Choosing the 20 Pair / 40 Core Unshielded Telephone Cable

20 pairs make it a riser or building backbone cable between the main frame and floor distribution boxes. No metallic screen keeps it light, flexible and quick to terminate; choose it for clean electrical environments where the route stays away from mains power and motor drives.

Order code: 40UR-TL. Send us the length, jacket and quantity for a project quotation and datasheet.

TMT Global 20 Pair / 40 Core Unshielded Telephone Cable Series

TMT Global 20 Pair / 40 Core Unshielded Telephone Cable is a configurable copper voice and low-speed communication cable family for telephone, PBX, intercom, analogue extension and building telecom distribution. The product page fixes the 20-pair unshielded twisted-pair construction, while the TMT Series ordering table provides exact conductor-size and jacket item codes for search, quotation and project selection.
