20、rt 1: Generic specification 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 questions conce

21、rning 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 Publication(s)”). Thei

22、r 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 collaborates c

23、losely 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 opinion on the rel

24、evant 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 ensure that the

25、 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 transparently to the maximu

26、m 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 certification bodies pr

27、ovide 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 attach to IEC o

28、r 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 fees) and expen

29、ses 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 publication. 9) Atten

30、tion is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC 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 interconnecti

31、ng devices and passive components, of IEC technical committee 86: Fibre optics. This fourth edition cancels and replaces the 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

32、) the terms and definitions were reconsidered; b) quality assessment level was deleted from classification; c) the clause numbers of Annexes A and B have been rearranged. IEC 61202-1:2016 IEC 2016 5 The text of this International Standard is based on the following documents: CDV Report on voting 86B

33、/3989A/CDV 86B/4033RVC Full information on the voting for the approval of this International Standard can 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, publ

34、ished under the general title Fibre optic interconnecting devices and passive components Fibre optic isolators, 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 tha

35、t it contains colours which are considered to be useful for the correct understanding of its contents. Users should therefore print this document using a colour printer. 6 IEC 61202-1:2016 IEC 2016 FIBRE OPTIC INTERCONNECTING DEVICES AND PASSIVE COMPONENTS FIBRE OPTIC ISOLATORS Part 1: Generic speci

36、fication 1 Scope This part of IEC 61202 applies to isolators used in the field of fibre 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-electron

37、ic or other transducing elements; they have two optical ports for directionally transmitting 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.
