Cat6 CMP Plenum 1000ft UTP Ethernet Cable - Plenum Rated, 500MHz

In this review of the Cat6 CMP Plenum 1000ft UTP Ethernet Cable the bottom line is straightforward: this is a workhorse bulk cable for installers and IT managers who need a certified plenum-rated run that also supports PoE++ loads. The reviewer found its UL listed CMP jacket and 100% solid bare copper conductors to be the primary reasons to buy, because those attributes meet fire-safety codes and NEC requirements while delivering consistent electrical performance for long horizontal and vertical runs.

Key Features

• UL Listed Plenum Jacket: The low-smoke PVC jacket is CMP rated and self-extinguishes to reduce fire risk in air handling and plenum spaces.
• Solid Pure Copper Conductors: Built with 100% annealed solid bare copper to comply with NEC Section 800 and provide reliable signal and power delivery.
• PoE++ Capable: Four twisted pairs support up to 100W Power over Ethernet for cameras, access points, and other powered devices.
• 500MHz Performance: Rated to 500MHz, the cable supports Fast and Gigabit Ethernet applications with headroom for higher-frequency requirements.
• Reelex No-Tangle Box: The 1000ft reelex pull box reduces tangling and speeds cable deployment while sequential footage markings aid accurate measurement.
• Compliance and Origin: ETL and UL listed, TAA and Section 889 certified, and manufactured in the USA for government and commercial projects.

Who It's For

This cable is aimed at contractors, systems integrators, and facility IT teams who need plenum-rated CAT6 for building backbones, risers, and ceiling plenums where fire codes require CMP-rated materials. It is also suited to installations that will deliver power via PoE++ to cameras, access points, and other networked devices.

It is less suitable for casual home users who do not need plenum-rated cable or for projects that require shielded cable (STP) or a pre-terminated assembly; those buyers should consider non-plenum bulk options or pre-terminated runs instead.

Pros & Cons

Pros

• Certified CMP jacket improves safety in air handling spaces and meets UL standards.
• Solid 23AWG pure copper conductors provide consistent impedance and better long-run performance than CCA alternatives.
• PoE++ support and 500MHz rating future-proof common Gigabit and powered device needs.
• Reelex pull box and footage markings streamline installation and reduce handling time.

Cons

• Bulk spool requires termination in the field, so it is not plug-and-play for non-technical users.
• Plenum jacket can be slightly stiffer than general-purpose jacketed cables, which may affect tight bends in some conduit runs.

Our Verdict

The Cat6 CMP 1000ft plenum-rated bulk cable is a practical choice for professionals who must meet code and deliver reliable network power and data over long in-building runs. Its UL listed jacket, pure copper conductors, and PoE++ capability make it good value for commercial and government installations where safety and performance matter most.

Frequently Asked Questions

Is this cable suitable for plenum air spaces?
Yes. It is CMP plenum-rated and UL listed for use in air handling plenums and raised floors where low-smoke, self-extinguishing jacketing is required.

Can it deliver Power over Ethernet to cameras and APs?
Yes. The four twisted pairs and 23AWG solid copper conductors support PoE++ delivery up to 100W for powered devices.

Is the cable factory terminated?
No. It is bulk 1000ft cable on a reelex pull box intended for field termination to connectors or patch panels.
