Abstract: 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.

Abstract: The present invention is directed to a system and method for reducing crosstalk caused by compensation schemes used in a connector to reduce crosstalk. The system provides for balancing crosstalk in an electrical connector having three or more pairs of conductors, wherein two pairs of conductors form a pair combination. The connector also has at least one compensating coupling device connected between conductor pairs of a first pair combination. The compensating coupling device disturbs the crosstalk balance of a second pair combination. The system for balancing crosstalk in the second pair combination includes a corrective coupling device that is connected between the conductor pairs of the second pair combination. In addition, compensating coupling devices in the second pair combination can be adjusted to counteract any crosstalk disturbances caused by the corrective coupling device.

Abstract: 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.

Abstract: An electrical connector (e.g., a plug or receptacle for a plug) has multiple conductors that carry two or more transmission paths, where each transmission path uses (at least) two conductors to carry a balanced signal. A portion of the like conductors of one type are grouped together and separated from a portion of like conductors of another type. For example, in one embodiment, the electrical connector is a plug having contacts used to terminate a multi-wire cable carrying up to four voice or data signal transmission paths and having four pairs of TIP-RING contacts, where a portion of the four TIP contacts are grouped together and a portion of the four RING contacts are grouped together and separated from the group of TIP contacts. In this way, electromagnetic (e.g., capacitive and/or inductive) coupling between like conductors (e.g., from TIP contact to TIP contact) will be generated that opposes electromagnetic coupling between unlike conductors (e.g.

Abstract: Crosstalk compensation is achieved by connecting coupling devices (e.g., capacitors) between different pairs of conductors of a multi-pair connector. The coupling devices are selected to offset both differential-to-differential coupling as well as differential-to-common-mode coupling that would otherwise occur between pairs of conductors when one of the conductor pair is driven with a differential signal. The present invention can be used to achieve both differential and common-mode crosstalk compensation without relying on conductor crossover techniques.

Abstract: Electrical connectors for electrically and physically connecting cable conductors to mating connectors frequently require precise and demanding assembly in order to produce a required level of crosstalk. In many instances, this level must be a set amount, rather than the lowest level possible, in order to match a canceling crosstalk being produced in the mating connector. The present invention is a crossover lead frame connector which reduces the demands upon the assembler in assembling the connector and cable, and yet still provides the precise level of crosstalk required in the connector. These advantages are realized by the use of a crossover lead frame structure which controls the physical length and routing of the signals between the cable conductors and connector pins. This allows the manufacturer to match the connector to the layout of the cable conductors and fix the level of crosstalk that will be produced at the time the connector is manufactured.

Abstract: Connectors, such as 110-type patch plugs, are designed to reduce near-end crosstalk that is generated when the connector is mated to a corresponding receptacle, such as a 110-type connecting block. Connectors of the present invention employ a two-stage crosstalk compensation scheme in which a first stage induces a compensating crosstalk signal, having opposite polarity as the original crosstalk signal, while the second stage induces a counter-balancing crosstalk signal, having same polarity as the original crosstalk signal. The two-stage, counter-balanced crosstalk compensation scheme of the present invention takes into account both the magnitude of the original crosstalk signal as well as the phase differences between the original crosstalk signal and the compensating and counter-balancing crosstalk signals that result from the different locations along the signal path at which the crosstalk signals are induced.

Abstract: Connectors, such as 110-type patch plugs, are designed to reduce near-end crosstalk that is generated between the twisted pairs of multi-wire cordage. Connectors of the present invention have a wire guide having a plurality of channels within which the different twisted pairs and ultimately the individual wires are distributed from the cordage to corresponding conducting contacts of the connectors. The channels of the wire guide enable improved control over the twist rates of the different twisted pairs as well as the routing paths between the cordage and the contacts which reduces the level of near-end crosstalk as well as variability in that level from one connector assembly to another. In one particular embodiment, the connector has a four-piece modular design (not counting the individual contacts) having separate wire guide, contact base, top cover, and bottom cover.
