21、 IEC:2011 3 INTERNATIONAL ELECTROTECHNICAL COMMISSION _ OPTICAL AMPLIFIERS Part 4: Multichannel applications Performance specification template FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical com
22、mittees (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 publishes International Standards, Technical Specifications, Technic
23、al 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 participate in this preparatory work. International, governmenta
24、l 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 between the two organizations. 2) The formal decisions or agre
25、ements 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 Publications have the form of recommendations for international use
26、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 any misinterpretation by any end user. 4) In order to promot
27、e 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 corresponding national or regional publication shall be clearly indicat
28、ed 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 services carried out by independent certification bodies. 6) A
29、ll 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 National Committees for any personal injury, property damage
30、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) Attention is drawn to the Normative references cited in this publica
31、tion. 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 shall not be held responsible for identifying any or all such
32、 patent rights. International Standard IEC 61291-4 has been prepared by subcommittee 86C: Fibre optic systems and active devices, of IEC technical committee 86: Fibre optics. This third edition cancels and replaces the second edition published in 2008 and constitutes a technical revision. The main s
33、ignificant changes are the following: The transient parameter test methods, IEC 61290-4 series, have been added to Tables 1, 2, and 3. 4 61291-4 IEC:2011 The text of this standard is based on the following documents: CDV Report on voting 86C/993/CDV 86C/1024/RVC Full information on the voting for th
34、e 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. This standard is to be used in conjunction with IEC 61291-1. A list of all parts in the IEC 61291 series, published unde
35、r the general title Optical amplifiers, can be found on the IEC website. The committee 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
36、 date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 61291-4 IEC:2011 5 INTRODUCTION This International Standard is devoted to the subject of optical amplifiers. The technology of optical amplifiers is still rapidly evolving, hence amendments and new edit
37、ions to this standard can be expected. Each abbreviation introduced in this International Standard is generally explained in the text the first time it appears. However, for an easier understanding of the whole text, a list of abbreviations used in this International Standard is given in 3.3. 6 6129
38、1-4 IEC:2011 OPTICAL AMPLIFIERS Part 4: Multichannel applications Performance specification template 1 Scope This part of IEC 61291 applies to optical amplifier (OA) devices and sub-systems to be used in multichannel applications. For single channel applications, use IEC 61291-2. The object of this
39、performance specification template is to provide a frame for the preparation of detail specifications on the performances of OA devices and sub-systems to be used in multichannel applications. Detail product specification writers may add specification parameters and/or groups of specification parame
40、ters for particular applications. However, detail specification writers may not remove specification parameters specified in this standard. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For
41、dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

43、Terms and definitions For the purposes of this document, the terms, definitions and parameters given in IEC 61291-1 and the following apply. 3.2 Overview of multichannel definitions Parameters specified for optical devices are those characterizing the transmission, operation, reliability and environ
44、mental properties of the OA device, which is seen as a black box from a general point of view as defined in the generic specification IEC 61291-1. Each test method (OA test methods, IEC 61290 series) is generally given for the measurement of a group of homogeneous parameters. The grouping of the hom
45、ogeneous parameters is 61291-4 IEC:2011 7 given in the generic specification, IEC 61291-1, together with the corresponding test method specification number. Safety characteristics of optical amplifiers described in the present standard are provided in IEC 60825-1. A typical configuration of an OA in
