A system that reduces crosstalk and return loss within electrical communication connectors includes at least two compensating capacitors connected in series that compensate each offending capacitor. An additional inductive component that is connected between two compensating capacitors so that the adjustable inductance of the inductive component can be varied to modify the capacitive coupling effect achieved by the compensating capacitors as a function of frequency. A shape-neutral structure containing two compensating capacitors and one series inductive component in between is positioned so that each compensating capacitor is juxtaposed parallel to the offending capacitor. There is no direct contact between the shape-neutral structure and the transmission lines, and the shape-neutral structure does not change the shape of PCB traces and reduces both crosstalk and return loss.

An electrical connector and a ground system which includes ground contacts and ground shields positioned proximate the ground contacts. The ground contacts have receiving sections, securing sections and mounting sections. The receiving sections have first engagement portions and second engagement portions. The ground shields have a nonplanar configuration, with portions of the ground shields passing between signal contacts. Surfaces of the securing sections of the ground contacts are positioned in mechanical and electrical engagement with surfaces of the ground shields, providing first ground contact areas across which ground currents may flow. The first engagement portions of the ground contacts are provided in electrical and mechanical engagement with the surfaces of the ground shields, providing second ground contact areas across which the ground currents may flow. The second ground contact areas are spaced from the first ground contact areas to allow the ground currents to properly flow through the entire ground shields.

Communications connectors include a housing and a plurality of substantially rigid conductive pins that are mounted in the housing. The conductive pins are arranged as a plurality of differential pairs of conductive pins that each include a tip conductive pin and a ring conductive pin. Each conductive pin has a first end that is configured to be received within a respective socket of a mating connector and a second end. The tip conductive pin of each differential pair of conductive pins crosses over its associated ring conductive pin to form a plurality of tip-ring crossover locations.
