Abstract:
Patch cords are provided that include a communications cable that has at least first through fourth conductors and a plug that is attached to the cable. The plug includes a housing that receives the cable, a printed circuit board, first through fourth plug contacts, and first through fourth conductive paths that connect the first through fourth conductors to the respective first through fourth plug contacts. The first and second conductors, conductive paths, and plug contacts form a first differential transmission line, and the third and fourth conductors, conductive paths, and plug contacts form a second differential transmission line. Each of the first through fourth plug contacts has a first segment that extends longitudinally along a first surface of the printed circuit board, and the signal current injection point into the first segment of at least some of the first through fourth plug contacts is into middle portions of their respective first segments.
