22、ES AND PASSIVE COMPONENTS FIBRE OPTIC CONNECTOR INTERFACES Part 26: Type SF 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 IE
23、C is to promote international co-operation on all 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)
24、 and Guides (hereafter referred to as “IEC Publication(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
25、the IEC also participate in this preparation. IEC 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 near
26、ly as possible, an international consensus of opinion 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
27、 sense. While all reasonable efforts are made to 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
28、 undertake to apply IEC Publications transparently 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 an
29、y attestation of conformity. Independent certification 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 ed
30、ition 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 for any personal injury, property damage or other damage of any nature whatsoever, whether d
31、irect 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 Normative references cited in this publication. Use of the referenced publications is indispe
32、nsable for the correct application of this publication. International Standard IEC 61754-26 has been prepared by subcommittee 86B: 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: FD
33、IS Report on voting 86B/3433/FDIS 86B/3468/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. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2, A list of all parts of the IEC 61754
34、 series, under the general title Fibre optic connector interfaces, can be found on the IEC website. 4 61754-26 IEC:2012 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 co
35、mmittee 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 be reconfirmed, withdrawn, replaced by a revised ed
36、ition, or amended. 61754-26 IEC:2012 5 INTRODUCTION The International Organization for 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 61754-26. IEC takes no position conc
37、erning the evidence, validity and scope of this patent right.

39、rights other than those identified above. IEC shall not be held responsible for identifying any or all such patent rights. 6 61754-26 IEC:2012 FIBRE OPTIC INTERCONNECTING DEVICES AND PASSIVE COMPONENTS FIBRE OPTIC CONNECTOR INTERFACES Part 26: Type SF connector family 1 Scope This part of IEC 61754
40、defines the standard interface dimensions for the type SF optical board connector that uses a normal glass fibre and the physical contact technique to connect flexible optical boards and ribbon fibres. 2 Description The parent connector for the type SF connector family is a multiway connector with a
41、 plug/socket connector set configuration, The plug is characterized by multiway cantilevered optical fibres located inside the plug, The plug optical fibres buckled to mate with the socket optical fibre ends, Mating socket optical fibres are positioned and aligned by using multiway micro holes, Sock
42、et micro holes capture, guide, and align the plug optical fibres during connector set engagement, The plug fibres and socket fibres are butted together to realize physical contact connection by employing the buckled force of the plug fibres without using a ferrule or a spring, 3 Interfaces This stan
43、dard contains the following standard interfaces, IEC 61754-26-1: SF plug connector flat interface for 2 to 16 fibres IEC 61754-26-2: SF socket connector flat interface for 2 to 16 fibres The following connectors are intermateable: IEC 61754-26-1 mates with IEC 61754-26-2 Figure 1 is an example of a
