This Standard provides structure, topologies and distances, installation, performance, and testing requirements for generic telecommunications cabling.  This Standard forms the foundation for premises telecommunications cabling infrastructure design and can be used to address cabling needs when a specific premise standard (e.g., TIA-568.1-D for commercial building cabling) does not exist.

ANSI/TIA-568.0-D “Generic Telecommunications Cabling for Customer Premises” was developed by the TIA TR-42.1 Commercial Building Cabling Subcommittee and originally published in September, 2015.  It was identified that several formulas in the Standard were not rendering correctly and the document was revised and reaffirmed in December, 2015.  Significant changes from the previous edition include:

  • Category 5e or higher rated cabling is required for all generic balanced twisted-pair cabling deployments
  • OM3 or higher rated cabling is required for all generic multimode optical fiber cabling deployments
  • The minimum fiber count for generic multimode and singlemode optical fiber cabling deployments has changed from one fiber to two fibers per port/channel
  • Broadband coaxial cabling has been added as a recognized media
  • Information on optical fiber polarity and optical fiber testing has been moved to TIA-568.3-D
  • Requirements for open office cabling (i.e., consolidation points, multi-user telecommunications outlet assemblies) have been moved into this Standard
  • The minimum inside bend radius for balanced twisted-pair cord cable has been increased to four times the overall cable diameter
  • The minimum inside bend radius for optical fiber cord cable is specified as 25 mm (1 in)
  • A new Annex provides guidelines on shared pathways and shared sheaths for balanced twisted-pair cabling
  • The contents of TIA-568-C.0-1 (updated references) and TIA-568-C.0-2 (general updates) were incorporated

ANSI/TIA-568-0.D-1 “Addendum 1, Updated References, Accommodation of New Media Types” published in July, 2017 and provides modification text to TIA-568-0-D to recognize category 8 balanced twisted-pair and OM5 multimode optical fiber media types.
