Abstract
In one embodiment, an apparatus includes a plurality of transformers and a plurality of common mode chokes, each of the transformers and the common mode chokes comprising a magnetic core and windings wound around the magnetic core at generally opposite sides thereof. The transformers and common mode chokes are arranged in an array with the windings on each of the magnetic cores positioned generally orthogonal to the windings of adjacent magnetic cores in the array to reduce crosstalk and improve common mode noise rejection.

An apparatus comprising:
- a plurality of transformers;
- and
- a plurality of common mode chokes, each of the transformers and the common mode chokes comprising a magnetic core and windings wound around the magnetic core at generally opposite sides thereof;
- wherein said plurality of transformers and said plurality of common mode chokes are arranged in an array with the windings on each of the magnetic cores positioned generally orthogonal to the windings of adjacent magnetic cores in the array to reduce crosstalk and improve common mode noise rejection.
An apparatus comprising:
- an array of transformers and common mode chokes each comprising a magnetic core and windings wound around the magnetic core at opposing locations on the magnetic core;
- and
- a retaining groove on each of the magnetic cores to maintain the windings in their opposing locations on the magnetic core;
- wherein the transformers and common mode chokes are positioned in the array with the windings on each of the magnetic cores located generally orthogonal to the windings of adjacent magnetic cores in the array to reduce crosstalk and improve common mode noise rejection.
An apparatus comprising:
- a connector for receiving a plurality of network communications cables, the connector comprising:
- a plurality of transformers;
- and
- a plurality of common mode chokes, each of the transformers and the common mode chokes comprising a magnetic core and windings wound around the magnetic core at generally opposite sides thereof;
- and
- a processor for processing data received from the connector;
- wherein said plurality of transformers and said plurality of common mode chokes are arranged in an array with the windings on each of the magnetic cores positioned generally orthogonal to the windings of adjacent magnetic cores to reduce electromagnetic interference in the array.
