Abstract

An unshielded telecommunications cable with a nominal characteristic impedance of 100 ohms and a core with a maximum of six pairs of individually insulated conductor wires. The wire insulation is a flame retardant polyolefin base compound and the conductors of each pair are twisted together with a maximum twist lay of 2.3 inches. The core is surrounded by a flame retardant jacket.
