The best plenum-rated Cat6 cable depends on installation location, conductor material, cable length, and PoE needs. For dependable plenum-space wiring, the trueCABLE and MONK CABLES pure-copper CMP options offer the clearest match to the request. The MONK CABLES 1000-foot option listing a plenum rating uses copper-clad aluminum, while two Brozzag listings describe CMR riser cable—not plenum cable—so verify the jacket marking before buying for a plenum space.
| Product | Best suited for | Key detail |
|---|---|---|
| trueCABLE Cat6 Plenum CMP | PoE and longer runs | Solid bare copper; PoE++ support stated |
| MONK CABLES Pure Copper CMP | Bulk structured cabling | 1000 feet; 23 AWG bare copper |
| MONK CABLES Cat6 Plenum | Budget-conscious bulk projects | 1000 feet; verify conductor and jacket details |
| Brozzag 1000ft listing | Short, budget-oriented runs | Features specify CMR, not CMP |
| Brozzag 300ft listing | Smaller cable projects | Features specify CMR, not CMP |
trueCABLE Cat6 Plenum CMP, 1000 Feet

This is the strongest fit for buyers who need a clearly identified CMP cable with solid copper conductors. The listing specifies 23 AWG, four pairs, bare copper, 550 MHz bandwidth, and an easy-pull box. It states support for PoE, PoE+, and PoE++ up to 100 watts, and gives distance guidance of up to 328 feet for 1- and 5-Gigabit speeds and 165 feet for 10-Gigabit speeds, depending on installation conditions.
Best for: Installers who prioritize pure copper, plenum-rated cable, and stated PoE++ support. It was selected because its listed CMP jacket and conductor details directly address common plenum-installation and power-delivery concerns. Limitation: The 10-Gigabit distance is listed as up to 165 feet, not the longer distance stated for lower speeds.
MONK CABLES Pure Copper CMP, 1000 Feet

This MONK CABLES option lists 100% solid bare copper conductors, 23 AWG, UTP, a CMP-rated plenum jacket, 550 MHz, and support for 10-Gigabit Ethernet and PoE++. Its 1000-foot Reelex easy-pull box is intended to reduce snags during bulk cable installation. The listing also names routers, switches, patch panels, IP cameras, and PoE devices as example network uses.
Best for: Buyers planning a large structured-cabling project who want bare copper and a plenum rating in one bulk box. It was selected for the combination of explicit CMP wording and conductor details. Limitation: The supplied features do not state a specific PoE power limit or installation-distance table, so confirm requirements for the planned run.
MONK CABLES Cat6 Plenum, 1000 Feet

The product name identifies this as a 1000-foot Cat6 plenum cable with UTP construction, 23 AWG, and 550 MHz. The feature list says each cable is individually tested with a DSX-8000 cable certifier and references 568.2C standards. It also describes the conductors as a copper-and-aluminum mix, so this should not be treated as a solid-bare-copper alternative.
Best for: Buyers comparing bulk cable with stated individual testing who are willing to verify the exact jacket and conductor specifications before ordering. It was selected because the product name directly identifies plenum Cat6 cable and the listing provides testing details. Limitation: The copper-and-aluminum description indicates a CCA-type conductor; the listing’s “highest copper content” claim does not make it pure copper.
Brozzag Cat6 Cable, 1000 Feet

This 1000-foot listing describes 23 AWG, 550 MHz UTP cable, CCA conductors, a tangle-free easy-pull box, and batch testing with a DSX-8000 cable certifier. It says the cable supports up to 10 Gbps in short-run applications and is intended for projects where budget matters. However, its detailed features identify a CMR riser-rated jacket, despite the product name’s plenum wording.
Best for: Buyers seeking a long bulk spool for a suitable riser or other approved installation after checking local requirements. It was included because it is a Cat6 bulk cable with useful testing and performance details. Limitation: Do not assume it is CMP plenum cable; the provided features specify CMR, and its CCA conductors may not suit every PoE application.
Brozzag Cat6 Cable, 300 Feet

This shorter bulk option lists 23 AWG, 550 MHz, UTP, CCA conductors, and an easy-pull box. The listing says batches are DSX-8000 tested and describes support for 10-Gigabit speeds in short-run applications. As with the 1000-foot Brozzag listing, the detailed features call the jacket CMR, even though the product name includes “Plenum.”
Best for: Smaller cabling jobs where a 300-foot box is a closer fit than a full 1000-foot spool. It was selected as a size alternative with similar listed performance details. Limitation: The supplied features specify CMR rather than CMP, and recommend consulting the seller for high-power PoE applications.
Buying Guide: How To Choose Plenum-Rated Cat6 Cable
Do you need CMP or CMR cable?
Check where the cable will run and follow applicable building codes and project specifications. CMP is the plenum rating to look for when cable is required in a plenum air-handling space. CMR is a riser rating and is not interchangeable with CMP. Read the jacket markings and product specifications; do not rely on a product title alone when its detailed features conflict.
Should you choose copper or CCA?
Solid bare copper is the clearer choice when the installation calls for copper conductors or must support higher-power PoE. CCA cable uses copper-clad aluminum and may be marketed as a cost-conscious option, but it is not pure copper. Check equipment and project requirements before choosing CCA, particularly for powered devices.
How much cable should you buy?
Estimate the route length for every run, including vertical paths and service slack, then account for the number of connections. A 1000-foot box suits larger projects; a 300-foot box may better fit a smaller installation. Avoid selecting cable length based only on the straight-line distance between devices.
What performance details matter?
Compare the stated category, conductor gauge, bandwidth, testing information, and distance guidance. These listings identify Cat6 cable at 23 AWG and 550 MHz, but their conductor materials and jacket ratings differ. Treat 10-Gigabit distance claims as product-specific guidance rather than a guarantee for every installation.
Frequently Asked Questions
What does CMP mean on Cat6 cable?
CMP identifies a plenum-rated cable jacket. Confirm the rating on the product specifications and cable markings when the installation requires plenum cable.
Is CMR cable the same as plenum-rated cable?
No. CMR is a riser rating, while CMP is the plenum rating. The two labels should not be treated as interchangeable.
Is pure copper Cat6 preferable for PoE?
Pure copper is a useful selection criterion for PoE installations. Check the cable’s stated PoE support and the requirements of the connected devices before installation.
Can Cat6 support 10-Gigabit Ethernet?
The listed products describe 10-Gigabit support, but distance and installation conditions matter. Follow the individual product’s distance guidance and the requirements of the network equipment.
Should I choose a 300-foot or 1000-foot box?
Choose based on the measured cable needed for the project, including slack and all planned runs. The 300-foot option suits smaller jobs; the 1000-foot options are intended for larger bulk installations.
