Abstract: An isolation transformer includes a transformer core. First and second through-bores extend through the transformer core from a first surface to a second surface. Each through-bore has an elongated profile with at least a portion of the elongated profile providing a respective flat winding surface. The flat winding surfaces are spaced apart by a central portion of the transformer core. The transformer is wound with a six-wire cable having a central non-conductive core. First, second, third, fourth, fifth and sixth conductive wires are positioned around and adjacent to the central non-conductive core in a substantially equally spaced angular relationship. The second conductive wire is positioned between the first conductive wire and the third conductive wire; and the fifth conductive wire is positioned between the fourth conductive wire and the sixth conductive wire. The conductive wires are twisted about the central non-conductive core at a selected twist density.

Abstract: A multiport connector which includes a housing having at least two aligned compartments, each compartment being structured and arranged to receive respective plugs. A multilayer printed wiring board separates the two compartments, the printed wiring board having circuit patterns on opposite sides of opposed non-conductive layers and a metal shielding layer intermediate the non-conductive layers. A first plurality of conductive contact fingers is disposed in one of the compartments, the first plurality of fingers having first portions for making electrical contact with one of the plugs and second portions for making contact with the circuit pattern on one of the non-conductive layers of the multilayer printed wiring board.

Abstract: An RJ-45 jack having a groove to accommodate the width of an RJ-11 plug to allow the plug to rise upward and away from the outer contacts of the RJ-45 contacts upon inadvertent insertion of an RJ-11 plug into the RJ-45 jack.
