Members of the committees serve voluntarily and without commission.

    24、 The companies that they represent are not necessarily members of the TIA. The standards developed within the TIA represent a consensus of the broad expertise on the subject. This expertise comes from within the TIA as well as those outside of the TIA that have an expressed interest. The viewpoint e

    25、xpressed at the time that this standard was approved was from the contributors experience and the state of the art at that time. Users are encouraged to verify that they have the latest revision of the standard. This standard has been prepared by the TR-42.7 Subcommittee and approved by the TR-42 En

    27、maximum cable diameter for 4-pair balanced UTP and ScTP cables. Deleted text is shown as strikethrough and new text is shown as underlined. 2 PURPOSE AND SCOPE This Standard specifies the requirements for the cable diameter of 4-pair balanced UTP and ScTP cables specified in TIA-568-B.2. 2.1 Applica

    28、bility This Standard applies to 4-pair balanced UTP and ScTP cables specified in TIA-568-B.2 and TIA-568-B.2-1. 3 NORMATIVE REFERENCES The following standards contain provisions that, through reference in this text, constitute provisions of this Standard. At the time of publication, the editions ind

    29、icated were valid. All standards are subject to revision; parties to agreements based upon this Standard are encouraged to investigate the possibility of applying the most recent editions of the standards indicated.

    31、 in clause 4.3.3.4 of TIA -568-B.2 shall be revised as follows: The diameter of the completed cable shall be less than 6.35 mm (0.25 in.) 9.0 mm (0.354 in). NOTE: Larger cable diameter cables may not be compatible with certain designs of modular connecting hardware. For example, the termination caps

    32、 in some modular outlets designs may not accommodate larger diameter cables. When 4-pair cables with overall diameters of greater than 6.35 mm (0.25 in.) are used, compatibility with connecting hardware should be considered.
