Cat 5e 350 MHz UTP Plenum Cable 1000ft - High-Speed Indoor Network

In this review the Vertical Cable Cat 5e 350 MHz UTP plenum cable is evaluated for installers and IT professionals who need a reliable, code-compliant bulk cable for indoor air plenums and roof ducts. The bottom line: this 1000 ft pull box delivers consistent performance for 350 MHz applications thanks to its 24 AWG solid bare copper conductors and ETL CMP listing, making it a practical choice when compliance and signal integrity matter most.

Key Features

• 350 MHz UTP performance: Supports higher frequency network runs for improved headroom over standard Cat 5e in dense or marginal installations.
• 24 AWG solid copper: Solid bare copper conductors provide stable signal transmission and suit punchdown and termination for keystone jacks and patch panels.
• ETL listed CMP: Fire resistant plenum rating allows legal installation in air plenums and roof ducts in accordance with NEC Article 800.
• 1000 ft pull box: Long single-reel supply reduces joins and splices on long runs and includes sequential length markings for easier installation planning.
• Clear pair identification: All four pairs are color striped for straightforward routing and termination during installation.

Who It's For

This cable fits network installers, building contractors and IT teams who must run Ethernet inside commercial plenum spaces or within conditioned ceilings and need a long continuous run without intermediate couplers. It is also suitable for structured cabling projects where meeting NEC Article 800 and using CMP-rated materials is required.

Those who need shielded cable for environments with heavy electromagnetic interference or armored outdoor-rated cable for direct burial should look elsewhere; this product is unshielded and intended for indoor plenum use only.

Pros & Cons

Pros

• ETL CMP listing gives confidence for plenum and roof duct installations where fire performance is required.
• Solid 24 AWG bare copper conductors provide consistent electrical characteristics for terminations and long runs.
• Sequential length markings and a 1000 ft pull box make measuring and deploying long runs faster and reduce waste.

Cons

• Unshielded design means it is not optimal for runs near heavy EMI sources where STP or shielded cable would be preferable.
