IEC 62572-3:2011

Fibre optic active components and devices - Reliability standards - Part 3: Laser modules used for telecommunication

IEC 62572-3:2011 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 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.

Composants et dispositifs actifs en fibres optiques - Normes de fiabilité - Partie 3: Modules laser utilisés pour les télécommunications

La CEI 62572-3:2011 s'applique à l'évaluation de la fiabilité des modules laser utilisés pour les télécommunications. La présente norme a pour objet:
- d'établir une méthode normalisée permettant d'évaluer la fiabilité des modules laser afin de minimiser les risques et de favoriser le développement et la fiabilité des produits;
- d'établir des moyens permettant de déterminer la répartition des défaillances au fil du temps. Ceci devrait permettre de déterminer les taux de défaillance du matériel pour les critères de fin de vie spécifiés.

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 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
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 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 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 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 promote 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 indicated 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) All 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 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 publication. 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 patent rights.
International Standard IEC 62572-3 has been prepared by subcommittee 86C: Fibre optic

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).

For the system operator to act as an informed buyer, knowledge of the potential risks posed

by the use of critical components is required.

Optoelectronic component technology is continuing to develop. Consequently, during product

development phases, many failure mechanisms in laser modules have been identified. These

failure mechanisms, if undetected, could result in very short laser lifetime i
