An interconnection system that includes a printed circuit board and an electrical connector. The printed circuit board has holes, into which contact tails from signal conductors in the connector are inserted. The connector is designed to carry differential signals so that the signal conductors are grouped in pairs. The tails of the signal conductors are offset toward each other. Further, the holes in the printed circuit boards have upper and lower portion. The upper portions align with the spacing of the contact tails of the signal conductors in the connector. The lower portions are offset from the upper portions, bringing the lower portions closer together, thereby increasing the coupling within the pair that carries one differential signal and reducing the crosstalk to adjacent pairs.
