An electrical communication system includes a printed circuit board (PCB) having first and second ground plates and a plurality of signal vias and a plurality of ground vias extending between and through the first and second ground plates. Each of the plurality of signal vias are electrically connected to a respective conductive trace on a surface of the PCB. Cables connect to the PCB at a right angle, with a connector attached to an opposite side of the PCB. Each cable has two signal wires and a ground wire extending therefrom. The two signal wires define a differential pair. The signal wires are symmetrical with respect to the ground wire. Each of the signal wires electrically connects to a respective one of the plurality of signal vias. The ground wire connects to one of the plurality of ground vias. The cables are offset with respect to one another on the first and second ground plates and within the PCB.
