UTP
EIA/TIA-568B specifies the maximum distance for a UTP horizontal cable run is 90 meters (295 feet) instead of the 100 meters that you are familiar with.
The other 10 meters can be distributed between the patch cables located at any horizontal cross connection (up to 6 meters) and the patch cables used to connect workstations in the work area (up to 3 meters).
In addition to UTP, the following cable types may be used for horizontal pathways:
- Shielded twisted pair (STP): Two-pair of 150 ohm cabling
- Fiber optic cabling: A two-fiber 62.5/125 µ optical fiber cable
