Abstract
The present invention includes a high performance communications cable exhibiting reduced cross-talk between transmission media that includes one or more core support separators (122) having various shaped profiles which define a clearance to maintain a spacing between transmission media or transmission media pairs. The core may be formed of a conductive or insulative material to further reduce cross-talk. The central core region may include a hollow opening or duct for blown fiber (ABF). The specially shaped core support-separator can be either interior to the cable jacket or be employed singularly without the benefit of a jacket, then a portion of the separator wherein a thin layer of material can act as a type of skin for future mechanical protection may exist. The cable may include a plurality of shaped sections that extend outward from the central region and that define distinct clearance channels for disposal therein of conductors and/or optical fibers.
