30、Laser modules used for telecommunication 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 qu
31、estions 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 Specifications (PAS) and Guides (hereafter referred to as “IEC Publicati
32、on(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 organizations liaising with the IEC also participate in this preparation. IEC co
33、llaborates 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 express, as nearly as possible, an international consensus of opinio
34、n 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 Committees in that sense. While all reasonable efforts are made to ens
35、ure 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 National Committees undertake to apply IEC Publications transparently t
36、o 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 does not provide any attestation of conformity. Independent certificati
37、on 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 have the latest edition of this publication. 7) No liability shall att
38、ach 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 whatsoever, whether direct or indirect, or for costs (including legal fee
39、s) 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 publications is indispensable for the correct application of this publicati
40、on. 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 Standard IEC 62572-3 has been prepared by subcommittee 86C: Fibre optic s
41、ystems and active devices of IEC technical committee 86: Fibre optics. This third edition cancels and replaces the second edition published in 2014. This third edition constitutes a technical revision in which errors in Table 1 and Table 2 have been corrected. The text of this standard is based on t
42、he following documents: CDV Report on voting 86C/1302/CDV 86C/1345/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. BS EN 62572-3:2016 4 IEC 62572-3:2016 IEC 2016 This publication has been drafted in accordance wi
43、th the ISO/IEC Directives, Part 2. A list of all parts in the IEC 62572 series, published under the general title Fibre optic active components and devices Reliability standards, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged un
44、til the stability date indicated on the IEC website 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. A bilingual version of this publication may be issued at a later
45、 date. BS EN 62572-3:2016IEC 62572-3:2016 IEC 2016 5 INTRODUCTION The laser modules covered by this International Standard are purchased by system suppliers (SS) to be inserted in equipment, which in turn are supplied/sold to a system operator (SO) or a network operator (see definitions in Clause 3)
46、. For the system operator to act as an informed buyer, he/she should have knowledge of the potential risks posed by the use of critical components. Optoelectronic component technology is continuing to develop. Consequently, during product development phases, many failure mechanisms in laser modules
47、have been identified. These failure mechanisms, if undetected, could result in very short laser lifetime in system use. BS EN 62572-3:2016 6 IEC 62572-3:2016 IEC 2016 FIBRE OPTIC ACTIVE COMPONENTS AND DEVICES RELIABILITY STANDARDS Part 3: Laser modules used for telecommunication 1 Scope This part of
48、 IEC 62572 deals with reliability assessment of laser modules used for telecommunication. The aim of this standard is to establish a standard method of assessing the reliability of laser modules in order to minimize risks and to promote product development and reliability; to establish means by whic
49、h the distribution of failures with time can be determined. This should enable the determination of equipment failure rates for specified end of life criteria. In addition, guidance is given in IEC TR 62572-2. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
