ASTEL Indoor Shielded Cat3 Telephone Cable (FTP-CAT3-BC-XX-PVC) is designed for indoor voice communication and structured telephone distribution networks. Available in 10, 20, 30, 50 and 100-pair configurations, it features 24 AWG solid bare copper conductors, HDPE insulation, aluminium foil shielding and a black PVC outer jacket. The cable supports Category 3 applications across a frequency range of 1–16 MHz with 100 ± 15 Ohm characteristic impedance. Its shielded multipair construction helps reduce electromagnetic interference, making it suitable for telephone distribution, ISDN, 10BASE-T and legacy data communication systems in commercial buildings, offices and residential complexes.
Two insulated wires twisted together. The twist length specially esigned to minimize the capacitance unbalance and cross talk.
