27、ATIONAL ELECTROTECHNICAL COMMISSION _ OPTICAL FIBRE CABLES Part 2-10: Indoor optical fibre cables Family specification for simplex and duplex cables FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnica
28、l 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 Specifications, Te
29、chnical 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. International, govern
30、mental 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 formal decisions o
31、r 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 for internationa
32、l 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) In order to
33、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 shall be clearly i
34、ndicated in the latter. 5) IEC itself does not 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
35、 6) All users should ensure that they have the 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 d
36、amage or other damage of any nature whatsoever, 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 p
37、ublication. Use of the referenced publications 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 al
38、l such patent rights. International Standard IEC 60794-2-10 has been prepared by sub-committee 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 with
39、 respect to the previous edition are as follows: A new clause has been introduced: Clause 4 Dimensions. Test conditions and requirements have been made more accurate. The new Subclause 5.5 has been added to give useful figures. This standard is to be used in conjunction with IEC 60794-1-1:2008, IEC
40、60794-1-2:2007 and IEC 60794-2. 60794-2-10 IEC:2011 5 The text of this standard is based on the following documents: FDIS Report on voting 86A/1396/FDIS 86A/1412/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. Th
41、is 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 cables, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged u
42、ntil the stability 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 will be reconfirmed, withdrawn, replaced by a revised edition, or amended. IMPORTANT The colour inside logo on the cover page of this pub
43、lication indicates that it contains colours which are considered to be useful for the correct understanding of its contents. Users should therefore print this document using a colour printer. 6 60794-2-10 IEC:2011 OPTICAL FIBRE CABLES Part 2-10: Indoor optical fibre cables Family specification for s
44、implex and duplex cables 1 Scope This part of IEC 60794 is a family specification that covers simplex and duplex optical fibre cables for indoor use except for cables used in terminated assemblies specified by IEC 60794-2-50. The requirements of the Sectional specification IEC 60794-2 are applicable
45、 to cables covered by this standard. For the cables intended for installation in industrial applications specified in ISO/IEC 24702, MICE specifications may be additionally required (see Annex B.2). 2 Normative references The following referenced documents are indispensable for the application of th
46、is document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. NOTE 1 They complete the normative references already listed in the generic specification (IEC 60794-1-1, Clause 2, and IEC 607
