27、EC 24702 20 4 60794-2-30 IEC:2008 INTERNATIONAL ELECTROTECHNICAL COMMISSION _ OPTICAL FIBRE CABLES Part 2-30: Indoor cables Family specification for ribbon cables FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national e
28、lectrotechnical committees (IEC National Committees). The object 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 Spec
29、ifications, Technical Reports, Publicly Available Specifications (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. Interna
30、tional, governmental and non- governmental organizations liaising 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 form
31、al decisions or agreements of IEC on technical matters express, 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 fo
32、r international use and are accepted by IEC National Committees 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
33、) In order to promote international uniformity, IEC National 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 shal
34、l be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 6) All users should ensure that they have the latest edition of this publication. 7) No liabi
35、lity 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 whatsoever, whether direct or indirect, or for costs (inclu
36、ding 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 publications is indispensable for the correct application of
37、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. International Standard IEC 60794-2-30 has been prepared by sub-committee
38、86A: Fibres and cables, of IEC technical committee 86: Fibre optics. This second edition cancels and replaces the first edition published in 2003. It constitutes a technical revision. The main changes are listed below: a) subclause 5.4 has been detailed according to the fibre type; b) Annex A has be
39、en added to show an example of cable construction; c) Annex B has been added which is a blank detail specification including Mice classification and requirements; d) a bibliography has been added. This standard shall be used in conjunction with IEC 60794-1-1 and IEC 60794-1-2, and IEC 60794-2. 60794
40、2-30 IEC:2008 5 This bilingual version (2013-01) corresponds to the monolingual English version, published in 2008-10. The text of this standard is based on the following documents: FDIS Report on voting 86A/1233/FDIS 86A/1244/RVD Full information on the voting for the approval of this standard can
41、 be found in the report on voting indicated in the above table. The French version of this standard has not been voted upon. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts of IEC 60794 series, published under the general title Optical fibre c
42、ables, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the maintenance result date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication w
43、ill be reconfirmed, withdrawn, replaced by a revised edition, or amended. 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 docum
44、ent using a colour printer. 6 60794-2-30 IEC:2008 OPTICAL FIBRE CABLES Part 2-30: Indoor cables Family specification for ribbon cables 1 Scope This part of IEC 60794 is a family specification which covers optical fibre ribbon cables for indoor use. The requirements of the sectional specification IEC
45、 60794-2 are applicable to cables covered by this standard. Clause B.2 contains requirements that supersede the normal requirements in case the cables are intended to be used in installations governed by the MICE table of ISO/IEC 24702. 2 Normative references The following referenced documents are i
46、ndispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. These documents complete the normative references already listed in the generic specifica
47、tion (IEC 60794-1-1, Clause 2, and IEC 60794-1-2, Clause 2) or in the sectional specification (IEC 60794-2, Clause 2).
