Abstract:
A device for reducing crosstalk in a connector, the device being adapted to be mated with the connector and comprising:an insulating board having one or more layers;a first set of two or more pairs of conductive paths formed on a first surface of one of the layers;a second set of one or more pairs of conductive paths vertically spaced from the first set, wherein:each pair of conductive paths in the first and second sets comprises a conductive path of a first type T and a conductive path of a second type R;the first set comprises a first pair of conductive paths T.sub.1, R.sub.1, and a third pair of conductive paths T.sub.3, R.sub.3 ;the second set comprises a second pair of conductive paths T.sub.2, R.sub.2 ;the first pair is adjacent to the third pair;portions of two conductive paths P.sub.i and P.sub.j are said to be co-aligned when the conductive paths P.sub.i and P.sub.j lie on different mutually parallel surfaces and a projection, perpendicular to the mutually parallel surfaces, of a portion of the conductive path P.sub.i coincides with and is parallel to a portion of the conductive path P.sub.j ;a first portion of the conductive path R.sub.2 is co-aligned with a second portion of the conductive path T.sub.3 in order to contribute to a first type of compensating coupling having polarity opposite that of crosstalk generated in the connector between like conductors;a second portion of the conductive path R.sub.2 is co-aligned with a portion of the conductive path T.sub.1 in order to contribute to the first type of compensating coupling;a second portion of the conductive path T.sub.2 is co-aligned with a first portion of the conductive path R.sub.3 in order to contribute to the first type of compensating coupling; anda third portion of the conductive path T.sub.2 is co-aligned with a portion of the conductive path R.sub.1 in order to contribute to the first type of compensating coupling.
