High density electrical connector having a printed circuit board

A high density mated pair connector having a printed circuit board ("PCB") and a contact module to facilitate electrical connections through the mated pair connector. A receptacle assembly accepts receptacle cables and electrically connects the receptacle cables to a receptacle PCB coupled with a receptacle body. A plug assembly accepts plug cables and electrically connects the plug cables to a plug PCB coupled with a plug body. A contact module is coupled with the plug body and has a plurality of contacts. A first end of the plurality of contacts electrically connects with the plug PCB. A second end of the plurality of contacts is configured to electrically connect with the receptacle PCB. Upon mating, the plurality of contacts of the contact module couple to the receptacle PCB, thus electrically connecting the receptacle cables with the plug cables.
