19、ROTECHNICAL COMMISSION _ FIBRE OPTIC ACTIVE COMPONENTS AND DEVICES RELIABILITY STANDARDS Part 3: Laser modules used for telecommunication FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committee

20、s (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, Technical Rep

21、orts, 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, governmental and

22、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 agreements

23、 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 and ar

24、e 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 promote inte

25、rnational 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 indicated in

26、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) All use

27、rs 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 or oth

28、er 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 publication.

29、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 paten

30、t rights. International Standard IEC 62572-3 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 2014. This third edition constitutes a technical revision in

31、 which errors in Table 1 and Table 2 have been corrected. The text of this standard is based on the 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.

32、4 IEC 62572-3:2016 IEC 2016 This publication has been drafted in accordance with 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 commit

33、tee has decided that the contents of this publication will remain unchanged until 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

34、, or amended. A bilingual version of this publication may be issued at a later date. IEC 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 opera

35、tor (SO) or a network operator (see definitions in Clause 3). 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 d

36、evelopment phases, many failure mechanisms in laser modules have been identified. These failure mechanisms, if undetected, could result in very short laser lifetime in system use. 6 IEC 62572-3:2016 IEC 2016 FIBRE OPTIC ACTIVE COMPONENTS AND DEVICES RELIABILITY STANDARDS Part 3: Laser modules used f

37、or telecommunication 1 Scope This part of 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 an

38、d reliability; to establish means by which 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, i
