23、rotechnical 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 concerning standardization in the electrical and electronic fields.
24、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 technical committees; any IEC Nat
25、ional 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 closely with the International Organization for Standardization
26、(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 relevant subjects since each technical committee has representatio
27、n 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 Publications is accurate, IEC cannot
28、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 and regional publications.
29、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 provide conformity assessment services and, in some areas, access
30、 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 its directors, employees, servants or agents including indivi
31、dual 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 expenses arising out of the publication, use of, or reliance upon, t
32、his 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. International Standard IEC 61754-28 has been prepared by subcommittee 8
33、6B: Fibre optic interconnecting devices and passive components, of IEC technical committee 86: Fibre optics. The text of this standard is based on the following documents: FDIS Report on voting 86B/3387/FDIS 86B/3435/RVD Full information on the voting for the approval of this standard can be found i
34、n the report on voting indicated in the above table. A list of all the parts in the IEC 61754 series, under the general title Fibre optic interconnecting devices and passive components Fibre optic connector interfaces, can be found on the IEC website. 4 61754-28 IEC:2012 This publication has been dr
35、afted in accordance with the ISO/IEC Directives, Part 2. 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 publi
36、cation will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 61754-28 IEC:2012 5 INTRODUCTION The International Electrotechnical Commission (IEC) draws attention to the fact that it is claimed that compliance with this document may involve the use of a patent concerning IEC 6175
37、4-28. IEC takes no position concerning the evidence, validity and scope of this patent right. The holder of this patent right has assured the IEC that he/she is willing to negotiate licences under reasonable and non - discriminatory terms and conditions with applicants throughout the world. In this
38、respect, the statement of the holder of this patent right is registered with IEC. Information may be obtained from: DIAMOND SA Via dei Patrizi 5 6616 Losone Switzerland Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights other than tho
39、se identified above. IEC shall not be held responsible for identifying any or all such patent rights. ISO (www.iso.org/patents) and IEC (http:/www.iec.ch/tctools/patent_decl.htm) maintain on-line data bases of patents relevant to their standards. Users are encouraged to consult the data bases for th

41、nectors. 2 Normative reference 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 (including a
42、ny amendments) applies. IEC 60794-2-50, Optical fibre cables Part 2-50: Indoor cables Family specification for simplex and duplex cables for use in terminated cable assemblies 3 Description The parent connector for the type LF3 connector family is a simplex connector which is characterized by a 1,25
43、 mm nominal ferrule diameter. It includes a push-click-pull coupling mechanism, which is spring-loaded relative to the ferrule in the direction of the optical axis. The optical alignment mechanism of the connectors is a rigid bore sleeve or a resilient sleeve style. Drawings and dimensions provided
44、consist of those minimum features that are functionally critical during the mating and unmating sequences of the plug with its adapter/receptacle counterpart component. 4 Interfaces The pages that follow define the standard interfaces for the type LF3 connector family.
