Vertical Cable Cat6 550 MHz UTP Plenum 1000ft - High-Speed Bulk Cable

Our review of the Vertical Cable Cat 6 550 MHz UTP Plenum 1000ft spool finds it best suited for installers and IT teams who need a long, reliable run of bulk Ethernet cable for plenum or roof spaces. The single biggest reason to buy is its combination of a 550 MHz performance rating and ETL listed CMP plenum rating, which together deliver higher bandwidth headroom while meeting fire-safety requirements for air-handling spaces. This review focuses on real-world installation use, conductor quality, and where the cable fits into commercial or residential backbone runs.

Key Features

• 550 MHz performance: Provides higher frequency headroom for Gigabit and some 10 Gig-capable runs, helping reduce crosstalk and maintain signal integrity over long distances.
• 23 AWG solid bare copper: Solid conductors deliver stable connections and lower attenuation compared with smaller or stranded alternatives, which is useful for wall terminations and patch panels.
• Unshielded Twisted Pair (UTP): Flexible for standard Ethernet installations where shielding is not required and simplifies terminations with typical RJ45 connectors.
• ETL listed CMP plenum rating: Approved for plenum and roof network installations where flame retardant properties and low smoke are required by code.
• 1000 ft bulk spool: One continuous run reduces joins and splices for long runs in risers or between floors, saving installation time and materials.
• Made in USA: Domestic manufacture can simplify quality expectations and sourcing for commercial projects.

Who It's For

The cable is aimed at professional network installers, data center technicians, and building contractors who need a code-compliant plenum-rated Cat6 bulk cable for long runs through plenum spaces or roof cavities. It works well for backbone runs, horizontal cabling in new builds, and situations where a single 1000 ft spool reduces waste and time spent joining multiple shorter reels.

Home users with small patch needs or installers who require shielded cable for high-EMI environments should look elsewhere; this UTP cable does not provide shielding and is optimized for plenum safety and stable copper performance rather than specialty noise rejection.

Pros & Cons

Pros

• High 550 MHz rating gives extra bandwidth margin and improved crosstalk performance for demanding network links.
• 23 AWG solid bare copper conductors provide reliable terminations and low attenuation for longer runs.
• ETL CMP plenum rating allows installation in air-handling and plenum spaces to meet code requirements.
• 1000 ft spool reduces splices and speeds up installation on larger projects.

Cons

• Being UTP, it lacks shielding for environments with high electromagnetic interference where STP/FTP would be preferable.
• The bulk 1000 ft length may be overkill for small residential jobs and requires adequate storage and handling space.

Our Verdict

The Vertical Cable Cat6 550 MHz UTP plenum 1000 ft spool is a strong choice for contractors and IT teams that require a plenum-rated, high-performance bulk cable with reliable solid copper conductors. It offers good value for larger installations where a single continuous run reduces joins, and its ETL CMP listing makes it appropriate for building code-sensitive deployments.

Frequently Asked Questions

Is this cable suitable for plenum spaces?
Yes, it is ETL listed CMP and designed for plenum and roof network installations where flame retardant materials are required.

Can this cable be used for 10 Gigabit Ethernet?
Its 550 MHz rating gives additional headroom; while Cat6 can support 10GBASE-T at shorter distances, performance depends on run length and installation quality.

Is the conductor stranded or solid?
The product uses 23 AWG solid bare copper conductors, which are preferred for permanent in-wall and patch panel terminations.
