Black Box CAT6 400 MHz Shielded Plenum Cable, 1,000 ft

Deliver consistent Ethernet performance across structured cabling projects with a CAT6 bulk cable designed for enterprise environments. This shielded F/UTP cable helps reduce the impact of external noise and crosstalk, making it a practical fit for network rooms, ceiling plenum pathways, and other installations where signal integrity matters. The 400 MHz rating provides the performance margin expected from a higher-grade copper cable, supporting dependable connectivity for modern office and campus networks. The CMP plenum jacket is a key advantage for installations that must meet air-handling space requirements, allowing teams to standardize on a cable that fits both performance and compliance needs. Supplied on a 1,000 ft reel, it supports efficient deployment at scale and lets installers cut exact runs without excess slack. For organizations that want cleaner cable management, better environmental tolerance, and a more durable cabling foundation than basic unshielded options, this cable is built for the job.
