This Addendum was developed
26、by TIA Subcommittee TR-42.1. Approval of this Addendum This Addendum was approved by TIA Subcommittee TR-42.1, TIA Engineering 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 At that time, standards are reaffirmed, withdrawn, or revise
27、d according to the submitted updates. Updates to be included in the next revision should be sent to the committee chair or to ANSI/TIA. Annexes There are no annexes to this Addendum. Introduction Since the time of publication of ANSI/TIA-568.1-D two documents have been published by TIA TR-42 subcomm
28、ittees which affect its content. In response, this Addendum revises references and accommodates new media types. Specifically: ANSI/TIA-568-C.2-1 specified a new balanced twisted-pair media type, category 8, specified to 2 GHz. Category 8 cabling supports 30-meter, 2 connection channels. ANSI/TIA-56
29、8.3-D is published. Cabling transmission performance and test requirements for optical fiber cabling, guidelines for maintaining optical fiber polarity, and guidelines for field testing of optical fiber cabling are now contained in this revision, eliminating the need to reference ANSI/TIA-568-C.0 fo
30、r this information. In addition, a new media type, OM5 wideband laser-optimized multimode optical fiber cabling, is specified. OM1, OM2 and OS1 cabling is no longer supported. ANSI/TIA-568.1-D-1 1 1 SCOPE This Addendum updates references and accommodates new media types introduced by ANSI/TIA-568-C.
