Abstract: A cable organizer including an elongate body having two opposite ends, one called a cable receiving end and the other called a terminal receiving end, and a plurality of wire-receiving passages formed in the elongate body and separated from each other by electrically conductive portions in the body, each wire-receiving passage extending from the cable receiving end to the terminal receiving end and being open at both ends, each wire-receiving passage being adapted for guiding therethrough a plurality of wires of a multi-pair communication cable from the cable receiving end to the terminal receiving end, and being adapted for arranging a plurality of wires of a multi-pair communication cable at the terminal receiving end for connection with a modular plug. The wire receiving passages have parallel but not coplanar surface portions that are joined by an intermediate portion. This causes a different wire receiving passage cross-section at the cable-receiving end compared to the terminal-receiving end.
