Abstract
An electrical interconnection system with high speed, high density electrical connectors. The connectors incorporate electrically lossy material, selectively positioned to reduce crosstalk without undesirably attenuating signals. The lossy material may be molded through ground conductors that separate adjacent differential pairs within columns of conductive elements in the connector. However, regions of lossy material may be set back from the edges of the ground conductors to avoid undesired attenuation of signals. Also, the lossy material may be positioned in multiple regions along the length of signal conductors. The regions may be separated by holes, notches, gaps or other openings in the lossy material, which can be simply formed as part of a molding operation.
