Abstract:
A method for reducing crosstalk between a plurality of wires in a network cable using a network cable jack that includes a printed circuit board (PCB) for balancing both inductive and capacitive coupling. The method includes using two distinct inductance zones separated by a neutral zone. Significant gains in degrees of freedom are achieved for designing PCB trace patterns in which a pair of inductive coupling zones jointly offset the inductive coupling caused by a specification plug and the jack contacts, both in magnitude and phase angle. Further, using distinct inductance zones offers more freedom regarding the placement of capacitive plates for use in capacitance balancing as well as the placement of terminals and insulation displacement contacts. Although the magnitude of a capacitive coupling is determined by the length of the capacitor plates parallel to current carrying traces, the approach allows capacitive and inductive coupling to be balanced independently.
