familyFOREWORD1)The International Electrotechnical Commission(IEC)is a worldwide organization for standardization comprisingall national electrotechnical committees(IEC National Committees).The object of IEC is to promoteinternational co-operation on all questions concerning standardization in the electrical and electronic fields.Tothis end and in addition to other activities,IEC publishes International Standards,Technical SpecificationsTechnical Reports,Publicly Available Specifications(PAS)and Guides(hereafter referred to as IECPublication(s).Their preparation is entrusted to technical committees;any IEC National Committee interestedin 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 closelywith the International Organization for Standardization(ISO)in accordance with conditions determined byagreement between the two organizations.2)The formal decisions or agreements of IEC on technical matters express,as nearly as possible,an internationalconsensus of opinion on the relevant subjects since each technical committee has representation from allinterested IEC National Committees.3)IEC Publications have the form of recommendations for international use and are accepted by IEC NationalCommittees in that sense.While all reasonable efforts are made to ensure that the technical content of IECPublications is accurate,IEC cannot be held responsible for the way in which they are used or for anymisinterpretation by any end user.4)In order to promote international uniformity,IEC National Committees undertake to apply IEC Publicationstransparently to the maximum extent possible in their national and regional publications.Any divergencebetween any IEC Publication and the corresponding national or regional publication shall be clearly indicated inthe latter.5)IEC itself does not provide any attestation of conformity.Independent certification bodies provide conformityassessment services and,in some areas,access to IEC marks of conformity.IEC is not responsible for anyservices 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 its directors,employees,servants or agents including individual experts andmembers of its technical committees and IEC National Committees for any personal injury,property damage orother damage of any nature whatsoever,whether direct or indirect,or for costs(including legal fees)andexpenses arising out of the publication,use of,or reliance upon,this IEC Publication or any other IECPublications.8)Attention is drawn to the Normative references cited in this publication.Use of the referenced publications isindispensable 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 ofpatent rights.IEC shall not be held responsible for identifying any or all such patent rights.International Standard IEC 61754-31 has been prepared by subcommittee 86B:Fibre opticinterconnecting devices and passive components,of IEC technical committee 86:Fibre optics.The text of this standard is based on the following documents:FDISReport on voting86B/3961/FDIS86B/3973/RVDFull information on the voting for the approval of this standard can be found in the report onvoting indicated in the above table.This
