TIA/EIA 568-A Cabling Standard

620004-0 Rev. B
B.1 Horizontal Wiring
The horizontal cable is the portion of the cabling system which extends from the
work area outlet to the telecommunications closet. The horizontal cabling is a star
topology, with a maximum cabling run of 90 meters (295 feet), independent of media
type.
The horizontal cable amounts to the greatest quantity of individual cables in the
building. Although the TIA/EIA 568-A standard helps limit cabling options, consid-
eration should be given to media type in order to support possible future needs. The
cable selected should accommodate more than one network planning period.
