Abstract:
The present invention generally relates to the field of network communications, and more specifically to networks for crosstalk reduction/compensation and communication connectors which employ such networks. In an embodiment, the present invention is an RJ45 jack with an orthogonal. compensation network to meet CAT6A or higher performance standard. For the 3:6-4:5 wire-pair combination, the orthogonal compensation network begins in the jack nose (plug interface contact (PIC)) section, and utilizes a flexible printed circuit board in the nose section, split PIC contacts in the rear nose, and circuitry in the rigid printed circuit board to create the orthogonal compensation network.
Abstract:
A network cable jack includes a printed circuit board (PCB) for balancing both inductive and capacitive coupling. Using a PCB allows compact trace paths to be formed without significantly increasing manufacturing costs. By including on each trace path 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.
