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 62343-1-3 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 2006. It constitutes a
technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) a change in the title removing the environmental category;
b) the addition of Clause 4, Operating and storage conditions;
c) the inclusion of spectral bands in Clause 5, Test;
d) a definition of the wavelength range for test requirements in Clause 5, Test;
e) the removal of the environment tests from the test details and requirements.

1 Scope
This part of IEC 62343 contains the guideline minimum initialization test and measurement
requirements and severities, for a dynamic gain tilt equalizer (DGTE).
A DGTE is used in an optical amplifier, which operates in C-band and/or L-band, to control the
output power of the amplifier to be nominally flat. The operating wavelength range of a DGTE
is wider than or equal to 35 nm.

5 Test
The characterization of a dynamic gain tilt equalizer requires demonstration that those
components or features within the module, together with that of the module itself, are capable
of yielding the performance requirements as defined in the relevant specification.
Where it can be adequately demonstrated that components or features have previously met
all of the requirements of a specific performance standard category, they may be declared as
complying with that performance standard. This may obviate the need for repeat testing of
components or features in such cases. Where this occurs, reference shall be made to the
relevant test reports or documentations.
All tests are to be carried out to validate performance over the required operating wavelength
range (wider than or equal to 35 nm). As a result, single or multiple spectral bands may be
chosen for the qualification and differing target specifications may be assigned to each
spectral band (C-band or L-band).
6 Test report
Fully documented test reports and supporting evidence shall be prepared and be available for
inspections as evidence that the tests have been carried out and complied with.
7 Performance requirements
7.1 Dimensions
Dimensions shall comply either with an appropriate IEC interface standard or with those given
in the manufacturer's drawings, where the IEC interface standard does not exist or cannot be
used.
7.2 Sample size
Three (3) DGTE modules are used in each test. The tests may be performed individually or in
sequential order.
The test sample size and sequencing requirements for the module components shall be
defined in the relevant specification.
7.3 Test details and requirements
The requirements are given only for non-connectorized DGTE devices. For connectorized
modules, the connector performances shall be in compliance with IEC 61753-021-2 and
IEC 61753-022-2.
The channel spacings, unless otherwise specified, shall be in accordance with ITU-T
Recommendation G.692.

The test details and requirements for performance standard are shown in Table 3.
For sequential testing, the data shall be analysed to determine the pass or failure for each
test.

indicative of values that must be met in an operational environment.
