A pluggable module is provided and includes a pluggable body including a cavity. The pluggable body extends between a mating end and a cable end opposite the mating end. The mating end is configured to be plugged into a receptacle connector assembly. The pluggable body has a top wall, a bottom wall, a first side wall at a first side, and a second side wall at a second side. The pluggable module includes a cable assembly coupled to the pluggable body. The cable assembly includes an upper module circuit card, a lower module circuit card, upper cables terminated to the upper module circuit card and lower cables terminated to the lower module circuit card. The upper module circuit card includes upper contact pads proximate to an upper mating edge. The lower module circuit card includes lower contact pads proximate to a lower mating edge.
