Dynamic modules - General and guidance (IEC 62343:2017)
IEC 62343 applies to all commercially available optical dynamic modules and devices. It
describes the products covered by the IEC 62343 series, defines terminology, fundamental
considerations and basic approaches.
The object of this document is to
• establish uniform requirements for operation, reliability and environmental properties of
dynamic modules (DMs) to be implemented in the appropriate DM standard, and
• provide assistance to the purchaser in the selection of consistently high-quality DM
products for his particular applications, as well as in the consultation of the appropriate
specific DM standard(s).
This document covers performance templates, performance standards, reliability qualification
requirements, hardware and software interfaces and related testing methods.
Since a dynamic module integrates an optical module/device, printed wiring board, and
software/firmware, the standards developed in the series will mimic appropriate existing
standards. On the other hand, since "dynamic module" is a relatively new product category,
the dynamic module standards series will not be bounded by the existing practices where
requirements differ.
The safety standards as related to dynamic modules are mostly optical power considerations,
which is covered by IEC TC 76: Optical radiation safety and laser equipment.
Dynamische Module - Allgemeines und Leitfaden (IEC 62343:2017)
Modules dynamiques - Généralités et lignes directrices (IEC 62343:2017)
IEC 62343:2017 s’applique à tous les dispositifs et modules dynamiques optiques disponibles dans le commerce. Elle décrit les produits couverts par la série IEC 62343, définit la terminologie, les considérations fondamentales et les approches de base. Le présent document a pour objets:d’établir des exigences uniformes pour le fonctionnement, la fiabilité et les propriétés environnementales des modules dynamiques (DM) à intégrer dans la norme appropriée sur les modules dynamiques; et d’aider l’acheteur à choisir des produits à modules dynamiques de haute qualité dans le cadre de ses applications particulières et à consulter les normes appropriées sur les modules dynamiques spécifiques. Le présent document couvre les modèles de performance, les normes de performance, les exigences sur la qualification de la fiabilité, les interfaces matérielles et logicielles et les méthodes d’essais associées. Puisqu’un module dynamique intègre un module ou un dispositif optique, une carte imprimée et un logiciel ou un microprogramme, les normes développées dans la série calquent des normes existantes appropriées. D’autre part, un "module dynamique" étant une catégorie de produit relativement nouvelle, la série de normes sur les modules dynamiques n’est pas limitée par les pratiques existantes dans lesquelles les exigences diffèrent. Les normes de sécurité se rapportant aux modules dynamiques sont principalement des considérations sur la puissance optique, qui sont traitées par le Comité d’études 76 de l’IEC: Sécurité des rayonnements optiques et matériels laser. Cette deuxième édition annule et remplace la première édition parue en 2013. Cette éditions constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: l’inclusion des définitions du commutateur sélectif en longueur d’onde.
Dinamični moduli - Splošno in navodilo (IEC 62343:2017)
Standard IEC 62343 se uporablja za vse optične dinamične module in naprave, ki so na voljo na tržišču. Opisuje izdelke, ki jih zajema skupina standardov IEC 62343-X, določa terminologijo, glavne dejavnike in osnovne pristope.
Namen tega dokumenta je:
• vzpostaviti enotne zahteve za delovanje, zanesljivost in okoljske lastnosti dinamičnih modulov (DM), ki bodo vključene v ustrezne standarde modulov DM; in
• zagotoviti pomoč kupcu pri izbiri izdelkov DM z dosledno visoko kakovostjo za njegov način uporabe in ustreznih standardov za module DM.
Ta dokument zajema predloge delovanja, standarde delovanja, kvalifikacijske zahteve glede zanesljivosti, vmesnike strojne in programske opreme ter povezane preskusne metode.
Ker dinamični modul vključuje optični modul/napravo, tiskano vezje ter programsko/strojno opremo, bodo standardi, razviti v tej seriji, posnemali ustrezne obstoječe standarde. Ker pa je »dinamični modul« relativno nova kategorija izdelka, obstoječe prakse ne bodo zavezujoče za skupine standardov za dinamični modul, kjer se zahteve razlikujejo.
