Abstract:
A connector is provided for simultaneously improving both the NEXT high frequency performance when low crosstalk plugs are used and the NEXT low frequency performance when high crosstalk plugs are used. The connector includes a first compensation structure provided on an inner metalized layer of the PCB at a first stage area of the PCB, and a second compensation structure, provided at a second stage area of the PCB, for increasing compensation capacitance with increasing frequency.
Abstract:
A connector is provided for compensating crosstalk with respect to an adjacently placed connector. Each of the connectors includes a printed circuit board (PCB), a plurality of pairs of contacts on the PCB, a plurality of pads disposed at edge portions of the PCB for compensating crosstalk, and a plurality of connecting parts for connecting electrically the pads to the pairs of contacts.

Abstract:
A communications jack assembly includes: a jack frame having a plug aperture; a dielectric mounting substrate attached to the jack frame; and a plurality of conductors engaged with the mounting substrate, each of the conductors including a fixed end portion mounted with the mounting substrate and a free end portion extending into the plug aperture for electrical contact with a mating plug, each of the free end portions having substantially the same profile and being substantially transversely aligned in side-by-side relationship. A first pair of conductors is sandwiched inside a second pair of conductors. The second pair of conductors includes a crossover, the positioning of crossover being selected to provide differential to common mode crosstalk compensation.
Abstract:
A communications connector includes: a dielectric mounting substrate; a plurality of conductors mounted in the mounting substrate; and a wiring board. Each of the conductors includes a fixed end portion mounted in the mounting substrate and a free end portion, each of the free end portions being positioned in side-by-side and generally parallel relationship, and each of the fixed end portions being positioned in side-by side and generally parallel relationship. The wiring board is positioned between the fixed and free end portions of the conductors, the wiring board being generally perpendicular to the conductors, the wiring board including first and second conductive traces that are electrically insulated from each other. First and second conductors are electrically connected with the first and second traces. The first and second conductive traces are arranged on the wiring board to create a crossover between the first and second conductors.

Abstract:
An insulation displacement contact (IDC) includes: upper and lower ends, each of the upper and lower ends including a slot configured to receive a conductor therein, the slots being generally parallel and non-collinear; and a transitional area merging with the upper and lower ends. An IDC of this configuration can be employed, for example, in 110-style connectors, and can enable such connectors to compensate for differential to common mode crosstalk between adjacent IDC pairs.
