Abstract: A testing unit including a substrate, a plurality of vias located in the substrate, a plurality of pin traces having a height and a width and each extending from a respective via towards an edge of the substrate, a plurality of end traces having a height and a width with each end trace extending from an end of a respective pin trace towards the edge of the substrate, a plurality of branch traces having a height and a width and each extending from a side of a respective pin trace, a plurality of traces extending from the end of a respective end trace, branch trace or pin trace to the edge of the substrate, where each end trace is adjacent to a respective branch trace, each end trace is adjacent to a respective branch trace on one side and a pin trace on the opposite side, and each pin trace is adjacent to another pin trace on one side.

Abstract: A method and apparatus provide for a physically small, simple, and inexpensive securing of a conventional RJ45 or similar plug into a conventional jack. A tab lock is configured to slide forward and backward along the plug, wherein when the tab lock is slid forward, a distally extending tongue reaches underneath a release lever to hinder the bending of the release lever. In this way a latch coupled to the release lever is prevented from un-latching with a corresponding latch in the jack. When the tab lock slides backward the tongue is removed from underneath the release lever and the plug may be removed from the jack. The tab lock further provides for visual identification of a particular plug.

Abstract: A high speed communication jack including a housing including a port for accepting a plug, the port including a plurality of pins each connected to a corresponding signal line in the plug and a shielding case surrounding the housing. A flexible circuit board between the shielding case and the housing having a substrate, a plurality of vias extending through the substrate with each via being configured to accommodate a pin on the housing, a plurality of traces on a first side of the substrate, with each trace extending from a corresponding one of the plurality of vias, and a shielding plane on a second side of the substrate opposite the first side of the substrate.
