IEC 62343-2:2014

Dynamic modules - Part 2: Reliability qualification

IEC 62343-2:2014 applies to dynamic modules and devices (DMs) which are commercially available. Examples are tuneable chromatic dispersion compensators, wavelength selective switches and optical channel monitors. Optical amplifiers are not included in this list, but are treated in IEC 61291-5-2. For reliability qualification purposes, some information about the internal components, parts and interconnections is needed; these internal parts are treated as black boxes. This standard gives requirements for the evaluation of DM reliability by combining the reliability of such internal black boxes. The objectives of this standard are the following:
- to specify the requirements for the reliability qualification of DMs;
- to give the minimum list of reliability qualification tests, requirements on failure criteria during testing and on reliability predictions, and give the relevant normative references. This second edition cancels and replaces the first edition published in 2011 and constitutes a technical revision. The main change with respect to the previous edition is the addition of Annex A (informative), Reliability test items and their conditions. Keywords: dynamic modules and devices (DMs), tuneable chromatic dispersion compensators, wavelength selective switches, optical channel monitors

Modules dynamiques - Partie 2: Qualification de fiabilité

L'IEC 62343-2:2014 s'applique aux dispositifs et aux modules dynamiques disponibles sur le marché. Les exemples suivants peuvent être donnés:
- compensateurs de dispersion chromatique accordables,
- commutateurs sélectifs en longueur d'onde et
- contrôleurs de canal de transmission optique. Les amplificateurs optiques ne sont pas inclus dans cette liste, mais ils sont traités dans l'IEC 61291-5-2. Dans le cadre de la qualification de fiabilité, certaines informations sur les composants, les constituants et les interconnexions internes sont nécessaires; ces constituants internes sont traités comme des boîtes noires. La présente norme donne les exigences pour l'évaluation de la fiabilité des modules dynamiques en combinant la fiabilité de telles boîtes noires internes. Les objectifs de la présente norme sont les suivants:
- spécifier les exigences pour la qualification de fiabilité des modules dynamiques;
- donner la liste minimale des essais de qualification de fiabilité, les exigences concernant les critères de défaillance pendant un essai et les prévisions de fiabilité, et donner les références normatives appropriées. Cette deuxième édition annule et remplace la première édition parue en 2011 et constitue une révision technique. La principale modification par rapport à l'édition précédente consiste en l'ajout de l'Annexe A (informative), Eléments d'essai de fiabilité et leurs conditions. Mots clés: dispositifs et aux modules dynamiques, compensateurs de dispersion chromatique accordables, commutateurs sélectifs en longueur d'onde, canal de transmission optique.

Part 2: Reliability qualification

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 thi
