Patent ID: 8344255

Claim:
A cable comprising: a core including a plurality of twisted pairs, each twisted pair including first and second insulated conductors twisted about one another, the core defining a central axis; a jacket including a main wall that surrounds the core, the main wall defining a generally circular configuration when the cable is viewed at a transverse cross-section, the main wall including an inner surface and an outer surface, the jacket also including four spacers integrally formed with the main wall and angularly spaced by about 90 degrees from one another about the central axis, each spacer extending helically about the central axis, each spacer including an inner projection that projects radially inwardly from the inner surface of the main wall toward the central axis, the inner projection spacing the core from the inner surface of the main wall such that an air gap is defined between the core and the inner surface of the main wall, each spacer also including an outer projection that projects radially outwardly from the outer surface of the main wall away from the central axis, wherein the inner projection of each spacer is generally radially aligned with the corresponding outer projection of each spacer when the cable is viewed at the transverse cross-section.
