Approval of this Standard This Standard was approved by TIA Subcommittee TR-42.1, TIA En
35、gineering Committee TR-42, and the American National Standards Institute (ANSI). ANSI/TIA reviews standards every 5 years. At that time, standards are reaffirmed, withdrawn, or revised according to the submitted updates. Updates to be included in the next revision should be sent to the committee cha
36、ir or to ANSI/TIA. Contributing organizations More than 60 organizations within the telecommunications industry (including manufacturers, consultants, end users, and other organizations) contributed their expertise to the development of this Standard. Documents superseded This Standard supersedes AN
37、SI/TIA-568-C.1 dated February, 2009, and its addenda. Significant technical changes from the previous edition Significant changes from the previous edition include: The contents of Addendum 1 (pathways and spaces) and Addendum 2 (general up-dates) were incorporated. References were updated. Requirem
38、ents for multiuser telecommunications outlet assemblies and consolidation points were moved to ANSI/TIA-568.0-D. Requirements for associated spaces remain in this document pending revision of ANSI/TIA-569-D. Requirements for broadband coaxial cabling were added. 2-fiber minimum fiber count added for
39、 backbone cabling. The use of optical fiber array connectors in the work area is now supported. Annexes There is one annex to this Standard. Annex A is informative and not considered a part of this Standard. ANSI/TIA-568.1-D vi Relationship to other TIA standards and documents The following are rela
40、ted standards regarding various aspects of structured cabling that were developed and are maintained by Engineering Committee TIA TR-42.
