36、Standard was developed by TIA Subcommittee TR-42.1. 112 Approval of this Standard 113 This Standard was approved by TIA Subcommittee TR-42.1, TIA Engineering Committee 114 TR-42, and the American National Standards Institute (ANSI). 115 ANSI/TIA reviews standards every 5 years. At that time, standar
37、ds are reaffirmed, withdrawn, or 116 revised according to the submitted updates. Updates to be included in the next revision should 117 be sent to the committee chair or to ANSI/TIA. 118 Contributing organizations 119 More than 60 organizations within the telecommunications industry (including manuf
38、acturers, 120 consultants, end users, and other organizations) contributed their expertise to the development 121 of this Standard. 122 Documents superseded 123 This Standard supersedes ANSI/TIA-1179 dated July, 2010. 124 Significant technical changes from the previous edition 125 Significant change
39、s from the previous edition include: 126 References were updated. 127 The document was restructured to be in the same general format as ANSI/TIA-568.1-D. 128 Balanced twisted-pair backbone cabling is now category 6A. 129 Balanced twisted-pair horizontal cabling is now category 6A. 130 OM4 or OM5 are
40、 recommended for multimode optical fiber cable. 131 OM1, OM2 and OS1 cabling are no longer supported. 132 Minimum two fibers are now required for optical fiber backbone cabling. 133 Array connectors are now permitted for optical fiber cabling in the work area. 134 MUTOA and consolidation points may
41、be used as additional network elements. 135 Requirements were added for: 136 o telecommunications pathways and spaces (additional requirements to those in 137 ANSI/TIA-569-D) 138 o bonding and grounding 139 o firestopping 140 o broadband coaxial cabling 141 o multi-tenant building spaces 142 Recomme
42、ndations were added for cabling for: 143 o wireless access points 144 o distributed antenna systems 145 146 ANSI/TIA-PN-1179-A vi Relationship to other TIA standards and documents 147 The following are related standards regarding various aspects of structured cabling that were 148 developed and are
