CAT6 Plenum Cable 1000FT - High-Performance 550MHz Ethernet

In this review the CAT6 Plenum Cable 1000FT is assessed for installers, small data centers, and offices that need a long run of fire-rated network cable. The single biggest reason to buy is its blend of plenum-rated safety and performance: 23 AWG, 4 twisted pairs and support up to 550MHz aim to handle Gigabit and 10-Gigabit Ethernet while meeting plenum fire codes. The cable comes on an easy pull 1000 ft box with sequential foot markings to speed installations and reduce waste, which is where it stands out in practical use.

Key Features

• 23 AWG 4-pair construction: Provides a stable conductor size and twisted-pair layout suited for Fast, Gigabit and 10-Gigabit Ethernet runs.
• 550MHz bandwidth: Supports higher frequencies than standard Cat6 expectations, helping maintain signal headroom on congested links.
• Plenum-rated jacket: The fire-retardant CMP jacket allows installation in air plenums above ceilings and below raised floors to meet building safety rules.
• Easy-pull 1000 ft box: Smooth dispensing and sequential foot markings make long runs faster to measure and reduce pull tangles on job sites.
• Center separator/spline: An integrated spline keeps pairs separated to lower crosstalk and preserve signal integrity over longer distances.
• Cost-effective CCA conductors: Copper-clad aluminum offers a budget-friendly conductor option for standard networking needs.

Who It's For

This cable suits network installers, contractors and IT teams that need a long, plenum-compliant Cat6 feed for ceilings or raised-floor plenum spaces where fire rating is required. The 1000 ft box and sequential markings are aimed at jobs that include long continuous runs, structured cabling backbones, and multi-outlet deployments.

Those seeking pure solid copper conductors for maximum conductivity or highest-end data center backbone links may want to consider solid pure-copper Cat6A or higher-spec cables; for typical office, classroom, or light data-center use where cost and plenum rating matter, this cable is a practical choice.

Pros & Cons

Pros

• Plenum-rated CMP jacket provides required fire safety for air-plenum installations.
• High-frequency support to 550MHz helps future-proof links for higher-speed traffic.
• Easy-pull box with sequential markings reduces install time and measurement errors.
• Center spline reduces crosstalk and helps maintain signal integrity on long runs.

Cons

• Uses copper-clad aluminum conductors, which are more budget focused and not as conductive as pure copper for very high-power PoE or mission-critical backbones.

Specifications

Cable type	Cat6 Plenum (CMP)

Our Verdict

The CAT6 Plenum 1000 ft cable is a good-value choice for regulated indoor runs where plenum-rated materials are required and long, continuous lengths are needed. It balances practical installer-friendly features like sequential markings and an easy-pull box with performance-oriented elements such as a center spline and 550MHz support; choose this if you need safety-compliant, economical Cat6 runs rather than the absolute best-conductivity pure-copper cable.

Frequently Asked Questions

Is this cable safe for use in plenum spaces?
Yes. The cable has a plenum-rated CMP jacket designed for air-plenum installations above ceilings or below raised floors.

Will this support 10-Gigabit Ethernet?
The cable is specified to support Fast, Gigabit and 10-Gigabit applications with bandwidth up to 550MHz, making it suitable for many 10GbE short runs depending on your equipment and distance.

Are the conductors pure copper?
The conductors are copper-clad aluminum (CCA), which is a cost-effective alternative to solid pure copper and suitable for standard networking installations but not identical in conductivity.
