3、SA T568.3, Optical fiber cabling components standard. It replaces CSA T529-95, Telecommunications Cabling Systems in Commercial Buildings. This Standard is an adoption of the identically titled ANSI/TIA/EIA (American National Standards Institute/Telecommunications Industry Association/Electronic Ind

4、ustries Alliance) Standard 568-B.3-2000 and is the product of the Telecommunications Industry Association TR-42 Technical Committee, which included a number of Canadian members in order to ensure that Canadian perspectives and requirements were addressed. It is written in SI (metric) units with yard

5、/pound (imperial) units in parentheses. This Standard has been adopted with no technical deviations. Where code requirements or regulations necessitate changes from US to Canadian references, they should be made by the user, as follows: (a) Throughout this Standard, replace the term “American” with

6、“Canadian”, as applicable. (b) Throughout this Standard, replace the term “state” with “provincial or territorial”, as applicable. (c) Throughout this Standard, replace “NEC” with “CE Code, Part I” (Canadian Electrical Code), as applicable. In addition, (i) where reference is made to “conduit”, repl

7、ace it with “conduit/EMT” (electrical metallic tubing) because, in accordance with the Canadian Electrical Code, Part I, EMT is not considered a type of conduit; and (ii) the definitions of the following terms are to be taken from the Canadian Electrical Code, Part I: “Bonding”, “Ground”, and “Racew

8、ay”. (d) Throughout this Standard, where reference is made to “FCC”, replace it with “CRTC” (Canadian Radio-television and Telecommunications Commission), or “Industry Canada”, as applicable. (e) The following Standard, published by the Canadian Standards Association, is an adoption of a TIA/EIA Sta

9、ndard. The requirements of this CSA Standard take precedence over the TIA/EIA Standard on which it is based; any reference in CSA T568.3 to the TIA/EIA Standard is to be replaced by a reference to the equivalent Canadian Standard: T568.1-05, Commercial building telecommunications cabling standard Pa

10、rt 1: General requirements. (f) Throughout this Standard, replace the term “Listed” with “Approved as applied to electrical equipment”. This Standard was reviewed for Canadian adoption by the CSA Technical Committee on Telecommunications Wiring Systems, under the jurisdiction of the Strategic Steeri

11、ng Committee on Information and Communications Technology, and has been formally approved by the Technical Committee. A list of the members of the Technical Committee is available upon request.

Annex B is informative and notconsidered a requirement of this Standard.TIA/EIA-568-B.311. INTRODUCTION1.1 PurposeThis Standard specifies the

40、component and transmission requirements for an optical fiber cabling system(e.g., cable, connectors). 50/125 m and 62.5/125 m multimode, and singlemode optical fiber cables arerecognized cables.1.2 Specification of criteriaIn accordance with EIA Engineering Publication, EP-7B, two categories of crit

41、eria are specified; mandatoryand advisory. The mandatory requirements are designated by the word “shall“; advisory requirements aredesignated by the words “should”, “may“, or “desirable“ which are used interchangeably in this Standard.Mandatory criteria generally apply to protection, performance, ad

42、ministration and compatibility; they specifythe absolute minimum acceptable requirements. Advisory or desirable criteria are presented when theirattainment 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

43、 emphasis or offering informative suggestions.1.3 Metric equivalents of US customary unitsThe majority of the metric dimensions in this Standard are soft conversions of US customary units; e.g., 100millimeters (mm) is the soft conversion of 4 inches (in).1.4 Life of the StandardThis Standard is a li
