Abstract

A connector plug terminates a communication cable having a plurality of twisted pair conductors therein. The plug includes a conductor organizing sled, which includes structural features to minimize variations in conductor organization, as the conductors pass along the sled. By minimizing the variations as the conductors pass along the sled, technicians may assemble plugs having a relatively consistent level of crosstalk. The structural features of the organizing sled may include combinations of a ramp surface for a center pair, neck-down portions to cause consistent placement of stacked pairs, and crossing of stacked pairs to prevent a lower stacked pair from rising above a floor surface of the sled.
