500‑foot Cat6 plenum cable for commercial installs

This 500 foot roll of Category 6 unshielded twisted pair cable uses 23AWG solid bare copper conductors and carries a CMP plenum fire safety rating. It is intended for installers running horizontal runs through air handling spaces in offices, schools and data centres where plenum rated cable is required by code.

Bandwidth tested to 550 MHz with 10 GbE support

The cable is tested to 550 MHz bandwidth and complies with IEEE 802.3af and 802.3at for Power over Ethernet and PoE+ delivery. Unshielded construction means it does not protect against external electromagnetic interference, so routing near heavy electrical equipment should be avoided.

Reelex II box with length markings for straight

The Reelex II packaging dispenses cable without twists, tangles or overruns, and the jacket includes sequential length markings for accurate cuts. Solid 23AWG conductors require a punch down tool or compatible modular plugs; they are not suited for direct termination into stranded only connectors or repeated flexing after installation.

Questions about this item

Should I choose the 500-foot roll or a shorter length for my installation?

The product is supplied as a single 500-foot roll with length markings on the jacket so you can cut exact lengths and track remaining cable.

What does the 550 MHz bandwidth rating mean for real-world throughput?

Tested to 550 MHz, the cable supports Category 6 performance up to 10 Gbps over short runs, suitable for server, cloud and video surveillance workloads.

Does the CMP plenum rating limit the cable to specific building spaces?

CMP rating means the jacket meets UL 444 and NEC TIA 568.2 D for plenum air spaces, so it can be installed in ducts and above suspended ceilings.
