TIA/EIA-568-B.3 FOREWORD (This foreword is not a part of this Standard.) This Standard was developed by TIA/EIA Subcommittee TR-42.8. Approval of Standard This Standard was approved by TIA/EIA Subcommittee TR-42.8, TIA/EIA Engineering Committee TR-42, and the American National Standards Institute (ANSI). ANSI/TIA/EIA reviews standards every 5 years. At that time, standards are reaffirmed, rescinded, or revised according to the submitted updates. Updates to be included in the next revision should be sent to the committee chair or to ANSI/TIA/EIA. Contributing Organizations More than 30 organizations within the telecommunications industry contributed their expertise to the development of this Standard (including manufacturers, consultants, end users, and other organizations). Documents Superseded This Standard replaces, in part, ANSI/EIA/TIA-568-A, published October, 1995 and TIA TSB-72, published October, 1995. Significant technical changes from the previous edition — This foreword has been changed per the requirements of the TIA style manual. — All definitions have been harmonized across all of TIA’s telecommunications infrastructure standards. — Provides performance specifications for 50/125 m m optical fiber cables. — Provides a minimum bend radius and maximum pulling tensions for horizontal cable, inside plant cable, and outside plant optical fiber cable. — Allows for the use of alternate connector designs in addition to the 568SC. — Provides complete generic performance specifications for optical fiber connectors. — Specifies requirements for connecting hardware in support of centralized cabling. Relationship to other TIA standards and documents - Commercial Building Telecommunications Cabling Standard, Part 1, General Requirements (ANSI/TIA/EIA-568-B.1); - Commercial Building Standard for Telecommunications Pathways and Spaces (ANSI/TIA/EIA-569-A); - Residential Telecommunications Cabling Standard (ANSI/TIA/EIA-570-A); - Administration Standard for the Telecommunications Infrastructure of Commercial Buildings (ANSI/TIA/EIA-606); - Commercial Building Grounding and Bonding Requirements for Telecommunications (ANSI/TIA/EIA-607). - Customer-Owned Outside Plant Telecommunications Cabling Standard (ANSI/TIA/EIA-758). iii

TIA/EIA-568-B.3 The following documents may be useful to the reader: a) National Electrical Safety Code (NESC ) (IEEE C 2) b) National Electrical Code (NEC ) (NFPA 70) Useful supplements to this Standard are the Building Industry Consulting Service International (BICSI) Telecommunications Distribution Methods Manual, the Customer-owned Outside Plant Methods Manual, and the Cabling Installation Manual. These manuals provide practices and methods by which many of the requirements of this standard are implemented. Other references are listed in annex B. Annexes Annex A is normative and is considered a requirement of this Standard. Annex B is informative and not considered a requirement of this Standard. iv