Varnostni standardi, povezani z dinamičnimi moduli, obravnavajo zlasti optično moč, kar zajema standard IEC TC 76: Varnost pri optičnem sevanju in laserska oprema.

DYNAMIC MODULES – GENERAL AND GUIDANCE
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 has been prepared by subcommittee 86C: Fibre optic
systems and active devices, of IEC technical committee 86: Fibre optics.
This second edition cancels and replaces the first edition published in 2013. This edition
constitutes a technical revision.
This edition includes the following significant technical change with respect to the previous
edition: the inclusion of definitions for the wavelength selective switch.
The text of this International Standard is based on the following documents:

INTRODUCTION
IEC 62343 applies to dynamic devices as defined in IEC TS 62538. This document contains
general guidance for the IEC 62343 series related to dynamic devices and definitions which
apply to dynamic devices. The dynamic module (DM), or device, has two distinguishing
characteristics: dynamic and module.
"Dynamic" highlights the functions of the products to include "tuning, varying, switching,
configuring, and other continuous optimization," often accomplished by electronics, firmware,
software or their combinations. The dynamic device usually has a certain level of intelligence
to monitor or measure the situation and make decisions for necessary (optimization) actions.
The behaviour of dynamic modules may be characterized by transient characteristics as the
dynamic module undergoes tuning, switching, configuring and other continuous optimization.
Characterization of transient characteristics will be considered in individual dynamic module
standards.
"Module" defines that the products covered by the standard are the integration of active and
passive components (either or both), through interconnecting materials or devices. The
controlling electronics can be inside or outside the optical package (that contains all or most
of the optical components and interconnection). The product can look like a small printed
wiring board (PWB or child-board with mounted optical module) or a small box (housing) with
optical components and electronics enclosed. In the former case, it is more like an assembly
(generally not packaged in a box or housing) than a module (generally packaged in a box or
housing).
For historical reasons and convenience, a dynamic module or device is referred to as a
dynamic module in the IEC 62343 series.
The number of dynamic modules and devices is rapidly growing as optical communications
networks evolve. The following list provides some examples of the products covered by the
IEC 62343 series. It should be noted that the list is not exhaustive and the products to be
covered are not limited by the listed examples:
• channel gain equalizer;
• dynamic channel equalizer;
• dynamic gain tilt equalizer;
• dynamic slope equalizer;
• tuneable chromatic dispersion compensator;
• polarization mode dispersion compensator;
• reconfigurable optical add-drop multiplexer;
• switch with monitoring and controls;
• variable optical attenuator with monitoring and controls;
• optical channel monitor;
• wavelength selective switch;
• multicast optical switch.
The IEC 62343 series will cover performance templates, performance standards, reliability
qualification requirements, hardware and software interfaces, and related testing methods.
The structure of the IEC 62343 series, under the general title Dynamic modules, is as follows:
• 62343-1 series Part 1: Performance standards
• 62343-2 series Part 2: Reliability qualification
---------------------- Page: 11 ----------------------
SIST EN 62343:2018
– 6 – IEC 62343:2017 © IEC 2017
• 62343-3 series Part 3: Performance specification templates
• 62343-4 series Part 4: Software and hardware interface standards
• 62343-5 series Part 5: Test methods
• 62343-6 series Part 6: Design guides
A complete set of standards related to a dynamic module or device should include the
following:
• optical performance standards;
• reliability qualification standards;
• optical performance specification templates;
• hardware and software interface standards;
• test methods;
• technical reports.
The safety standards related to dynamic modules are mostly optical power considerations,
which are covered by IEC TC 76: Optical radiation safety and laser equipment.
Only those dynamic modules for which standards are complete or in preparation are included
in Clause 3. To reflect the rapidly growing market for dynamic modules, additional terms and
definitions will be added in subsequent revisions as the series expands.
It should be noted that optical amplifiers could be regarded as dynamic modules. They are not
included in the IEC 62343 series but are covered in their own series of IEC standards.
