Problems solved by technology

However, due to the time delay between the points at which the aggressor and compensating crosstalk signals are injected onto the victim differential pair, the signals will be phase shifted such that the aggressor and compensating crosstalk signals are not exactly 180 degrees apart in phase
The amount of this phase shift can become significant when using higher frequency signals, which reduces the effectiveness of crosstalk compensation

Embodiment Construction

[0069] According to embodiments of the present invention, there is provided a communication jack that can operate at very high frequencies (eg, 1-2 GHz or higher) while exhibiting good crosstalk cancellation and return loss performance.

[0070]In some embodiments, the communication jack includes a plurality of jack wire contacts electrically connected to the flexible printed circuit board. The socket wire contacts (also referred to herein as "leadframes") may be designed to reduce or minimize the amount of intrusive crosstalk generated within the leadframe. In general, the less offending crosstalk is produced, the better the outlet will perform, given the difficulty of completely canceling out this offending crosstalk. In some embodiments, the receptacle wire contacts may be arranged in a staggered manner such that the receptacle wire contacts are arranged in two or more lateral rows. This staggering can reduce the amount of offending crosstalk generated in the plug contact ...

Abstract

Communications jacks include a housing having a plug aperture that is configured to receive a mating RJ-45 plug along a longitudinal axis and eight jackwire contacts that are arranged as four differential pairs of jackwire contacts, each of the jackwire contacts including a plug contact region that extends into the plug aperture. A first of the jackwire contacts is configured to engage a longitudinally extending surface of a first blade of a mating RJ-45 plug when the mating RJ-45 plug is fully received within the plug aperture.

[0001] Cross References to Related Applications [0002] This application claims priority under 35 U.S.C. §119(e) to U.S. Provisional Patent Application 61 / 699,903, filed September 12, 2012, and U.S. Provisional Patent Application 61 / 697,955, filed September 7, 2012, incorporated by reference The entire disclosure of each of these is incorporated herein. technical field [0003] The present invention relates generally to communication connectors and more particularly to communication jacks. Background technique [0004] Computers, fax machines, printers, and other electronic devices are conventionally connected to network equipment (such as routers, switches, servers, etc.) by communication cables. FIG. 1 illustrates the manner in which a computer 10 may be connected to a network device 30 (eg, a network switch) using conventional communication plug / socket connections. As shown in FIG. 1 , a computer 10 is connected to a communication socket 20 installed in a wall socket p...
