| 8.10.6 | Patch cables contribute to the overall length of the cabling segment
Patch cables are typically three meters in length and often used for either connecting two MAUs (in a token ring topology) together or connecting two Ethernet hubs together. Patch cables are also used to "patch" a system with a NIC to the digital jack on either a cube wall or floor mount. The TIA/EIA-568-A standards govern horizontal cable installations. For Cat 5 UTP, the distance limitation is 100 meters, of which 3 meters are designated for workstation patch cables, 90 meters for horizontal cable runs (from the outlet to the Horizontal Cross Connect, or HCC), and 6 meters for patch cables/jumper cables within the HCC.
