Dynamic modules - Part 2: Reliability qualification (IEC 62343-2:2011)
This part of IEC 62343 applies to dynamic modules and devices (DMs) which are commercially available. Examples are tuneable chromatic dispersion compensators, reconfigurable optical cross-connects, and dynamic channel equalizers. (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 part of IEC 62343 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.
Dynamische Module - Teil 2: Beurteilung der Zuverlässigkeit (IEC 62343-2:2011)
Modules dynamiques - Partie 2: Qualification de fiabilité (CEI 62343-2:2011)
La CEI 62343-2:2011 s'applique aux dispositifs et aux modules dynamiques (DM: Dynamic Module) disponibles dans le commerce. Des exemples sont les compensateurs de dispersion chromatique accordables, les brasseurs optiques reconfigurables et les égaliseurs de voies dynamiques. (Les amplificateurs optiques ne sont pas inclus dans cette liste, mais ils sont traités dans la CEI 61291-5-2). Dans le cadre de la qualification de fiabilité, certaines informations sur les interconnexions, les pièces et les composants internes sont nécessaires. Ces pièces internes sont traitées 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.
Dinamični moduli - 2. del: Kvalifikacije zanesljivosti (IEC 62343-2:2011)
Ta del IEC 62343 velja za dinamične module in naprave (DM), ki so na voljo na tržišču. Primeri so nastavljivi kompenzatorji za kromatično disperzijo, optični prevezovalni sistemi z zmožnostjo preoblikovanja in dinamični kanalski stabilizatorji. (Optični ojačevalniki niso zajeti na tem seznamu, ampak so obravnavani v IEC 61291-5-2). Za namene zanesljivosti kvalifikacije je potrebnih nekaj podatkov o notranjih komponentah, sestavnih delih in medsebojnih povezavah; ti notranji sestavni deli se obravnavajo kot črna skrinjica. Ta standard podaja zahteve za vrednotenje zanesljivosti DM s kombiniranjem zanesljivosti takih notranjih črnih skrinjic. Cilji tega dela IEC 62343 so: ? opredeliti zahteve za kvalifikacijo zanesljivosti naprav DM; podati minimalni seznam preskusov kvalifikacije zanesljivosti, zahtev glede meril za okvare med preskušanjem in napovedi zanesljivosti, in podajajo ustrezne normativne sklice.

DYNAMIC MODULES –
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 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 62343-2 has been prepared by subcommittee 86C: Fibre optic
systems and active devices, of IEC technical committee 86: Fibre optics.
The text of this standard is based on the following documents:

DYNAMIC MODULES –
Part 2: Reliability qualification
1 Scope
This part of IEC 62343 applies to dynamic modules and devices (DMs) which are
commercially available. Examples are tuneable chromatic dispersion compensators,
reconfigurable optical cross-connects, and dynamic channel equalizers. (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 part of IEC 62343 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.

3 Terms, definitions and abbreviations
3.1 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1.1
failure
non-compliance to product specification or change in parameters as set by the standard or
agreed by the customer and supplier
3.1.2
qualification
commonly used as the abbreviation for Reliability Qualification. It is used as a formal testing
to determine whether or not the product is suitable for telecom applications and therefore,
“pass or fail” is the expected outcome
NOTE This is different from reliability test, which is in nature a reliability “engineering test”. Reliability tests are
designed to understand the reliability consideration or estimate the reliability of the product. Pass or fail is not the
main output.
3.1.3
reliability
There are two common uses of this term:
a) minimum period of DM continuous operation without failure at specified operating and
environmental conditions
b) probability to perform required functions at specified operating and environmental
conditions
NOTE The reliability of a DM is expressed by either of the following two parameters: mean time between failure
(MTBF) and failures in time (FIT):
• The MTBF is the mean period of DM continuous operation without any failure at specified operating and
environmental conditions.
9
• The FIT is the number of failures expected in 10 device-hours at specified operating and environmental
conditions.
3.2 Abbreviated terms
Each abbreviation introduced in this International Standard is explained in the text at least the
first time it appears. However, for an easier understanding of the whole text, the following is a
list of all abbreviations used in this International Standard:

4 Reliability qualification considerations
4.1 General
Since DMs are relatively new products in the commercial market and involve different
technologies, the requirements included in this standard will need to be reviewed as
technology progresses.
4.2 General consideration approach
It is worth emphasizing the fundamental approach of reliability qualification adopted in this
standard:
a) Any parts that can be effectively qualified on their individual levels must be qualified at
that level. Their qualification shall be based on IEC standards or other industrial standards
in the absence of such IEC standards.
b) The qualification tests required at DM level must be based on the degradation
mechanisms and failure modes that cannot be effectively detected in the lower part levels.
At the DM level, the qualification tests shall not attempt to discover or identify those
degradation mechanisms and failure modes that can be discovered in the lower assembly
levels than the final product level. For example, if all parts in the DM can be effectively
tested for damp heat-accelerated degradations, there is no need to repeat the damp heat
test at the DM level.
4.3 DM product design
A DM is an assembly of various components, parts, and interconnections. There are two basic
designs in the current commercial DM market:
a) Design 1: Parts (as a general term that includes components, parts and interconnections
used to build a DM from this point on for this standard) are packaged separately. Their
packages are usually either hermetic or moisture-resistant. They are integrated into a
housing (usually non-hermetic or not moisture-resistant).
b) Design 2: Some parts used in DMs are unpackaged basic optical elements (e.g. crystals,
lenses, mirrors, etc.). These parts cannot be effectively qualified by themselves. These
parts/elements are integrated and packaged inside a hermetic box or moisture-resistant
box.
In Design 1, the individual parts can be tested and qualified individually and therefore, the DM
qualification does not have to repeat the tests that are performed in the part levels for the
same degradation mechanisms and failure modes.
In Design 2, the DM qualification is again focused on the tests that cannot be effe
...
