21、 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. To this end and in addition to other activi
22、ties, 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 National Committee interested in the subject d
23、ealt 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 (ISO) in accordance with conditions determi
24、ned 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 representation from all interested IEC National Committe
25、es. 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 be held responsible for the way in which th
26、ey 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. Any divergence between any IEC Publication
27、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 to IEC marks of conformity. IEC is not res
28、ponsible 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 individual experts and members of its technical c
29、ommittees 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, this IEC Publication or any other IEC Public
30、ations. 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. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of p

International Standard IEC 61754-1 has been prepared by subcommittee SC86B: Fibre optic interconnecting devices and passive components, of IEC technical committee 86: Fibre optics. This second edition canc
32、els and replaces the first edition, published in 1996, and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) general reconsideration of performance requirements; b) addition of Figure 1. 4 61754-1 IEC:2013 The
33、 text of this standard is based on the following documents: CDV Report on voting 86B/3503/CDV 86B/3602/RVC 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/
34、IEC Directives, Part 2. A list of all parts in the IEC 61754 series, published under the general title, Fibre optic interconnecting devices and passive components Fibre optic connector interfaces, can be found on the IEC website. The committee has decided that the contents of this publication will r
35、emain 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. 61754-1 IEC:2013 5 INTRODUCTION An optical co
36、nnector interface is a collection of physical features on a connector assembly that defines a specified style. It consists of those minimum features that are functionally critical (i.e. work together) during the mechanical mating and unmating sequences of the connector with its counterpart component
37、. The interface defines the size, relative location and tolerance for each of the features. In addition, it defines the location for the optical datum target. This part of IEC 61754 contains those interfaces that have been standardized for international use. It consists of individual sets of plug an
38、d adaptor interfaces. Each set contains at least two counterpart interfaces that mate together. The standards therefore only ensure that the two counterpart interfaces will mate together and that they will mate with a specified fit tolerance between the mating features. It is important to emphasize
39、that the standard interfaces define physical dimensions only and that no guarantee of performance is implied, nor should be assumed, for connectors that comply with the standards. Manufacturers using the standards are responsible for positioning the optical fibre or device port at the optical datum
40、target location with the accuracy necessary to meet their required performance. An optical connector, by definition, mates with another optical component. Typically, the mating component is another optical connector. In many cases, however, the mating component is not another connector but rather an
41、 optical component such as a switch, a branching device or an active device. The portion of the component that contains the mating features to receive and position the connector is called an adaptor. This standard makes a distinction between a connector interface and an adaptor interface. An adaptor
42、 interface may not contain an optical datum target as in the case where two connector plugs are engaged and are aligned by an alignment sleeve. However, the adaptor does contain an optical datum target whenever it positions an optical fibre or optical fibre waveguide, as in an active device or branc
43、hing device. 6 61754-1 IEC:2013 FIBRE OPTIC INTERCONNECTING DEVICES AND PASSIVE COMPONENTS FIBRE OPTIC CONNECTOR INTERFACES Part 1: General and guidance 1 Scope This part of IEC 61754 covers general information on the subject of fibre optic connector interfaces.
