Plug connector having data module

A 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 a module channel between the mating end and the cable end;
• a data cable including a pair of unshielded signal wires arranged in an insulator, the pair of signal wires being twisted along the length of the data cable;
• and
• a data module received in the module channel, the data module including a data module housing extending between a front and a rear, the data module housing including signal contact channels holding a pair of signal contacts terminated to ends of the signal wires of the data cable, each signal contact including a mating end configured to be mated to the header connector and a terminating end terminated to the corresponding signal wire, the data module housing including a partition wall separating a first wire channel and a second wire channel, the first and second wire channels receiving the corresponding signal wires, the partition wall extending to the insulator.

A 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 a power contact channel between the mating end and the cable end, the plug housing including a first module channel between the mating end and the cable end, the plug housing including a second module channel between the mating end and the cable end;
• a power contact received in the power contact channel, the power contact being terminated to a power cable, the power contact including a mating end configured to be mated to the header connector;
• a data module received in the first module channel, the data module including a data module housing extending between a front and a rear, the data module including a data cable extending from the rear, the data cable including a pair of unshielded signal wires arranged in an insulator, the pair of signal wires being twisted along the length of the data cable, the data module housing including signal contact channels holding a pair of signal contacts and signal wire channels holding the pair of the signal wires, each signal contact including a mating end configured to be mated to header contacts of the header connector and a terminating end terminated to ends of the signal wires of the data cable, the signal contact channels being open at the front of the data module housing for mating with the header contacts, the data module housing including access windows along sides of the data module housing open to the signal contact channels to access the signal contacts in the signal contact channels;
• 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 having a signal processing component mounted to the end node PCB to control the end node control circuit;
• and
• jumper contacts held by the plug housing, each jumper contact including a signal contact mating interface received in the corresponding access window of the data module housing to electrically connect to the corresponding signal contact, each jumper contact including an end node mating interface electrically connected to the end node termination module to electrically connect the signal contacts to the end node control circuit within the plug connector.
