More information
Product Introduction
A multi-pair telephone cable is a single cable containing multiple pairs of individually insulated copper wires, designed for the efficient transmission of multiple telephone or data signals over a single consolidated line.
Features
Focused on physical and electrical specifications.
It contains multiple twisted pairs of copper conductors, individually insulated and color-coded.
It features a high number of pairs (e.g., 25, 50, 100 pairs) within a single compact protective cover.
It provides effective crosstalk suppression and signal integrity thanks to the precise twisting of the pairs.
It offers a balanced impedance (typically 100 Ω) for clear transmission of analog or digital voice/data.
Applications
It focuses on its traditional and fundamental functions in telephone networks.
It is mainly used as the main trunk cable in buildings, connecting the telecommunications provider's entry point (MDF) to the internal distribution panels.
It is essential for multi-line business telephone systems (PBX), providing connectivity for numerous desktop phones and fax machines.
It serves as the main vertical cable in multi-story buildings, distributing voice services between different floors from a central point.
