More information
Product Introduction
Multipair telecommunications cable designed to transmit multiple voice channels or analog signals over short or medium distances.
Features
Low crosstalk between pairs, typical impedance of 100 to 150 ohms, suitable for voice-grade frequencies (up to 1 MHz) and low-speed data (e.g., RS-485, analog telephony).
Applications
It is used in emergency call systems for elevators, intercom networks, RS-485 control links, and legacy data trunks where multiple independent circuits are required.
