Abstract
A cable card assembly includes a circuit card and cables terminated to the circuit card. Each cable has signal conductors, an insulator, and a cable shield. The cable card includes conductor holders forward of the insulators manufactured from a dielectric material and having conductor channels that receive the signal conductors. The cable card assembly includes ground shields coupled to the circuit card providing electrical shielding for the cables. Each ground shield includes a side walls and an end wall. The end wall has an end wall connecting portion coupled to the cable shield. The first side wall has a first side wall connecting portion coupled to the cable shield. The second side wall has a second side wall connecting portion coupled to the cable shield.
