Cat5e Plenum Ethernet Cable 275ft Red - High-Speed Solid Copper

Our review of the Cat5e Plenum Ethernet Cable 275ft Red finds it aimed at installers and IT pros who need a long, plenum-rated run with dependable performance. The single biggest reason to buy is the combination of a full 275ft reel, solid 24 AWG copper conductors, and CMP plenum jacket that meets commercial air space requirements, making it a practical choice for office, studio, or home theater installs that pass through ceiling or air-handling spaces.

Key Features

• Length and visibility: The 275ft red jacket provides a long continuous run with easy visual identification on cable bundles or in racks.
• Plenum CMP rating: The fire-resistant, low-smoke jacket is suitable for plenum or air handling spaces required by commercial codes.
• Solid copper conductors: 24 AWG solid copper cores preserve signal integrity and are ideal for permanent wall or conduit runs.
• High performance: Category 5e construction supports performance up to 350MHz and gigabit Ethernet speeds for typical LAN and PoE needs.
• Durable connectors: EZ pass-through RJ45 connectors with gold-plated contacts and strain-relief boots deliver a reliable, low-loss termination.
• Assembled in USA: Cable is assembled in the United States with foreign and domestic parts, providing traceable production and quality control.

Who It's For

This cable is best for network installers, AV technicians, building contractors, and IT departments that must run Ethernet in commercial plenum spaces or want a long, visible run for structured cabling. The solid 24 AWG conductors and CMP jacket make it a suitable choice for permanent installations in offices, studios, data closets, and residential builds where fire codes require plenum-rated cable.

Users who need highly flexible patch cords, shorter jumper cables, or outdoor-rated runs should look elsewhere; this product is optimized for in-wall and in-ceiling wired connections rather than repeated flexing or direct burial.

Pros & Cons

Pros

• Solid 24 AWG copper cores that maintain signal quality for long runs.
• CMP plenum jacket meets commercial plenum requirements and reduces fire and smoke risk.
• EZ pass-through RJ45 connectors with strain-relief boots for durable terminations.
• Long 275ft length useful for extended single-run installations and clear red jacket for easy identification.

Cons

• Solid-conductor cable is less flexible than stranded patch cords and not ideal for repeated movement.
• Plenum jackets cost more than non-plenum alternatives, which may be unnecessary for some residential installs.
