Abstract
Abstract Disclosed is an electrical connector which compensates for near-end crosstalk at its mating section with near-end crosstalk of an opposite polarity and essentially equal magnitude. Conductive plates connected to the conductors provide capacitive coupling unbalance between the adjacent pairs to produce the necessary opposite polarity, equal magnitude near-end crosstalk.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
179 words
A connector comprising: a plurality of pairs of first and second conductors arranged in vertically spaced rows, each pair including a mating section adapted for connecting to another connector so that the first and second conductors receive signals of opposite polarities, the first and second conductors in each pair being in spaced vertical alignment, and the first conductors in each pair being in horizontal alignment with first conductors in adjacent pairs and the second conductors in each pair being in horizontal alignment with second conductors in adjacent pairs, so that the mating section produces near-end crosstalk of a first polarity and first magnitude when signals are applied thereto; conductive plates extending vertically from at least one conductor in at least selected pairs, the plate of a first conductor being spaced from the plate of a second conductor in an adjacent pair to provide capacitive coupling therebetween causing capacitive coupling unbalance between the two pairs when a signal is applied thereto in order to produce near-end crosstalk of a polarity which is opposite to that produced by the mating section.
Claim 2
Dependent Claim
179 words

Claim 3
Dependent Claim
23 words
The connector according to claim 1 wherein the opposite polarity crosstalk has a second magnitude which is essentially equal to the first magnitude.
Claim 4
Dependent Claim
34 words
The connector according to claim 1 wherein the plate of the first conductor is also spaced from a plate of a second conductor in a next adjacent pair to also provide capacitive coupling therebetween.
Claim 5
Dependent Claim
15 words
The connector according to claim 1 wherein the plates are integral parts of the conductors.
Claim 6
Dependent Claim
22 words
The connector according to claim 1 wherein the conductors further include a section for mounting the conductors to a printed circuit board.
Claim 7
Dependent Claim
29 words
The connector according to claim 1 wherein the connector further comprises a housing, and each conductor pair comprises a separate encapsulated module mounted within an aperture in the housing.
Claim 8
Dependent Claim
204 words
A connector comprising: a plurality of pairs of first and second conductors arranged in a row, each pair including a mating section adapted for connecting to another connector so that the first and second conductors receive signals of opposite polarities, the first and second conductors in each pair being in spaced vertical alignment, and the first conductors in each pair being in horizontal alignment with first conductors in adjacent pairs and the second conductors in each pair being in horizontal alignment with second conductors in adjacent pairs, so that the mating section produces near-end crosstalk of a first polarity and first magnitude when signals are applied thereto; conductive plates extending vertically from at least one conductor in at least selected pairs, the plate of a first conductor being spaced from the plate of a second conductor in an adjacent pair to provide capacitive coupling therebetween causing capacitive coupling unbalance between the two pairs when a signal is applied thereto in order to produce near-end crosstalk of a polarity which is opposite to that produced by the mating section, wherein the conductive plates in each pair extend vertically past the conductors and the plates extend more past alternate ones of the conductors in alternate pairs.
Claim 9
Dependent Claim
204 words
