Vertical Cable CAT6 Plenum 1000ft Bulk Ethernet Cable White - Made in

In this review the Vertical Cable CAT6 plenum bulk cable is examined for installers and IT teams who need a long run of reliable Ethernet wiring for commercial or residential plenum spaces. The bottom line: this 1000 ft spool of Cat 6 550 MHz UTP cable is aimed at network professionals who prioritize consistent performance and fire-safe routing in ceilings and roof plenums. Its solid 23 AWG bare copper conductors and ETL CMP rating make it a practical choice when a single continuous reel is preferable to patch cables or shorter runs.

Key Features

• 550 MHz performance: Supports higher frequency headroom than standard Cat6, which helps sustain gigabit and near-gigabit links over longer distances.
• 23 AWG solid copper: Solid bare copper conductors provide stable signal transmission and are preferred for permanent in-wall and rack terminations.
• Unshielded Twisted Pair (UTP): Offers flexibility and easier termination in standard jacks and patch panels without the need for shielded connectors.
• ETL listed CMP plenum: Rated for plenum and roof network installations, reducing flame and smoke risk where codes require plenum-rated cable.
• 1000 ft bulk spool: A full-reel length reduces joins and splices for long runs and is efficient for new builds or large retrofits.
• Made in USA: Domestic manufacturing can simplify sourcing and quality expectations for professional installers.

Who It's For

This cable is best for network installers, contractors, and IT departments wiring office ceilings, data closets, or multi-room residential systems where plenum-rated cable is required. The solid 23 AWG construction is ideal for permanent terminations to patch panels and wall plates rather than frequent re-patching.

Those who should look elsewhere include users who need stranded patch cable for frequent moves or devices that plug directly into equipment without wall jacks, and situations where shielded cable is required for high EMI environments.

Pros & Cons

Pros

• High-frequency 550 MHz rating offers extra performance margin for gigabit and future-proofed installs.
• ETL CMP plenum rating increases safety and compliance for plenum and roof spaces.
• Solid 23 AWG bare copper conductors deliver stable, low-loss links for fixed installations.
• Full 1000 ft spool minimizes joins and is economical for large projects.

Cons

• Unshielded construction may not suit very noisy electromagnetic environments where STP is preferable.
• As a solid bulk cable, it is less flexible than stranded patch cords for frequent handling.

Frequently Asked Questions

Is this cable plenum rated for use in air handling spaces?
Yes. The cable is ETL listed CMP, suitable for plenum and roof network installations where fire-resistant cable is required.

Can this be used for gigabit Ethernet and PoE?
Yes. The 550 MHz Cat 6 construction with 23 AWG solid copper conductors supports gigabit Ethernet and typical PoE power levels for fixed installations.

Is this cable shielded for high EMI areas?
No. This is unshielded twisted pair (UTP); consider shielded cable if you expect significant electromagnetic interference.
