Plug connector having end node termination module

A common mode end node termination module for a plug connector comprising:

• a termination module housing including a main body having a pocket, the main body including access windows open to the pocket;
• and
• a common mode signal processing assembly received in the pocket, the common mode signal processing assembly including an end node printed circuit board (PCB) with a common mode control circuit, the common mode signal processing assembly including a common mode signal processing component mounted to the end node PCB for processing signals on the common mode control circuit, the end node PCB including signal conductors and a ground conductor coupled to the common mode control circuit;
• wherein the end node PCB is configured to be electrically connected to signal contacts of the plug connector through the corresponding access windows and the end node PCB is configured to be electrically connected to an electrically grounded component of the plug connector through the corresponding access opening.

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 signal contacts terminated to ends of signal wires of a data cable, each signal contact including a mating end configured to be mated to the header connector;
• a common mode end node termination module received in the second module channel, the common mode end node termination module including a termination module housing with a pocket, the common mode end node termination module including a common mode signal processing assembly received in the pocket, the common mode signal processing assembly including an end node printed circuit board (PCB) with a common mode control circuit, the common mode signal processing assembly including a common mode signal processing component mounted to the end node PCB, the common mode control circuit being electrically connected to the signal contacts of the data module for processing signals on the common mode control circuit;
• and
• a ground jumper contact coupled to an electrically grounded component of the plug connector, the ground jumper contact including a ground contact mating interface electrically connected to the common mode end node termination module to electrically ground the common mode end node termination module.
