Patent ID: 8546693

Claim:
A cable comprising: twisted pairs of insulated conductors, each twisted pair comprising two insulated conductors twisted together in a helical manner, the twisted pairs being grouped together to define a central core of the cable, the central core comprising a central longitudinal axis, the twisted pairs extending along helical paths around the central longitudinal axis in a first direction; a jacket at least partially surrounding the central core; an inner filler element wrapped helically around the twisted pairs of the central core between the central core and the jacket; and an outer filler element extending between the central core and the jacket, the outer filler element being wrapped helically around the twisted pairs of the central core and over the inner filler element such that the inner and outer filler elements create an air gap between the jacket and the central core, wherein the inner and outer filler elements are wound into winding turns that extend around the twisted pairs of the central core, and wherein the winding turns of at least one of the inner filler element or the outer filler element are wrapped around the twisted pairs in a second direction that is opposite the first direction.
