Category cables are designed to carry high bit rate signals in LAN (Local Area Network) based systems using Ethernet protocols defined by IEEE.

Originally designed to operate at 1 MB these systems have evolved over time to the point where they are now able to communicate at bit rates of 1000 MB (also called Gigabit-Ethernet) and above.

Category cables are often employed in a STAR network topology. Such cabling is often referred to as Structured Cabling or Structured Wiring and involves using fixed solid conductor cable in horizontal runs radiating from a central MDF to workstation outlets. Category patch cable that has stranded conductors is then used for the last 5 metres of the run to connect the work outlet to the computer or workstation.

Standards such as AS/NZS 3080, ISO 11801 and EIA/TIA 568 specify the requirements for the cable and the subsequent channel or link. Typical protocols include 1Base5 (IEEE 802.3e), 10Base-T (IEEE 802.3i), 100Base-TX (IEEE 802.3u) and 1000Base-T (IEEE 802.3ab).

Garland category cable is designed to meet or exceed the necessary standards with many of the products being third part verified for performance by UL or ETL.

• Category 5e horizontal cables carry the UTPL5E insignia and are available in PVC (standard indoor), Halogen Free (“HF” suffix) and Jelly Filled versions (“JF” suffix) for outdoor and underground installations.
• Category 6 cables carry the UTPL6 insignia and are also available in the same options. Stranded versions (“MTP” suffix) are available in PVC or halogen free jacket options only.
