25、VE COMPONENTS BASIC TEST AND MEASUREMENT PROCEDURES Part 3-21: Examinations and measurements Switching time FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). T
26、he 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 publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Speci
27、fications (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 participate in this preparatory work. International, governmental and non- governmental organization
28、s 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 between the two organizations. 2) The formal decisions or agreements of IEC on technical matters
29、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 Publications have the form of recommendations for international use and are accepted by IEC National Co
30、mmittees 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 any misinterpretation by any end user. 4) In order to promote international uniformity, IEC Nat
31、ional 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 corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself doe
32、s 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 services carried out by independent certification bodies. 6) All users should ensure that they ha
33、ve 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 National Committees for any personal injury, property damage or other damage of any nature whats
34、oever, 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) Attention is drawn to the Normative references cited in this publication. Use of the referenced publica
35、tions 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 shall not be held responsible for identifying any or all such patent rights. International Stand
36、ard IEC 61300-3-21 has been prepared by subcommittee 86B: Fibre optic interconnecting devices and passive components, of IEC technical committee 86: Fibre optics. This second edition cancels and replaces the first edition published in 1998. This edition constitutes a technical revision. This edition
37、 includes the following significant technical changes with respect to the previous edition: a) removal of “bounce time” from the title; b) update and alignment of definitions with IEC 60876-1; c) generalization of the detection apparatus beyond an oscilloscope. 4 IEC 61300-3-21:2014 IEC 2014 The tex
38、t of this standard is based on the following documents: CDV Report on voting 86B/3623/CDV 86B/3702/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/IEC
39、Directives, Part 2. A list of all parts in the IEC 61300 series, published under the general title, Fibre optic interconnecting devices and passive components Basic test and measurement procedures, can be found on the IEC website. The committee has decided that the contents of this publication will
40、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. IEC 61300-3-21:2014 IEC 2014 5 FIBRE OPTIC I
41、NTERCONNECTING DEVICES AND PASSIVE COMPONENTS BASIC TEST AND MEASUREMENT PROCEDURES Part 3-21: Examinations and measurements Switching time 1 Scope This part of IEC 61300 is a method to measure the switching time and related performance parameters of an optical switch when the actuation energy is ap
