Datacommunications modules, cable-connector assemblies and components therefor

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.

Next high frequency improvement by using frequency dependent effective capacitance

Communications jacks include a housing having a plug aperture that is configured to receive a mating plug that is inserted along a horizontal plug axis and a vertically-oriented wiring board that is mounted substantially normal to the horizontal plug axis. First through fourth contact wires are mounted in the vertically-oriented wiring board, with the first and second contact wires forming a first differential pair of contact wires and the third and fourth contact wires forming a second differential pair of contact wires. At least a portion of the first differential pair of contact wires is positioned between the contact wires of the second differential pair of contact wires, and deflectable portions of the third and fourth contact wires include a crossover. Additionally, the fixed portions of the third and fourth contacts are spaced further apart vertically than are the fixed portions of the first and second contacts.

Communications jacks having contact wire configurations that provide crosstalk compensation

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.

Communications jack with printed wiring board having paired coupling conductors

A communications plug includes: a mounting substrate; a plurality of pairs of output terminals attached to the mounting substrate; and first, second, third and fourth pairs of conductors. The first, second and fourth pairs of the output terminals are arranged in immediately adjacent relationship, and a third pair of output terminals includes output terminals that are separated from each other such that a first output terminal of the third pair is positioned between the first and second pairs of output terminals, and such that a second output terminal of the third pair is positioned between the first and fourth pairs of output terminals. Each of the first, second, third and fourth pairs of conductors is attached for electrical communication with a respective one of the output terminals. The third pair of conductors has at least two locations in which the conductors of the pair cross each other, and is arranged such that, between the crossover locations, the third pair of conductors forms an expanded loop that brings segments of the third conductor into closer proximity to the second and fourth pairs of conductors than to the first pair of conductors.

Communication plug with balanced wiring to reduce differential to common mode crosstalk

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.

Controlled mode conversion connector for reduced alien crosstalk

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.

Communications connector with leadframe contact wires that compensate differential to common mode crosstalk

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.

Simultaneous near-end and far-end crosstalk compensation in a communication connector

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.

Inductive crosstalk compensation in a communication connector

A communication connector assembly has a terminal housing, and a number of electrically conductive connector assembly terminals supported by the housing. The connector assembly terminals have first terminal portions extending from the housing for contacting terminals of a mating connector, and second terminal portions for making electrical connections with outside circuits. An electrical circuit component is disposed adjacent the terminal housing. The component is connected to a contact portion on at least one of the assembly terminals, intermediate a free end of the first terminal portion and the second terminal portion of the assembly terminal. The mating connector is thus connected to the electrical circuit component through the first terminal portions of the assembly terminals, in proximity to the circuit component. The electrical circuit component may be constructed and arranged to compensate for cross talk induced when the mating connector contacts the first terminal portions of the assembly terminals.
