Abstract

A high performance communications cable with core support-separators having various shaped profiles defining and maintaining a space between transmission multi-media or transmission multi-media pairs. The core may be of a conductive or insulative material. The central core region includes a hollow opening or duct for blown fiber (ABF). The core support-separator can be interior to the cable jacket or without the benefit of a jacket. A thin layer of material can act as a type of skin for future mechanical protection. The specially shaped core support-separator has a central region that is either solid, partially solid, foamed, with a solid skin over the foam or hollow itself. The cable may include a plurality of shaped sections that extend outward from the central region along the length of the central region. Each of the defined clearance channels allow for disposal therein of conductors and optical fibers.

Claims

1. A high performance communications cable comprising;

an interior support comprising an inner cross-like separator with rifled sections extending outward into four quadrants away from a central region, with quadrants defined by 90 degree right angles formed by an intersection of extended cross-like rifled separator sections encased within an outer insulated layer which is itself shaped in an identical cross-like pattern as said cross-like separator section so that dimensions of said outer insulated layer forms a cross-like pattern larger than said inner cross-like separator sections with rifled sections and functions as a skin for said inner cross-like separator section.

2. The high performance communications cable of claim 1, wherein said central region of said inner cross-like separator section with said outer insulated layer includes a hollow central region acting as a ductlet for an air blown fiber (ABF) which is available for filling with optical fiber or other conductors.

3. An interior support-separator for a communications cable comprising;

an interior support comprising an inner cross-like separator section with rifled sections extending outward into four quadrants away from a central region, with quadrants defined by 90 degree right angles formed by an intersection of extended cross-like rifled separator sections encased within an outer insulated layer which is itself shaped in an identical cross-like pattern as said cross-like separator section so that dimensions of said outer insulated layer forms a cross-like pattern larger than said inner cross-like separator sections with rifled sections and functions as a skin for said inner cross-like separator section.

4. The interior support-separator of claim 3, wherein said central region of said inner cross-like separator section with said outer insulated layer includes a hollow central region acting as a ductlet for an air blown fiber (ABF) which is available for filling with optical fiber or other conductors.
