16、TERFACES Part 20: Type LC connector family 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
17、questions concerning 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 Publica
18、tion(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, governmental and non- governmental organizations liaising with the IEC also participate in this preparation. IEC
19、 collaborates closely 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 opi
20、nion 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 international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to
21、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 promote international uniformity, IEC National Committees undertake to apply IEC Publications transparentl
22、y 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 indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certific
23、ation 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. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall
24、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 damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal
25、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 publication. Use of the referenced publications is indispensable for the correct application of this public
26、ation. International Standard IEC 61754-20 has been prepared by subcommittee SC86B: Fibre optic interconnecting devices and passive components. This second edition cancels and replaces the first edition published in 2002. It constitutes a technical revision. The changes with respect to the previous
27、edition are to reconsider the whole document and to add Interface IEC 61754-20-9 to IEC 61754-20-16 for a plastic optical fibre (POF). 4 61754-20 IEC:2012(E) The text of this standard is based on the following documents: FDIS Report on voting 86B/3343/FDIS 86B/3393/RVD Full information on the voting
28、 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. The list of all parts of IEC 61754 series, published under the general title, Fibre optic interconnecting and pas
29、sive components Fibre optic connector interfaces can be found on the IEC website. Future standards in this series will carry the new general title as cited above. Titles of existing standards in this series will be updated at the time of the next edition. The committee has decided that the contents
30、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 be reconfirmed, withdrawn, replaced by a revised edition, or amended. A bilingual version
31、 of this publication may be issued at a later date. 61754-20 IEC:2012(E) 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 61754-20.

36、ormative 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 (including any amendmen
37、ts) applies. IEC 61755-3 series, Fibre optic interconnecting devices and passive components Fibre optic connector optical interfaces 3 Description The parent connector for type LC connector family is a simplex plug connector set of plug/adaptor/plug configuration which is characterized by: A 1,25 mm
38、 nominal diameter ferrule or, in the case of 1 mm OD POF, the fibre acts as the ferrule. The connector includes a single coupling latch and a ferrule spring loaded in the direction of the optical axis The plug has a single male key, which may be used to orient and limit the relative position between
39、 the connector and the component to which it is mated. The optical alignment mechanism of the connectors is a rigid bore sleeve or a resilient sleeve. Drawings and dimensions provided consist of those minimum features that are functionally critical during the mating and unmating sequences of the plu
40、g with its adapter/receptacle counterpart component. The provided dimensions might cause intermateability problems with plugs not compliant to the standard. 4 Interfaces This standard contains the following standard interfaces: Interface 20-1: simplex plug connector interface PC Interface 20-2: simp
