20100029104 | Pluggable cable connector - A pair manager for use in securing a twin-axial cable to a printed circuit board is described. The pair manager comprises a generally block-shaped portion containing a pair of channels. The channels extend from the front face to the rear face of the block-shaped portion. An integral flange and a pair of integral fingers extend perpendicularly from the front face of the block-shaped portion. The flange extends generally from the center of the front face and the fingers extend from opposite edges of the front face. The fingers and flange function as a partial shield cavity around each pair of conductors. This design helps to maintain better impedance matching when connecting twin-axial cables to a printed circuit board. | 02-04-2010 |
20100302754 | ACTIVE PATCH PANEL - An active patch panel uses small form factor plus (SFP+) connectivity with a plurality of channels extending between first and second faces of the panel. The channels connect ports on the opposing faces of the panel and are provided with additional electronic elements, such as an equalizer, a clock data recovery element, and a pre-emphasis element. A controller can be connected to the plurality of channels to provide instructions for simultaneous equalization and pre-emphasis of a plurality of cable assemblies in the same channel. | 12-02-2010 |

20120100744 | Communication Plug with Improved Crosstalk - A communication plug having a plug body and a plurality of contact pairs at least partially within the plug body, the contact pairs including an inherent asymmetric coupling between individual contacts of one of the contact pairs and other individual contacts of another of the contact pairs. Second asymmetric coupling elements are connected between the individual contacts of one of the contact pairs and the other individual contacts of another of the contact pairs. The second asymmetric coupling elements, when combined with the inherent asymmetric coupling, provide a balanced symmetric coupling between the individual contacts of one of the contact pairs and the other individual contacts of another of the contact pairs. | 04-26-2012 |
