Cat5e CMP Plenum 1000ft UTP Ethernet Cable - True Plenum Rated

In this review of the Cat5e CMP Plenum 1000ft UTP Ethernet Cable, the bottom line is straightforward: install-grade network professionals and contractors who need a code-compliant, plenum-rated bulk cable will appreciate this reel for safe, long runs in air handling spaces. The cable's primary strength is its combination of UL listed plenum rating and 100% solid bare copper conductors, which together deliver both fire safety and reliable signal performance for PoE devices and structured cabling installations.

Key Features

• UL Listed Plenum Cable: The CMP jacket is low-smoke PVC that self-extinguishes and reduces re-ignition risk, meeting plenum safety needs in ducts and raised floors.
• NEC Compliant Conductors: Built with 100% annealed solid bare copper to meet NEC Section 800.179 for communications wiring and to ensure consistent conductivity.
• PoE++ Capable: Supports up to 100W Power over Ethernet, suitable for powering security cameras, access points, and other powered network devices.
• Performance to 350MHz: Designed to support Fast Ethernet and Gigabit Ethernet applications while maintaining signal integrity over long runs.
• Reelex No-Tangle Pull Box: The 1000 ft reelex box eases installation, prevents unwinding hassles, and includes sequential footage markings for precise length tracking.
• USA Made and Compliant: Manufactured in the USA with TAA and Section 889 compliance, UL and ETL verification, and RoHS conformance for procurement-sensitive projects.

Who It's For

This cable is aimed at installers, building managers, and contractors who must run network cable in plenum spaces or other air-handling areas where code-compliant materials are required. It is also a good choice for organizations that demand solid copper conductors for long-term reliability and for deployments that will use PoE cameras or access points.

Home users or hobbyists who do not need plenum-rated cable can find less expensive non-plenum Cat5e options; likewise, projects that require shielded or higher-category cabling for multi-gigabit or specialized environments should look toward Cat6a or shielded variants instead.

Pros & Cons

Pros

• True plenum-rated jacket and UL listing provide peace of mind for code-compliant installations.
• 100% solid bare copper conductors deliver stable signal and better PoE power handling compared with copper-clad options.
• REELEX pull box reduces tangle and speeds up long-run installations, with footage markings for accurate measuring.

Cons

• Plenum-rated cable typically costs more than non-plenum Cat5e, which may be unnecessary for some projects.

Our Verdict

The Cat5e CMP plenum 1000 ft reelex cable is a practical choice for professional installations that require code-compliant, plenum-rated wiring and reliable PoE performance. It represents good value where safety, NEC compliance, and solid copper conductors matter most, though casual users with no plenum requirement may opt for a lower-cost non-plenum alternative.
