The ANSI/TIA-568-C series of standards is a family of our individual documents.
Note: the 568-C series will replace ANSI/TIA-568-B series in 2008.
X
ANSI/TIA-568-C.0: "Generic Telecommunications Cabling for Customer Premises".
X
ANSI/TIA-568-C.1: “Commercial Building Telecommunications Cabling Systems
Standard”.
X
ANSI/TIA-568-C.2: “Balanced Twisted Pair Telecommunications Cabling 
Systems 
Standard”.
X
ANSI/TIA-568-C.3: “Optical Fiber Telecommunications Cabling Systems Standard”.
ANSI/TIA-568-C.0 defines the overall premises infrastructure for copper and fiber 
cabling. Detailed requirements for cabling installation and field-testing are also included. 
TIA-568-C.1 provides detailed design requirements for horizontal and backbone cabling 
infrastructure and distribution facilities. TIA-568-C.2 and C.3 establish component level 
testing and prformance requirements for copper and fiber connecting hardware 
respectively.
ANSI/TIA-568-C.0 and C.1: Horizontal Cabling 
(previously 568-B.1)
The horizontal cabling in a building is a single floor cable distribution from the 
horizontal cross connect (HC) in the telecommunications room (TR) to the work area (WA) 
outlet.
Recognized Horizontal Cables
X
4-Pair 100
: UTP or Screened Twisted Pair (ScTP), Category 3, 5e, 6, and 6A.

• Minimum 2-Strand Multimode Fiber Optic Cable.
X
150
: Shielded Twisted Pair (STP).
Horizontal Cable Minimum Bend Radius and Pull Force
X
4-Pair UTP: 4 times cable diameter.
• Maximum pull force: 25 lbs.
X
Fiber Cable: 10 times cable diameter.
• See pages N14 and N15 for Pull Forces.
NOTE: See pages N14 and N16 for Installation Practices.
