32、 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 activities, IEC publish
33、es 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 dealt with may par
34、ticipate 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 determined by agreement b
35、etween 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 Committees. 3) IEC Publica
36、tions 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 they are used or for
37、 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 and the correspond
38、ing 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 responsible for any s
39、ervices 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 committees and IEC
40、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 Publications. 8) Attenti
41、on 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 patent rights. IEC
42、shall not be held responsible for identifying any or all such patent rights. International Standard IEC 61202-1 has been prepared by subcommittee 86B: Fibre optic interconnecting devices and passive components, of IEC technical committee 86: Fibre optics. This fourth edition cancels and replaces the
43、 third edition published in 2009. It constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) the terms and definitions were reconsidered; b) quality assessment level was deleted from classification; c) the clause nu
44、mbers of Annexes A and B have been rearranged. BS EN 61202-1:2017IEC 61202-1:2016 IEC 2016 5 The text of this International Standard is based on the following documents: CDV Report on voting 86B/3989A/CDV 86B/4033RVC Full information on the voting for the approval of this International Standard can
45、be found in the report on voting indicated in the above table. This document has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts in the IEC 61202 series, published under the general title Fibre optic interconnecting devices and passive components Fibre optic isola
46、tors, can be found on the IEC website. A bilingual version of this publication may be issued at a later date. IMPORTANT The colour inside logo on the cover page of this publication indicates that it contains colours which are considered to be useful for the correct understanding of its contents. Use
47、rs should therefore print this document using a colour printer.

48、 optics, all exhibiting the following features: they are non-reciprocal optical devices, in which each port is either an optical fibre or fibre optic connector; they are passive devices containing no opto-electronic or other transducing elements; they have two optical ports for directionally transmi
49、tting optical power. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.
