摘要:
Patch cords include a communications cable that has first through eighth conductors that are arranged as four twisted pairs and a plug attached thereto. The plug includes a housing that receives the cable, first through eighth plug contacts, and a printed circuit board that includes first through eighth conductive paths that connect the first through eighth conductors to the respective first through eighth plug contacts. The plug further includes a first crosstalk injection circuit between the second conductive path and the sixth conductive path and a second crosstalk injection circuit between the first conductive path and the sixth conductive path.
摘要:
Communications plugs are provided which include a printed circuit board having a plurality of elongated conductive traces and a plurality of plug blades. Each plug blade has a first section that extends along a top surface of the printed circuit board and a second section that extends along a front edge of the printed circuit board. Additionally, each plug blade may have a thickness that is at least twice the thickness of the elongated conductive traces. The plug blades may be low profile plug blades that are manufactured separately from the printed circuit board.

摘要:
Communications plugs are provided that include a housing that receives the conductors of the communication cable. A printed circuit board is mounted at least partially within the housing. A plurality of plug contacts are on the printed circuit board, and the printed circuit board includes a plurality of conductive paths that electrically connect respective ones of the conductors to respective ones of the plug contacts. First and second of the conductive paths are arranged as a first differential pair of conductive paths that comprise a portion of a first differential transmission line through the communications plug, where the first differential transmission line includes a first transition region where the impedance of the first differential transmission line changes by at least 20% and a second transition region impedance of the first differential transmission line changes by at least 20%.
