21、for use in premises cabling FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions conce

22、rning 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 Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Thei

23、r 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 liaising with the IEC also participate in this preparation. IEC collaborates cl

24、osely 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 express, as nearly as possible, an international consensus of opinion on the rele

25、vant 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 Committees in that sense. While all reasonable efforts are made to ensure that the

26、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 National Committees undertake to apply IEC Publications transparently to the maximum

27、 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 not provide any attestation of conformity. Independent certification bodies pro

28、vide 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 the latest edition of this publication. 7) No liability shall attach to IEC or

29、 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 (including legal fees) and expens

30、es 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 this publication. 9) Attent

31、ion 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 60794-2-31 has been prepared by subcommittee 86A: Fibres and cables, of I

32、EC technical committee 86: Fibre optics. This second edition cancels and replaces the first edition published in 2005. It constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: incorporation of the OM4 cabled fibre pe

33、rformance category; incorporation of the OS2 cabled fibre performance category; incorporation of the B6_a1 and B6_a2 fibre categories as per IEC 60793-2-50. 4 60794-2-31 IEC:2012 The text of this standard is based on the following documents: FDIS Report on voting 86A/1468/FDIS 86A/1484/RVD Full info

34、rmation on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all the parts in the IEC 60794 series, published under the general title Optical f

35、ibre cables, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until 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

36、 be reconfirmed, withdrawn, replaced by a revised edition, or amended.

38、to ensure compatibility with ISO/IEC 11801. The requirements of the family specification IEC 60794-2-30 are applicable to cables covered by this standard. The particular requirements detailed in Clause 4 either define a specific option relative to the requirements of IEC 60794-2-30 or define additio

39、nal requirements. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (i

40、ncluding any amendments) applies. NOTE They complete the normative references already listed in the generic specification (IEC 60794-1-11 1and IEC 60794-1-2) and in the sectional specification (IEC 60794-2 2) or in the family specification (IEC 60794-2-30).
