  • Patent number: 9011181
    Abstract: A network cable jack includes a printed circuit board (PCB) for balancing both inductive and capacitive coupling. Using a PCB allows compact trace paths to be formed without significantly increasing manufacturing costs. By including on each trace path two distinct inductance zones separated by a neutral zone, significant gains in degrees of freedom are achieved for designing PCB trace patterns in which a pair of inductive coupling zones jointly offset the inductive coupling caused by a specification plug and the jack contacts, both in magnitude and phase angle. Further, using distinct inductance zones offers more freedom regarding the placement of capacitive plates for use in capacitance balancing as well as the placement of terminals and insulation displacement contacts. Although the magnitude of a capacitive coupling is determined by the length of the capacitor plates parallel to current carrying traces, the approach allows capacitive and inductive coupling to be balanced independently.

  • Patent number: 8931167
    Abstract: An electrical connector adapted to receive a mating plug utilizes low-profile jack terminal contacts that can flex in their PCB-anchored base portions, which are substantially parallel to the PCB. Any bend in the distal connecting portion or in the intermediate transition portion of each terminal contact is gradual and forms an obtuse angle, thus minimizing stress concentrations. The contacts preferably are arranged in two oppositely facing and interdigitating rows of four contacts each. In one embodiment, the terminal contacts are anchored to the PCB by a contact cradle that constrains the base portion of each terminal contact at two spaced anchoring locations, allowing the base portion to flex therebetween. In another embodiment, the base portions of the terminal contacts are embedded in at least one elastomeric member, which is fitted to the PCB.

  • Patent number: 8369513
    Abstract: The present invention relates to methods and systems for minimizing alien crosstalk between connectors. Specifically, the methods and systems relate to isolation and compensation techniques for minimizing alien crosstalk between connectors for use with high-speed data cabling. A frame can be configured to receive a number of connectors. Shield structures may be positioned to isolate at least a subset of the connectors from one another. The connectors can be positioned to move at least a subset of the connectors away from alignment with a common plane. A signal compensator may be configured to adjust a data signal to compensate for alien crosstalk. The connectors are configured to efficiently and accurately propagate high-speed data signals by, among other functions, minimizing alien crosstalk.

  • Patent number: 8357013
    Abstract: The present invention involves connectors for reducing Far-End Crosstalk (FEXT) through the use of novel polarity swapping to negate the cumulative effect of FEXT. Skew adjustment is used to improve the FEXT cancellation from polarity swapping. The polarity reversal location or locations among FEXT sources are optimized to achieve maximum FEXT cancellation. The novelty polarity swapping technique can be applied to a wide variety of connectors, such as mezzanine connectors, backplane connectors, and any other connectors that can benefit from FEXT reduction.

  • Patent number: 8357014
    Abstract: Methods and systems for providing crosstalk compensation in a jack are disclosed. According to one method, the crosstalk compensation is adapted to compensate for undesired crosstalk generated at a capacitive coupling located at a plug inserted within the jack. The method includes positioning a first capacitive coupling a first time delay away from the capacitive coupling of the plug, the first capacitive coupling having a greater magnitude and an opposite polarity as compared to the capacitive coupling of the plug. The method also includes positioning a second capacitive coupling at a second time delay from the first capacitive coupling, the second time delay corresponding to an average time delay that optimizes near end crosstalk. The second capacitive coupling has generally the same overall magnitude but an opposite polarity as compared to the first capacitive coupling, and includes two capacitive elements spaced at different time delays from the first capacitive coupling.

  • Patent number: 8342888
    Abstract: A high speed connector (106) with reduced crosstalk utilizes individual connector support frames (121, 122) that are assembled together to form a block of connector units (112). Each such unit supports a column of conductive terminals (113) in two spaced-apart columns. The columns have differential signal terminal pairs separated from each other by larger intervening ground shields that serve as ground terminals. The ground shields are arranged in alternating fashion within the pair of columns and they are closely spaced together so as to define within the pair of columns, a serpentine pattern of ground shields that cooperate to act as a single “pseudo” shield within each pair of columns. The ground shields are substantially larger in width (GW) than the differential signal terminal pairs (SPW) to provide more effective signal isolation.

  • Patent number: RE44961
    Abstract: A forward-reverse crosstalk compensation method is provided for compensating capacitance/inductance on a printed circuit board of a connector. The method includes a forward compensation process and a reverse compensation process. The forward compensation process compensates the unbalanced capacitance in the plug of the connector by using the parallel conductive lines or wires. The reverse compensation process can be used to compensate the unbalance capacitance/inductance caused by the forward compensations in the same pair combination of the connector. In both forward compensation and reverse compensation processes, electro-magnetic fields, such as capacitors, can be formed to balance the capacitance/inductance on the printed circuit board of the connector.
