This Standard was developed by TIA/EIA Subcommittee TR-42.8. Approval of Standard This Standard was

26、approved by TIA/EIA Subcommittee TR-42.8, TIA/EIA Engineering Committee TR-42, and the American National Standards Institute (ANSI). ANSI/TIA/EIA reviews standards every 5 years. At that time, standards are reaffirmed, rescinded, or revised according to the submitted updates. Updates to be included

27、in the next revision should be sent to the committee chair or to ANSI/TIA/EIA. Contributing Organizations More than 30 organizations within the telecommunications industry contributed their expertise to the development of this Standard (including manufacturers, consultants, end users, and other orga

28、nizations). Documents Superseded This Standard replaces, in part, ANSI/EIMIA-568-A, published October, 1995 and TIA TSB-72, published October, 1995. Significant technical changes from the previous edition - This foreword has been changed per the requirements of the TIA style manual. - All definition

29、s have been harmonized across all of TIAS telecommunications infrastructure standards. - Provides performance specifications for 50/125 pm optical fiber cables. - Provides a minimum bend radius and maximum pulling tensions for horizontal cable, inside plant cable, and outside plant optical fiber cab

30、le. - Allows for the use of alternate connector designs in addition to the 568SC. - Provides complete generic performance specifications for optical fiber connectors. - Specifies requirements for connecting hardware in support of centralized cabling.

INTRODUCTION 1 .I Purpose This Standard specifies the component and transmission requirements for an optical fiber cabling system (e.g., cable,

37、 connectors). 50/125 pm and 62.U12.5 pm multimode, and singlemode optical fiber cables are recognized cables. 1.2 Specification of criteria In accordance with EIA Engineering Publication, EP-7B, two categories of criteria are specified; mandatory and advisory. The mandatory requirements are designat

38、ed by the word “shall“; advisory requirements are designated by the words “should“, “may“, or “desirable“ which are used interchangeably in this Standard. Mandatory criteria generally apply to protection, performance, administration and compatibility; they specify the absolute minimum acceptable req

39、uirements. Advisory or desirable criteria are presented when their attainment will enhance the general performance of the cabling system in all its contemplated applications. A note in the text, table, or figure is used for emphasis or offering informative suggestions. 1.3 Metric equivalents of US c

40、ustomary units The majority of the metric dimensions in this Standard are soft conversions of US customary units; e.g., 100 millimeters (mm) is the soft conversion of 4 inches (in). 1.4 Life of the Standard This Standard is a living document. The criteria contained in this Standard are subject to re

41、visions and updating as warranted by advances in building construction techniques and telecommunications technology. 1 Copyright Telecommunications Industry Association Provided by IHS under license with EIANot for ResaleNo reproduction or networking permitted without license from IHS-,-,-TINEIA-568

42、-B.3 2. SCOPE 2.1 Applicability This Standard specifies minimum requirements for optical fiber components used in premises cabling, such as cable, connectors, connecting hardware, patch cords and field test equipment. 2.2 Normative references The following standards contain provisions that, through

43、reference in this text, constitute provisions of this Standard. At the time of publication, the editions indicated were valid. All standards are subject to revision; parties to agreements based on this Standard are encouraged to investigate the possibility of applying the most recent editions of the

44、 standards indicated. ANSI and TIA maintain registers of currently valid national standards published by them.
