Abstract:
An electrical connector has a first shell, an opposing second shell and a circuit board between the first shell and the second shell. The circuit board has a first side and an opposing second side and includes a plurality of differential pair conductive traces on each side. A first drain wire termination device is provided on the first side and includes at least one separator between at least one of the differential pair conductive traces on the first side and another of the differential pair conductive traces on the first side. A second drain wire termination device is connected to the second side and includes at least one separator between at least one of the differential pair conductive traces on the second side and another of the differential pair conductive traces on the second side.
Abstract:
A communication connector is described that includes a plug and a jack, into which the plug is inserted. The plug terminates a length of twisted pair cable. The jack includes a sled to support contacts for connecting to wires within the cable, a rigid circuit board that connects to the contacts, and a flex board that contacts the plug interface contacts. The jack also includes circuitry to compensate for crosstalk between wire pairs of the cable by adding capacitance values within the sled, rigid circuit board and/or flex board between traces carrying signals from the wire pairs so that crosstalk caused by the plug between wire pairs that have signals in phase cancels with crosstalk caused by the plug between signals out of phase, and so that the capacitance values added between each trace are about equal. The compensation is performed to reduce differential to common mode signal conversion.

Abstract:
A communication Jack has a housing with a face having a plug receiving aperture. A conductive path pairs extends from corresponding plug interface contacts located at the plug receiving aperture to corresponding output terminate. A first circuit board is connected to the plug interface contacts and a second circuit board is connected to the plug Interface contacts and the output terminals. The first circuit board has a first single stage of crosstalk compensation with opposite polarity of the crosstalk of a plug for a first combination of the conductive path pairs. The second circuit board includes a second single stage of opposite polarity crosstalk compensation for some of the conductive path pairs not compensated on the first circuit board. The stages cancel substantially ail of the crosstalk caused by the plug, for the signal operating frequencies, for corresponding combinations of the conductive path pairs.
Abstract:
A communication connector uses compensation circuitry to compensate for crosstalk in a network connection. Capacitors are connected between specific conducive paths in said communication connector. Inductive stubs are utilized in the compensation circuitry to improve the overall compensation performance.

Abstract:
This application describes a jack for improving crosstalk attenuation. The jack has a housing, a foil at least partially surrounding the housing, a printed circuit board, and at least one pair of insulation displacement contacts and vias. Each pair of insulation contacts and vias are associated with a differential signal. A conductive trace stub is routed on the printed circuit board near the edge of the board in order to at least partially balance the coupling from one of the insulation displacement contacts and vias of a pair to the foil with the other insulation displacement contact and via of the pair.

A communication connector uses compensation circuitry to compensate for crosstalk in a network connection. Portions of the compensation circuitry are placed on a flexible circuit board that makes conductive contact with plug interface contacts of the connector. Additional compensation circuitry is provided on a rigid circuit board within the connector.
