved dependent upon a type of plug inserted. The movement of the circuit board can help to selectively engage one of two sets of circuit traces and groupings of contacts.

Embodiments of an electrical plug may include an electrical circuit having an input-side interface with at least one input-side contact point for connecting at least one signal conductor of at least one electrical lead. In some embodiments the electrical circuit has an output-side interface with at least one output-side contact point. The electrical circuit may have a transmission option from the input-side interface to the output-side interface for controlling impedance, and the design of the input-side interface in some embodiments may differ from the design of the output-side interface.

A modular RJ45-type plug apparatus is provided for forming a connector interface with a connector jack in a high speed data transmission network. A housing comprises an insulative front portion and a conductive shield portion attachable to define an interior, within which is positioned a contact subassembly including a first PCB having cable mounting pads on one end and through holes for elongate plug contacts on the other end. The contacts are connected on one end to the first PCB and on a second end to a second PCB, with bridge portions therebetween collectively defining a jack contact interface. The second PCB comprises desired electrical characteristics which provide the apparatus with certain capacitance compensation properties, wherein the capacitance compensation is offset from a signal path defined between the jack-plug connector interface and the cable pairs.

Embodiments of the present invention relate to designs for network jacks which can be used for cable connectivity. In an embodiment, the present invention is an RJ45 jack that utilizes a thin dielectric film between two layers of PICs that provide crosstalk compensation by way of their geometry. Compensation is achieved by way of capacitor plates which sandwich a thin dielectric film. This allows for the layers of PICs to be in close proximity and achieve higher coupling where desired, allowing a greater amount of compensation to occur close to the plug/jack contact point. This can have the effect of moving compensation closer to the plug/jack contact point, which in turn may reduce the amount of compensation needed further along the data path.
