Black Box ELN25TA-1000 CAT3 Telco Bulk Cable
Overview
The Black Box ELN25TA-1000 is a Category 3 bulk cable designed for voice applications and low-speed data networking. Its solid, unshielde construction ensures reliable performance for traditional telephone systems and basic data transmission where high bandwidth is not a requirement. This cable is suitable for installations within structured cabling systems in commercial buildings or data centers that still support legacy voice infrastructure.
Compatibility
This Category 3 cable is compatible with standard RJ11 and RJ45 connectors for voice and low-speed data applications. It is designed for use with PBX systems, VoIP phones, and basic network switches that do not require Category 5e or higher performance. Ensure your termination tools and connectors are rated for solid conductor Category 3 cable.
Installation Notes
The ELN25TA-1000 features solid conductors, which offer better performance over longer distances compared to stranded conductors but are less flexible. Avoid sharp bends or kinks during installation, as this can compromise signal integrity. Maintain a minimum bend radius of 4 times the cable diameter to prevent damage. The cable is black in color for easy identification within cable bundles.
