T568.1-05 (R2010)

CSA Preface This is the first edition of CSA T568.1, Commercial building telecommunications cabling standard - Part 1: General requirements. It replaces CSA T529-95, Telecommunications Cabling Systems in Commercial Buildings. This Standard is an adoption of the identically titled ANSI/TIA/EIA (American National Standards Institute/Telecommunications Industry Association/Electronic Industries Alliance) Standard 568-B.1-2001 and is the product of the Telecommunications Industry Association TR-42 Technical Committee, which included a number of Canadian members in order to ensure that Canadian perspectives and requirements were addressed. It is written in SI (metric) units with yard/pound (imperial) units in parentheses. SCOPE This Standard specifies minimum requirements for telecommunications cabling within a commercial building and between buildings in a campus environment. It specifies cabling requirements, cabling distances, telecommunications outlet/connector configurations, and a recommended topology. Building telecommunications cabling specified by this Standard is intended to support a wide range of different commercial building sites and applications (e.g., voice, data, text, video, and image). Typically, this range includes sites with a geographical extent from 3 000 m (approximately 10 000 ft), up to 1 000 000 m2 (approximately 10 000 000 ft2) of office space, and with a population of up to 50 000 individual users. Telecommunications cabling systems specified by this Standard are intended to have a useful life in excess of ten years. This Standard applies to the telecommunications cabling systems of buildings for commercial enterprises that are office oriented.
