Abstract
A connector is provided for simultaneously improving both the NEXT high frequency performance when low crosstalk plugs are used and the NEXT low frequency performance when high crosstalk plugs are used. The connector includes a first compensation structure provided on an inner metalized layer of the PCB at a first stage area of the PCB, and a second compensation structure, provided at a second stage area of the PCB, for increasing compensation capacitance with increasing frequency.
