Everything You Need to Know About Cat6 Plenum Cable

Due to its heavy shielding, Cat6 Plenum Bare Copper cable provides excellent data transfer rates and bandwidth capacities. Cat6a  bare copper supersedes Cat5e, and Cat6a replaces the cable. Though it is also available in copper-clad aluminum, pure copper outperforms the CCA variant in every way. The following are some key points to remember about Cat6 Plenum 1000ft:

Conductors made entirely of copper

The inner structure is made up of eight pure copper conductors twisted into four pairs. Each conductor is wrapped in an insulation material to isolate current flow and prevent direct contact between the eight conductors (usually plastic). The Cat6 Plenum, 1000ft insulation, ensures that signal quality is not harmed.

Protected vs. Unprotected

Cat6 Shielded and unshielded versions of bare copper ethernet cable are available.

All four twisted pairs can be wrapped in either a screening material or shielding in shielded versions. Copper braid jackets or foil wrappings provide an additional layer of protection. The shielded Cat6 Bare Copper cables are ideal for high-crosstalk and EMI environments.

The unshielded Cat6 Solid Copper cable lacks this extra layer of protection and is best used in areas where crosstalk and interference are minimal.

Jacket Fabric

Jacket ratings for the Cat6 Plenum Bare Copper are CMP (Communications Multipurpose Cable, Plenum). Because of their fire-retardant qualities, cables with CMP jacket ratings are permitted to be used in the plenum spaces of buildings. When exposed to fire, these cables produce no smoke or hazardous gases, effectively stopping the spread of the fire.

Plenum cables can also be used in riser spaces, but they cannot be turned.

Bandwidth Capacity & Data Transfer Rates

Plenum Cat6 10Gbps data transfer rates up to 50 meters (164 feet) and 1Gbps data transfer rates up to 100 meters (328 feet) are supported by bare copper cables. This cable has a 550MHz bandwidth capability. Because we’re dealing with pure copper cables, these variations easily meet the aforementioned ideal standards.

Cat6 Plenum Bare Copper Wire Gauge ranges from 22AWG to 26AWG. Because it’s a bulk cable, it’s packaged in an easy-to-pull box.


A high-quality Cat6 plenum should pass the Fluke DXT-1800 Versic Cab test and meet all TIA and ANSI requirements. Aside from being RoHS compliant, it should also meet all FCC, CSA, and CE standards.
