Plug connector having end node termination module

An electrical connector system comprising:

• a header connector including a header housing holding header contacts, the header housing including a receptacle, the header contacts including mating ends in the receptacle;
• and
• a plug connector received in the receptacle and mated to the header contacts, the plug connector comprising:
• a plug housing having a mating end and a cable end, the mating end configured to be mated with a header connector, the plug housing including first and second module channels between the mating end and the cable end;
• a data module received in the first module channel, the data module including a data module housing holding a signal contact terminated to an end of a signal wire of a data cable, the signal contact including a mating end configured to be mated to the header connector;
• an end node termination module received in the second module channel, the end node termination module including a termination module housing with a pocket, the end node termination module including a signal processing assembly received in the pocket, the signal processing assembly including an end node printed circuit board (PCB) with an end node control circuit, the signal processing assembly including a signal processing component mounted to the end node PCB for processing signals on the end node control circuit, the end node PCB includes a perimeter edge between opposite surfaces of the end node PCB, the signal processing component mounted to the first surface, the end node PCB including a signal edge pad along the perimeter edge, the signal edge pad coupled to the end node control circuit;
• and
• a jumper contact held by the plug housing, the jumper contact including a signal contact mating interface electrically connected to the signal contact and an end node mating interface electrically connected to the signal edge pad of the end node PCB to electrically connect the signal contact to the end node control circuit within the plug connector.
