28、D 1) The International Electrotechnical Commission (IEC) is a worldwide organisation for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electr

29、ical 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)”). Their preparation is entrusted to techn

30、ical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non- governmental organisations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organ

31、isation for Standardization (ISO) in accordance with conditions determined by agreement between the two organisations. 2) The formal 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

32、 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 technical content of IEC Publicati

33、ons 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 extent possible in their national

34、 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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in

35、 conformity with an IEC Publication. 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

36、for any personal injury, property damage 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 N

37、ormative references cited in this publication. 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 re

38、sponsible for identifying any or all such patent rights. International Standard IEC 61758-1 has been prepared by subcommittee 86B: Fibre optic interconnecting devices and passive components, of IEC technical committee 86: Fibre optics. This bilingual version (2012-09) corresponds to the monolingual

39、English version, published in 2008-04. The text of this standard is based on the following documents: FDIS Report on voting 86B/2683/FDIS 86B/2712/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. The French versio

40、n of this standard has not been voted upon. 61758-1 IEC:2008 5 This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts of the IEC 61758 series, published under the general title Fibre optic interconnecting devices and passive components Interface stan

41、dard for closures, 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 p

42、ublication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 6 61758-1 IEC:2008 FIBRE OPTIC INTERCONNECTING DEVICES AND PASSIVE COMPONENTS INTERFACE STANDARD FOR CLOSURES Part 1: General and guidance 1 Scope This part of IEC 61758 provides general information and guidance on

43、 the subject of closures. It includes references, general closure and interface descriptions and definitions. This standard defines the following general interfaces for closures: interface to cables; interface to FMS; interface to parts other than FMS or cables; interface to external sitings (pits,

44、manholes etc.) This specification covers all types of closures. The performance requirements are given in IEC 61753-111 series (in preparation). This closure standard allows both single mode and multi-mode fibre to be used, and covers all IEC standard optical fibre cables as listed in Clause 2, with

45、 their various fibre capacities, types and designs. Figure 1 shows and defines the interface between the closure and the fibre management system. 61758-1 IEC:2008 7 a f c e b d m k p k n h g Fibre management system* Closure* j IEC 532/08 Key Closure functions* (a) Cable sealing (b) Cable anchorage (
