Black Box Cat 6 1000 ft bulk cable

The Black Box EYN872A-PB-1000 is a 1000 ft yellow Cat 6 bulk cable designed for structured wiring projects. Installers pull it through walls and ceilings to create permanent network runs. It terminates on patch panels or keystone jacks at each end. The solid conductors suit fixed installations rather than flexible patch cords.

Sustained 550 MHz bandwidth for long runs

Rated at 550 MHz, the cable supports Gigabit Ethernet and 155-Mbps ATM over the full 1000 ft length. It meets ANSI/TIA/EIA-568-B.2-1 Category 6 and ISO/IEC 11801 Class E requirements, so signal integrity holds on extended horizontal runs. The unshielded design relies on pair twist geometry to control crosstalk without a drain wire.

Bare wire ends need termination tools

Both ends arrive as bare wire, requiring a punch-down tool and compatible Cat 6 jacks or patch panels. The CMR grade PVC jacket is rated for riser spaces but not for plenum air handling areas. Solid conductors can fracture if bent repeatedly, so avoid tight service loops or frequent re-termination. Verify local fire codes before routing through vertical shafts.
