A cable header connector includes a cable assembly having a contact sub-assembly and a ground shield coupled to and providing electrical shielding for the contact sub-assembly. The contact sub-assembly has a mounting block with contact channels therein. The contact sub-assembly has signal contacts received in the contact channels and extending between mating and terminating ends. The signal contacts are terminated to corresponding signal wires. The ground shield has walls extending along the signal contacts and has mating and terminating ends. The mating end is positioned either at or beyond the mating ends of the signal contacts. The terminating end is positioned either at or beyond the terminating ends of the signal contacts such that the ground shield provides shielding along the entire length of the signal contacts.

1. A cable header connector comprising: a cable assembly comprising 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 having a mounting block having contact channels therein, the contact sub-assembly having a single differential pair of signal contacts each received in corresponding contact channels, the signal contacts extending between mating ends and terminating ends, the signal contacts being terminated to corresponding signal wires of the cable at the terminating ends; andthe ground shield having walls extending along the signal contacts the walls defining a receptacle, the ground shield having a mating end and a terminating end, the mating end of the ground shield being positioned either at or beyond the mating ends of the signal contacts, the terminating end of the ground shield being positioned either at or beyond the terminating ends of the signal contacts such that the ground shield provides shielding along the entire length of the signal contacts to provide electrical shielding for the single differential pair of signal contacts from signal contacts of another contact sub-assembly, wherein the receptacle is configured to receive only the single differential pair of signal contacts such that the ground shield electrically shields the single differential pair of signal contacts from any other differential pair of signal contacts. 2. The cable header connector of claim 1, wherein the ground shield entirely peripherally surrounds the termination of the signal contacts to the signal wires. 3. The cable header connector of claim 1, wherein the ground shield extends along a portion of the cable such that the ground shield peripherally surrounds at least part of a cable shield of the cable. 4. The cable header connector of claim 1, further comprising a ground ferrule configured to be mounted to an end of the cable, the ground shield extending along and peripherally surrounding a portion of the ground ferrule. 5. The cable header connector of claim 1, wherein the ground shield comprises an upper shield and a lower shield coupled to the upper shield, a receptacle being defined between the upper and lower shields, the contact sub-assembly being received in the receptacle and the receptacle being configured to receive only the single differential pair of signal contacts such that the lower shield and the upper shield electrically shield the single differential pair of signal contacts from any other differential pair of signal contacts. 6. The cable header connector of claim 1, wherein the ground shield includes a shroud at the mating end, the shroud being C-shaped and having an open side, the shroud peripherally surrounding the single differential pair of signal contacts to electrically shield the single differential pair of signal contacts from any other differential pair of signal contacts on three sides thereof. 7. The cable header connector of claim 1, wherein the ground shield comprises an upper shield and a lower shield, the lower shield having a receptacle that receives the contact sub-assembly therein, the upper shield having side walls, the lower shield having side walls, the side walls of the upper shield engaging the side walls of the lower shield to create continuous ground paths along the sides of the single differential pair of signal contacts. 8. The cable header connector of claim 1, wherein the ground shield comprises an upper shield and a lower shield, the upper shield comprising press-fit features, the lower shield comprising press-fit features engaging corresponding press-fit features of the upper shield to secure the lower shield to the upper shield by an interference fit. 9.
