A ferrule assembly for terminating an electrical connector to a cable includes an inner ferrule, an outer ferrule and an inner ferrule sleeve. The inner ferrule has an inner surface and an outer surface. The inner ferrule is conductive and provides electrical shielding. The outer ferrule is positioned radially outside of the inner ferrule such that a cable shield of the cable is received between the inner ferrule and the outer ferrule. The outer ferrule secures the cable shield between the inner ferrule and the outer ferrule. The inner ferrule sleeve is positioned radially inside of the inner ferrule. The inner ferrule sleeve substantially fills the space between the inner ferrule and an inner jacket of the cable. The inner ferrule sleeve is dielectric and electrically isolating the inner ferrule from an inner conductor of the cable.
