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. Optionally, the printed circuit also includes signal traces that electrically couple to the signal vias. The signal traces may form a plurality of quad lines in which each quad line includes four of the signal traces. The four signal traces of each quad line may extend parallel to one another and be in a two-by-two formation.

An interposer includes a housing having a plurality of through-holes penetrating a first surface and a second surface and a signal contact pair composed of a pair of signal contacts. Each of the signal contacts includes a base portion press-fitted in one of the through-holes, a first contact beam extending from the base portion beyond the first surface, and a second contact beam extending from the base portion beyond the second surface. The pair of signal contacts are positioned adjacently to each other widthwise and are each asymmetrical with respect to a width direction. The signal contact pair has a plane-symmetrical shape with respect to the width direction.

A contact module includes a dielectric holder having first and second sides extending between a mating end and a mounting end. The contact module includes signal contacts held by the dielectric holder along a contact plane. The contact module includes a first ground shield coupled to the first side of the dielectric holder and providing electrical shielding for the signal contacts and a second ground shield coupled to the second side of the dielectric holder and providing electrical shielding for the signal contacts, the ground shield having skewer openings. The contact module includes ground skewers having posts extending from the first ground shield through the dielectric holder. The posts are electrically connected to the first ground shield and extend into corresponding skewer openings of the second ground shield to electrically connect the first ground shield to the second ground shield.
