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:
FDIS Report on voting
86C/1444/FDIS 86C/1450/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.

A list of all the parts in the IEC 62343 series, published under the general title Dynamic
modules, can be found on the IEC website.
The committee has decided that the contents of this publication will remain unchanged until
the stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data
related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,

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.
