Abstract
The present invention relates to an improved cable comprising a plurality of twisted pairs of conductors and a jacket in which the twisted pairs of conductors are located. The jacket defines an interior passage that extends along a length of the jacket, the interior passage including a central air region and a peripheral air region. The plurality of twisted pairs of conductors are positioned within the central air region. The peripheral air region of the interior passage includes a plurality of air channels that are circumferentially spaced relative to one another about the central air region of the interior passage. The channels are in fluid communication with the air in the central air region of the interior passage. Apparatuses and methods of manufacturing the improved cable are also disclosed.
