Abstract
We provide a high performance bound lateral shielded twisted pair cables, a high performance data cable containing at least four of the bound lateral shielded twisted pair cables, and a method for preparing the same. The bound lateral shielded twisted pair cables preferably have a 20° C. adjusted standard impedance deviation of 4.5 or less and the high performance data cable contains at least four of the bound lateral shielded twisted pair cables and has a 20° C. adjusted average standard impedance deviation of 4.5 or less. The twisted pair is laterally wrapped with a metal shield tape and a fabric or metal braid or thread at a tension that provides the above. The tension is such that it provides a cross-sectional void area of less than 25% and preferably less than 18% of the lateral shielded twisted pair cable cross-sectional area. The tape is laterally wrapped with an overlap of at least 10% . Preferably, the cables have a rating out to 600 MHz and 1000 MHz. We also provide a UL 910 plenum at least category 5 high-performance data cable that has a non-fluorinated jacket and between the jacket and cable core, a temperature-resistant flame-retardant separator tape.
