A modular jack connector compensates for plug characteristics via a controlled primary compensation in the immediate vicinity of the connector interface. A jack contact assembly is positioned within a jack housing and includes first and second sets of elongate contacts each having a plug contact portion and a signal output portion. Each elongate contact is configured such that their respective plug contact portions are coplanar and a signal path is defined between their plug contact portions and their signal output portions. A flexible circuit board is coupled proximate to the plug contact portions, and configured to provide capacitance compensation between respective contacts engaged thereby, wherein the capacitance compensation is offset from a signal path defined between the plug contact portions and the corresponding signal output portions.

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.
