A cable header connector includes a contact module having a support body and a plurality of cable assemblies held by the support body and arranged in a column. The cable assemblies include a contact sub-assembly configured to be terminated to a cable, and a ground shield coupled to and providing electrical shielding for the contact sub-assembly. The contact sub-assembly has a pair of signal contacts extending between mating ends and terminating ends. The signal contacts are terminated to corresponding signal wires of the cable at the terminating ends. A ground bridge is coupled to the support body and is electrically conductive. The ground bridge includes intercolumn bridges arranged between corresponding cable assemblies. The intercolumn bridges engage and are electrically connected to the ground shields of corresponding cable assemblies on both sides of the intercolumn bridges. The ground bridge electrically connects corresponding cable assemblies engaged by the intercolumn bridges.
