Cat6 Shielded Plenum CMP 1000ft Bulk Cable - High Performance

In this review of the Cat6 Shielded Plenum (CMP) 1000ft bulk cable, the bottom line is simple: installers and network professionals who need a code-compliant, high-performance cable for plenum and riser spaces will find strong value here. The cable delivers a solid combination of 550MHz bandwidth, solid 23AWG bare copper conductors, and a full foil shield that reduces crosstalk, making it especially useful where consistent Gigabit Ethernet and reliable Power over Ethernet are required.

Key Features

• 1000ft bulk reel: A full wooden reel with length markings every 2 ft makes long runs and inventory management straightforward on job sites.
• Shielded plenum jacket: CMP-rated FRPVC jacketing reduces flame spread and smoke toxicity so the cable meets plenum space fire and safety requirements.
• Solid 23AWG copper: Solid bare copper conductors provide optimal signal strength and mechanical reliability for terminated runs and keystone jacks.
• Overall foil shield with spline: The foil shield and internal spline offer extra headroom against crosstalk, improving performance margin over TIA/EIA limits.
• High frequency support: Rated to 550MHz and Fluke tested, it supports 1Gb at 328 ft and higher multi-gigabit speeds at shorter distances.

Who It's For

This cable is aimed at professional installers, systems integrators, and building IT managers who must run network cabling through air-handling plenums, drop ceilings, or raised floors while meeting building inspection and safety codes. The wooden reel and length markers also make it practical for contractors doing multiple office or campus runs.

It is less suitable for casual home users who only need a few patch cables or short runs; smaller quantities or pre-terminated cables are better for hobbyists and non-professional installs where plenum rating and bulk reels are unnecessary.

Pros & Cons

Pros

• Plenum-rated jacket and UL listings make it acceptable for air-handling spaces and building inspections.
• Solid 23AWG pure copper and overall shield boost signal integrity and PoE reliability.
• Marked every 2 ft on a wooden reel for easier measuring and deployment on site.
• Supports multi-gigabit applications and is Fluke tested for consistent quality.

Cons

• Bulk reel and solid conductors require field termination or keystone jacks, which adds labor for those needing ready-made patch cables.

Frequently Asked Questions

Can I use this cable for PoE and PoE+ devices?
Yes. The solid 23AWG conductors and shielded design support PoE and PoE+ power delivery reliably over standard Ethernet runs.

Is this cable suitable for plenum spaces and building inspections?
Yes. The CMP plenum FRPVC jacket and UL listing make it appropriate for air-handling plenums and compliant with common building code requirements.

Will it run 10Gb Ethernet?
The cable supports up to 550MHz and can achieve 10Gb at shorter distances; standard 1Gb is supported at the full 328 ft (100 m) distance.
