Cat6 Network Cables

About Cat6 Network Cables

TMT’s Cat6 range spans six constructions: U/UTP, F/UTP, U/FTP, F/FTP, S/FTP and flat cable. Every Cat6 cable in the current range is a four-pair, 23 AWG cable, and almost every model is supplied on a 305 m reel. Jacket choices are PVC, LSZH and PE for outdoor routes.

Selection usually comes down to two questions: does the route need a screened construction, and is the run indoors, in a low-smoke area or outside? To compare categories see Cat6A and Cat5e. Matching Cat6 patch cords and connectivity are also available, and the Network Cable Selection Guide explains the trade-offs.

Conductor size (AWG)

All TMT Cat6 cables use 23 AWG conductors, a slightly larger conductor than the 24 AWG used across the Cat5e range. The conductor size is listed on every product page and datasheet.

Where each construction is used

• U/UTP for general horizontal cabling in offices and buildings.
• F/UTP, U/FTP, F/FTP and S/FTP where the route runs close to electrical interference.
• PE-jacketed versions for outdoor and external runs, and LSZH where low smoke and zero halogen are required.
• Flat Cat6 lift cables (U/UTP and F/UTP) for lift and elevator installations.

Wiring and termination

See the Cat5e and Cat6 colour code guide (T568A / T568B), and terminate with RJ45 connectors or keystone jacks.

Cat6 speed and distance

Cat6 is rated to 250 MHz. It carries 1 Gbit/s over the full 100 m channel and 10GBASE-T over shorter runs, up to about 55 m in good conditions. For 10G over 100 m choose Cat6A.

FAQ

Is Cat6 good for PoE? Yes. 23 AWG conductors keep resistance low for PoE cameras and access points.

Cat6 or Cat5e? Cat6 has tighter crosstalk limits and more headroom. See the Cat5e vs Cat6 vs Cat6A guide.
