19、NTERNATIONAL ELECTROTECHNICAL COMMISSION _ OPTICAL FIBRE CABLES Part 1-1: Generic specification General FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The o
20、bject of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifica
21、tions (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non- governmental organizations li
22、aising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters expr
23、ess, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Commit
24、tees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC Nationa
25、l Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does no
26、t provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have t
27、he latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoeve
28、r, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publication
29、s is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. DISCLAIMER This Redline
30、 version is not an official IEC Standard and is intended only to provide the user with an indication of what changes have been made to the previous version. Only the current version of the standard is to be considered the official document. This Redline version provides you with a quick and easy way
31、 to compare all the changes between this standard and its previous edition. A vertical bar appears in the margin wherever a change has been made. Additions are in green text, deletions are in strikethrough red text. IEC 60794-1-1:2015 RLV IEC 2015 5 International Standard IEC 60794-1-1 has been prep
32、ared by subcommittee 86A: Fibres and cables, of IEC technical committee 86: Fibre optics. This fourth edition cancels and replaces the third edition, published in 2011. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to th
33、e previous edition: a) the expansion of the definitions, graphical symbols, terminology and abbreviations content, with the aim of making this standard the default and reference for all others in the IEC 60794-x series; b) the inclusion of updated and expanded optical fibre, attenuation and bandwidt
34、h sections, with the aim of making this standard the default and reference for all others in the IEC 60794-x series. The text of this standard is based on the following documents: CDV Report on voting 86A/1651/CDV 86A/1667/RVC Full information on the voting for the approval of this standard can be f
35、ound in the report on voting indicated in the above table. A list of all parts in the IEC 60794 series, published under the general title Optical fibre cables, can be found on the IEC website. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. The committee has deci
36、ded that the contents of this publication will remain unchanged until the stability date indicated on the IEC website under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended
37、. A bilingual version of this publication may be issued at a later date. IMPORTANT The colour inside logo on the cover page of this publication indicates that it contains colours which are considered to be useful for the correct understanding of its contents. Users should therefore print this docume
38、nt using a colour printer. 6 IEC 60794-1-1:2015 RLV IEC 2015 OPTICAL FIBRE CABLES Part 1-1: Generic specification General 1 Scope This part of IEC 60794 applies to optical fibre cables for use with communication equipment and devices employing similar techniques and to cables having a combination of
39、 both optical fibres and electrical conductors. The object of this standard is to establish uniform generic requirements for the geometrical, transmission, material, mechanical, ageing (environmental exposure), climatic and electrical properties of optical fibre cables and cable elements, where appr
