A communication jack has a first pair and a second pair of contact wires defining corresponding signal paths in the jack. Parallel, co-planar free end portions of the wires are formed to connect electrically with a mating connector that introduces offending crosstalk to the signal paths. First free end portions of the first pair of contact wires are supported adjacent one another, and second free portions of the second pair are supported adjacent corresponding ones of the first free end portions. Intermediate sections of the first pair of contact wires diverge vertically and traverse one another to align adjacent to corresponding intermediate sections of the second pair of wires, to produce sufficient inductive compensation coupling to counter the offending crosstalk from the plug. Capacitive compensation coupling may be obtained for the contact wires via one or more printed wiring boards supported on or in the jack housing.

A scheme for compensating for both near-end (NEXT) and far-end (FEXT) crosstalk within a communication connector having first and second pairs of contact wires. A first stage of compensation includes capacitive coupling that corresponds in magnitude to a sum of offending capacitive and offending inductive crosstalk both of which originate from a mating connector. At a second stage of compensation, both (a) inductive coupling corresponding in magnitude to the offending inductive crosstalk, and (b) capacitive coupling corresponding in magnitude and of opposite polarity to the inductive coupling, are produced. In the disclosed embodiment, the first and the second compensation stages are implemented in an industry type RJ-45 communication jack to meet or surpass Category 6 NEXT/FEXT loss levels.

A communications jack includes: a dielectric mounting substrate; and a plurality of contact wires, each of the contact wires having a contact segment, a compensating segment in electrical connection with the contact segment, and a base in electrical connection with the compensating segment and mounted in the mounting substrate. The contact segments are generally transversely aligned and parallel with each other. The contact segments are arranged in pairs, with a first pair of contact segments being immediately adjacent each other, a second pair of contact segments being immediately adjacent each other and positioned one side of the first pair, a fourth pair of contact segments being immediately adjacent each other and positioned on an opposite side of the first pair, and a third pair of contact segments sandwiching the first pair, with one of the contact segments of the third pair being disposed between the first and second pairs, and the other of the contact segments being disposed between the first and fourth pairs. The compensating segments are configured and arranged such that differential to common mode crosstalk generated between the contact segments of the second and third pairs is opposite in polarity to the differential to common mode crosstalk generated between the compensating segments of the second and third pairs.

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.

A telecommunications connector includes first and second pairs of electrical conductors. The first and second pairs of conductors are arranged in one region of the connector such that one conductor of the first pair is selectively positioned to be closer to both of the conductors of the second pair than is the other conductor of the first pair, and such that the one conductor of the first pair couples a common mode signal of a first polarity onto the conductors of the second pair. In another region of the connector the other conductor of the first pair is selectively positioned to be closer to both of the conductors of the second pair to asymmetrically couple a common mode signal of a second polarity onto the conductors of the second pair.

A communications jack includes: a jack frame having a plug aperture; a plurality of contact wires, the contact wires having free ends that extend into the plug aperture, the free ends of the contact wires being arranged serially in side-by-side relationship; a plurality of electrical terminals, the terminals being arranged in pairs, each pair defining a communication channel; a dielectric mounting substrate, the mounting substrate including a plurality of mounting locations for contact wires and a plurality of mounting locations for the electrical terminals; and a plurality of conductors mounted on the substrate, each of the conductors extending, defining a path, and establishing electrical connection between a contact wire mounting location and an electrical terminal mounting location. First and second of the conductors that are connected to one of the pairs of terminals each include a coupling section, the coupling sections being immediately adjacent to each other and having identical instantaneous current direction such that the sections couple and cause a localized increase in inductance.
