Black Box Corporation

Black Box 1000ft Cat.6 STP Bulk Network Ethernet Cable EVNSL0605A1000

SKU CH-6577-WYPSN

Shielded Cat.6 bulk cable on a 1000ft spool, rated to 400 MHz and compliant with TIA/EIA-568-B.2-1 and ISO/IEC 11801

  • Shielded construction reduces interference for reliable data transfer
  • Cat.6 rating supports 400 MHz bandwidth for high-speed networks
  • Solid bare copper conductors ensure consistent signal quality
  • UL 444 compliance confirms safety and performance standards
  • 1000 ft spool provides ample length for large installations

Black Box Cat.6 STP 1000ft Bulk Cable

This 1000-foot spool of Category 6 shielded twisted-pair cable is built for permanent indoor installations. It meets TIA/EIA-568-B.2-1 and ISO/IEC 11801 standards with a verified 400 MHz bandwidth. The solid bare conductors are designed for punch-down termination on patch panels and keystone jacks. Supplied new on a pull-box spool for easier cable management.

Suited for structured-wiring runs needing

Installers pulling horizontal links through walls, ceilings or conduit will appreciate the foil shield and UL 444 listing. Projects that require stranded patch cables, pre-terminated assemblies or outdoor-rated jackets should look at a different product type. The solid-core construction is not intended for repeated flexing or direct equipment connections.

400 MHz tested bandwidth defines the link ceiling

This single figure determines whether the cable supports the desired application class. If the design calls for higher-frequency operation, this spool will not meet the requirement. All other specifications reference the same Category 6 baseline.

Questions about this item

How do I install the 1000 ft Cat.6 STP bulk cable from the spool and what step is often missed?

Pull the solid-conductor cable from the 1000 ft spool, maintain the pair twist close to each termination, and ground the foil shield at both ends.

What maintenance or replacement will this shielded Cat.6 bulk cable need later?

Inspect the foil shield and drain wire for damage after any pulling or bending, and replace the run if the shield continuity is broken.

What limit appears first under sustained use of this 400 MHz Cat.6 STP cable?

The 400 MHz bandwidth ceiling is reached before the TIA/EIA-568-B.2-1 Category 6 channel limit under continuous high-frequency loads.
