Category 3 Cable

Category 3 (Cat3) cables are reliable twisted-pair copper cables designed for voice communication, low-speed data transmission, and legacy networking systems. Commonly used in telephone systems, building automation, and control applications, Cat3 cables support frequencies up to 16 MHz and data rates up to 10 Mbps.

These cables are ideal for cost-effective installations where high bandwidth is not required, providing stable performance for voice, signaling, and basic data transmission in commercial and industrial environments.
