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 61753-081-2 has been prepared by subcommittee 86B: Fibre optic
interconnecting devices and passive components, of IEC technical committee 86: Fibre optics.
This second edition cancels and replaces the first edition published in 2009 and constitutes a
technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
– to add passband ripple as a test item;
– to revise details to be specified and the formats of Tables 2, 3 and 4;
– to add IEC 61300-3-38 as a normative reference.

PERFORMANCE STANDARD –
Part 081-2: Non-connectorized single-mode fibre optic middle-scale
1 × N DWDM devices for category C – Controlled environments

1 Scope
This part of IEC 61753 contains the minimum initial test and measurement requirements and
severities which a fibre optic middle-scale 1 × N (16 ≤N ≤64) DWDM (dense wavelength
division multiplexing) device with channel spacing of 50 GHz, 100 GHz or 200 GHz needs to
satisfy in order to be categorized as meeting the requirements of category C – Controlled
environment. The requirements are given for the DWDM devices with Gaussian passband
profile and flat-top passband profile. The requirements cover devices with single-mode non-
connectorized pigtails and no circuit board.

4 Test conditions – General
Unless otherwise specified, all test methods shall be in accordance with the IEC 61300 series.
The samples shall be terminated onto single-mode fibres as per IEC 60793-2-50:2012
category B1.1 or B1.3 or B6 in either coated fibres (primary and secondary) or reinforced
cable format as per IEC 60794-2-50. DWDM devices used for each test are intended to be
previously unstressed new samples but may also be selected from previously used samples, if
desired. All measurements shall be carried out at normal room temperature, unless otherwise
stated. If the device is provided with an active temperature control, this shall be set at the set-
point specified by the manufacturer.
The requirements apply to every combination of input and output port.
All tests shall be carried out to validate performance over the required operating wavelength
range. 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.
The following Table 1 is intended to provide guidance on the wavelength ranges of the
various spectral bands. It is not intended for specification. Values of operating wavelength
used in performance verification shall be defined in the manufacturer’s specification.

AVANT-PROPOS
1) La Commission Electrotechnique Internationale (l'IEC) est une organisation mondiale de normalisation
composée de l'ensemble des comités électrotechniques nationaux (Comités nationaux de l'IEC). L'IEC a pour
objet de favoriser la coopération internationale pour toutes les questions de normalisation dans les domaines
de l'électricité et de l'électronique. A cet effet, l'IEC – entre autres activités – publie des Normes internationales,
des Spécifications techniques, des Rapports techniques, des Spécifications accessibles au public (PAS) et des
Guides (ci-après dénommés "Publication(s) de l'IEC"). Leur élaboration est confiée à des comités d'études, aux
travaux desquels tout Comité national intéressé par le sujet traité peut participer. Les organisations
internationales, gouvernementales et non gouvernementales, en liaison avec l'IEC, participent également aux
travaux. L'IEC collabore étroitement avec l'Organisation Internationale de Normalisation (ISO), selon des
conditions fixées par accord entre les deux organisations.
2) Les décisions ou accords officiels de l'IEC concernant les questions techniques représentent, dans la mesure
du possible, un accord international sur les sujets étudiés, étant donné que les Comités nationaux de l'IEC
intéressés sont représentés dans chaque comité d’études.
3) Les Publications de l'IEC se présentent sous la forme de recommandations internationales et sont agréées
comme telles par les Comités nationaux de l'IEC. Tous les efforts raisonnables sont entrepris afin que la IEC
s'assure de l'exactitude du contenu technique de ses publications; l'IEC ne peut pas être tenue responsable de
l'éventuelle mauvaise utilisation ou interprétation qui en est faite par un quelconque utilisateur final.
4) Dans le but d'encourager l'uniformité internationale, les Comités nationaux de l'IEC s'engagent, dans toute la
mesure possible, à appliquer de façon transparente les P
