Quick Glance
Key Features
Riser (CMR)-rated, fire-resistant jacket
Ubiquiti rates the cable CMR to the UL 1666 flame test, for indoor deployments such as vertical runs between floors. The white jacket is flame retardant polyvinyl chloride (FRPVC), 5.9 ± 0.2 mm in diameter.
Category 6 UTP with anti-crosstalk divider
Four colour-coded twisted pairs of 23 AWG solid bare copper are separated by an anti-crosstalk divider, with a ripcord to strip the jacket. Ubiquiti lists electrical transmission standards ANSI/TIA-568.2-D, ISO/IEC 11801 (Edition 2.2) and IEC 61156-5 (Edition 2.1).
305 m box for building-wide runs
One box holds 305 m (1,000 ft) of cable. The box measures 476 x 306 x 419 mm and weighs 14.6 kg. Install between 0 and 60°C, keep bends to a minimum radius of 24 mm, and operate from -20 to 60°C.
Detailed Specifications
Specifications are taken from Ubiquiti's official technical specifications and store listing for the UniFi Indoor Cable Cat6 CMR, U-Cable-C6-CMR. Ubiquiti does not state a data rate or maximum link length for this cable.
Need-to-Know
- This is an indoor cable: Ubiquiti lists its operating environment as Indoor. For outdoor runs, choose a cable Ubiquiti rates for outdoor use.
- CMR is the riser flame rating (UL 1666). Ubiquiti also makes a plenum-rated version, the UniFi Indoor Cable Cat6 CMP (U-Cable-C6-CMP), for environments that require plenum-rated cabling.
- Ubiquiti lists no connectors for this cable and its text states no data rate or maximum link length. Terminate it with connectors suited to solid 23 AWG conductors.
- Install the cable between 0 and 60°C and keep bends no tighter than the 24 mm minimum bend radius.

Frequently Asked Questions
The CMR version is riser-rated to the UL 1666 flame test. Ubiquiti also sells a plenum (CMP)-rated version, the U-Cable-C6-CMP, for environments that require plenum-rated cabling. Both are 305 m boxes of Category 6 UTP cable with 23 AWG solid bare copper conductors and an anti-crosstalk divider.
One box holds 305 m (1,000 ft) of cable. Ubiquiti gives the box dimensions as 476 x 306 x 419 mm and the box weight as 14.6 kg (32.2 lb).
