The conductor of this 2 Pair Telephone Cable is 0.5 mm in diameter and is insulated with a special grade polyethylene compound on the latest state-of-the-art extruders. The cores are twisted together with a uniform layer on a special purpose imported machine, according to the color code to form pairs. The pairs are bunched together in such a manner so as to minimize cross-talk. The cable is then jacketed with a specially formulated PVC compound with fire retarding properties. A nylon rip cord provides an effective means of slitting the jacket without damaging the insulation. These are ideal because of low attenuation and low cross talk. Available in a standard pack of 90 Meters. Telephone cables sometimes also termed as Rj11 cables
