More information
Product Introduction
A cable made up of multiple pairs of insulated copper wires —typically twisted together—, used to transmit low-frequency telephone and data signals.
Features
Color-coded insulated twisted-pair construction, offering a high number of pairs (e.g., from 10 to over 200) and designed to reduce crosstalk and external interference in voice transmission.
Applications
It is used in telephone switching rooms and distribution boards to connect the central office's switching equipment to multiple subscriber lines, enabling the distribution of voice services on a large scale.
