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 62343-2-1 has been prepared by subcommittee 86C: Fibre optic
systems and active devices, of IEC technical committee 86: Fibre optics.
This first edition cancels and replaces the second edition of IEC 62343-2 published in 2014.
This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to
IEC 62343-2:2014:
a) addition of an Introduction to the background of this document;
b) replacement of "Reliability qualification consideration" by "reliability qualification test
consideration";
c) deletion of the consideration of "Design 1" and "Design 2" and change of the contents of
"Approach" in "Reliability qualification test considerations";
d) deletion of the details in "Reliability qualification requirements" and replacement by
"Reliability qualification test items";

e) deletion of "Reliability calculations" from the sum of failure rates of constituting parts;
f) Integration of "Pass/fail criteria" and "Guidance of FMEA" into Annex B (informative);
g) Simplification of test items and conditions in Annex A and change of title of Annex A to
"Examples of reliability qualification test conditions".
The text of this International Standard is based on the following documents:
CDV Report on voting
86C/1567/CDV 86C/1594/RVC

INTRODUCTION
Dynamic modules (DMs) are relatively new fibre optic devices. In the industry, there is no de-
facto standard of reliability qualification test requirements for DMs. Also, there are many types
and functions of DMs, such as optical path switching, wavelength management, chromatic
dispersion management, optical channel power management, and optical channel powers and
wavelength monitoring. Therefore, it is difficult to standardize the reliability qualif
