High performance data cable and a UL 910 plenum non-fluorinated jacket high performance data cable

A UL 910 plenum high performance data cable comprising a cable core containing at least four twisted pair cables, each of the said twisted pair cables being laterally shielded and bound to provide at least four bound lateral shielded twisted pair cables,

• a temperature-resistant flame retardant separator tape surrounds the at least four bound lateral shielded twisted pair cables, said separator tape being between said jacket and a cable core, and
• said jacket is a non-fluorinated polyolefin
• wherein said separator tape is wrapped around the twisted pair at a tension to eliminate a substantial amount of the air and to leave a cross sectional void area of less than 25% of the cross sectional area of the shielded twisted pair cables to provide the bound lateral shielded twisted pair cable and
• to provide the bound lateral shielded twisted pair cable with an adjusted 20° C. standard impedance deviation of 4.5 or less when said standard deviation is calculated around a mean or average impedance of 50 to 200 ohms.

A method of preparing an individual bound lateral twisted pair data cable comprising:

• providing a twisted pair cable having an insulation selected from the group consisting of foamed or non-foamed fluorocopolymer and polyolefin;
• laterally wrapping said twisted pair cable with a metal shielding tape to provide a lateral shielded twisted pair cable with at least a 10% overlap of said shielding tape and said shielding tape having a metal thickness of 0.33 to 2.00 mils, and said shielding tape being selected from the group consisting of a metal tape, a first composite tape having a non-metal base and a layer of metal on one side of said base, and a second composite tape having a non-metal base and a layer of metal on both sides of said base;
• wrapping said lateral shielded twisted pair cable with a fabric or metal binder to provide a bound lateral shielded twisted pair cable;
• and
• wrapping the lateral metal shield and binder at a tension to provide said bound lateral shielded twisted pair cable with an adjusted to 20° C. standard impedance deviation of 4.5 or less when said standard impedance deviation is measured on a 328 ft. or longer cable with at least 350 frequency measurements being taken and the standard impedance being calculated around a mean or average impedance of 50 to 200 ohms.
