Patent ID: 8525030

Claim:
A data transmission cable comprising: four or fewer twisted pairs of data transmission conductors, the four or fewer twisted pairs of data transmission conductors defining a core; and a jacket defining an interior passage that extends along a length of the jacket, the interior passage including a central region including air and a peripheral region, the four or fewer twisted pairs of data transmission conductors being positioned within the central region, the air in the central region occupying a volume between the four or fewer twisted pairs of conductors, the peripheral region of the interior passage including a plurality of channels that are circumferentially spaced relative to one another about the central region of the interior passage, the channels including air, the air in the channels being in fluid communication with the air in the volume of the central region between the four or fewer twisted pairs of data transmission conductors, the number of channels being greater than the number of twisted pairs of data transmission conductors, and a depth along a radial direction of each channel of the plurality of channels being greater than a diameter of each data transmission conductor of the four or fewer twisted pairs of data transmission conductors.
