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 which includes a housing with an aperture for receiving a communication plug, and a circuit board at least partially within the housing. The circuit board includes crosstalk compensation elements. A plurality of plug interface contacts are connected to the circuit board. At least one of the plurality of plug interface contacts includes a contact element layered with at least one spring element.

Abstract:
A field terminal plug assembly including an RJ45 plug connected to a termination zone. The termination zone includes a wire cap, a rear sled, and an electrical board assembly with attached insulation displacement contacts (IDCs) electrically connected to the twisted wire-pairs of assembly cable. The wire cap is configured to terminate twisted wire-pairs of a communications cable to the IDCs when the wire cap is inserted into the rear sled. The IDCs contain at least a first and a second IDC, the first IDC having a first horizontal length and a first vertical length and the second IDC having a second horizontal length and a second vertical length. The first vertical length does not equal the second vertical length but the first vertical length plus the first horizontal length equals the second vertical length plus the second horizontal length.
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.

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.
