COMMUNICATION CONNECTOR WITH INDUCTIVE COMPENSATION

摘要

A compensating jack connector includes a printed circuit (PC) board with wire trace layers for reducing unwanted crosstalk originating in wire pairs including those found within a conventional communication plug coupled to the compensating jack connector. Some embodiments of the PC board of the compensating jack connector include layers having inter-digitated capacitance to form compensative capacitive coupling and multi-point compensative coupling and inductance to form inductive coupling to reduce the unwanted crosstalk. Pairs of wire traces are so oriented in some of the PC board layers to couple inductance between one pair of wire traces with inductance between another pair of wire traces to contribute in reduction of unwanted crosstalk. Some embodiments of multi-point compensative coupling position inter-digitated capacitance at different time delay distances from origination points of unwanted crosstalk and having different polarities to contribute in reduction of unwanted crosstalk. Other embodiments of the PC board have layers that include other capacitive coupling having a single time delay distance from a source of unwanted crosstalk. Further embodiments of the PC board of the compensating jack connector include layers having combinations of the inductive compensative coupling, multi-point compensative coupling, and the other capacitive coupling.
