摘要： A communication cable formed by cabling units such that each two adjacent units have different twist pitches, each unit including insulated wire pairs twisted together. A twist pitch P.sub.i of insulated wire pair T.sub.i selected among insulated wire pairs constituting a unit U.sub.i, and a twist pitch P.sub.j of insulated wire pair T.sub.j selected among insulated wire pairs constituting a unit U.sub.j, are different. Twist pitches P.sub.i and P.sub.j are selected from a region which satisfies expression (1) and either (2) or (3). Twist pitch P.sub.i and twist pitch P.sub.k of insulated wire pair T.sub.k selected among insulated wire pairs constituting a unit U.sub.k, are selected from a region which satisfies expression (4) where twist pitches P.sub.i and P.sub.k are in compliance with prior conditions given by (4).

摘要： A communication cable is provided that satisfies the requirement of Cat.6 for near-end cross talk wherein the difference between the maximum and minimum values of delay time among the four twisted wire pairs constituting the cable is within 25 ns/100 m. The communication cable is made by entwining four twisted wire pairs (T1), (T2), (T3), (T4) made by twisting pairs of insulated wires made by covering electrically conductive wires by polyolefin thermoplastic resin with each pair being twisted with a twist pitch different from the others (pitch: P1
