Cat6 Plenum Bulk Ethernet Cable 1000ft Black - 10Gbps Performance

Our review of the Cat6 Plenum Bulk Ethernet Cable 1000ft Black finds it best suited for IT installers and facility managers who need a long, code-compliant cable run for plenum spaces. The single biggest reason to buy is the combination of a CMP plenum jacket and pure 23AWG solid bare copper conductors, which deliver reliable signal and meet strict fire-safety requirements for air-handling spaces. In testing and field use this cable consistently supports multi-gigabit networking and Power over Ethernet, making it a dependable choice for structured cabling projects.

Key Features

• Extreme performance: Tested to 550MHz, it supports 1 and 5 Gigabit to 328ft and 10 Gigabit to 165ft for high-bandwidth connections.
• PoE capable: Supports PoE, PoE+, and PoE++ (4PPoE) up to 100W, so it can reliably power cameras, APs, and access devices over long runs.
• Plenum rated jacket: The CMP jacket meets plenum fire safety standards, offering high flame resistance and low-toxicity smoke for air plenum spaces.
• Pure copper conductors: 23AWG solid bare copper delivers better conductivity and flexibility than CCA alternatives for stable links.
• Jobsite friendly: Supplied on a tangle-free reel with footage markings every 2 ft to speed pull and measurement on installation.

Who It's For

This cable is aimed at electricians, network contractors, and IT teams installing cabling in commercial buildings, data centers, or homes where runs must pass through plenum air spaces and meet CMP code. The 1000ft spool and pre-spooled reel are convenient for long backbone runs or wiring multiple closets from a single feed.

Those who need runs beyond the 10Gbps reach (over 165 ft) for full 10Gig links should plan link layout accordingly, and hobbyists who do not require plenum rating or professional reels may find lower-cost non-plenum alternatives more economical.

Pros & Cons

Pros

• High bandwidth and tested performance to 550MHz for reliable multi-gigabit use.
• Plenum CMP jacket ensures compliance for air-handling spaces and better fire performance.
• Solid 23AWG bare copper provides consistent conductivity and compatibility with 23AWG RJ45 terminations.
• Pre-spooled reel and footage markings make pulls and inventory quick on site.

Cons

• At full 1000ft spool size the cable can be stiff to handle for some installers, so maneuvering in tight spaces may be challenging.
• More costly than non-plenum or CCA options, reflecting its safety rating and pure copper construction.

Our Verdict

For professional installers and facilities that require a plenum-rated Cat6 solution, this 1000 ft black spool represents good value because it pairs a CMP jacket with pure 23AWG copper and proven bandwidth performance. It is a practical, code-aware choice when you need long runs, PoE support, and consistent signal integrity, though those on a tight budget or not needing plenum compliance can find cheaper alternatives.
