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) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
shall not be held responsible for identifying any or all such patent rights.
IEC 61753-081-02 has been prepared by subcommittee 86B: Fibre optic interconnecting
devices and passive components, of IEC technical committee 86: Fibre optics. It is an
International Standard.
This first edition cancels and replaces IEC 61753-081-2 published in 2014. This edition
constitutes a technical revision.

– 4 – IEC 61753-081-02:2023 © IEC 2023
This edition includes the following significant technical changes with respect to
IEC 61753-081-2:2014:
a) change of test conditions harmonizing with IEC 61753-1:2018;
b) harmonization of the measurement uncertainties in Table 2 to Table 4 with
IEC 61753-081-03 and IEC 61753-081-06.
The text of this International Standard is based on the following documents:

Full information on the voting for its approval can be found in the report on voting indicated in
the above table.
The language used for the development of this International Standard is English.
This document was drafted in accordance with ISO/IEC Directives, Part 2, and developed in

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) arrayed waveguide grating device with channel spacing of 50 GHz,
100 GHz or 200 GHz satisfies 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 exclude the devices
with dynamic electrical temperature control.

4 Test
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 category
B‑652.B, B-652.D or B-657 on either coated fibres (primary and secondary) or reinforced cable
format as per IEC 60794-2-50. DWDM devices used for the test are intended to be previously
unstressed new samples but may also be selected from previously used samples. All
measurements shall be carried out at the standard atmospheric condition defined in
IEC 61300‑1, unless otherwise stated. If the device is provided with 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.
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.
