Etrolink NW-CAT3 Outdoor Voice/Data Cable (Black) – 500M
The Etrolink NW-CAT3 Outdoor is a ruggedized multipair cable specifically engineered for telecommunications and low-speed data applications. Designed to withstand the elements, this 500-meter bulk roll is the standard choice for professional outdoor voice networking, intercom systems, and telephone line extensions.

Key Features
Weatherproof Outdoor Jacket: Features a heavy-duty, UV-resistant Black PE (Polyethylene) jacket. This specialized outer layer protects the internal pairs from sun damage, moisture, and temperature fluctuations, preventing the cracking common in standard indoor cables.

Massive 500M Length: The extended spool length is ideal for large-scale campus deployments, connecting multiple buildings, or long-distance perimeter intercom installations without the need for signal-degrading joins.

High-Quality Twisted Pairs: Designed to minimize crosstalk, ensuring clear voice communication and reliable low-frequency data transmission.

Tension Resistance: Built with a higher tensile strength than indoor variants to handle the physical stress of being pulled through outdoor conduits or secured along exterior walls.
