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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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 61753-082-2 has been prepared by subcommittee 86B: Fibre optic
interconnecting devices and passive components, of IEC technical committee 86: Fibre optics.
The text of this standard is based on the following documents:
FDIS Report on voting

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.

The committee has decided that the contents of this publication will remain unchanged until
the maintenance result 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

1 Scope
This part of IEC 61753 contains the minimum initial test and measurement requirements and
severities which a fibre optic 1,31/1,55 μm WWDM (wide wavelength division multiplexing)
device shall satisfy in order to be categorised as meeting the IEC standard, category C,
controlled environment. The requirements cover devices with single-mode pigtails.

3 Test procedure
Unless otherwise specified, all test methods are in accordance with IEC 61300 series
standard. Each test defines the number of samples to be evaluated. The samples used for
each test are intended to be previously unstressed new samples but may also be selected
from previously used samples if desired. The samples shall be terminated onto single-mode
fibres as per IEC 60793-2-50, Type B 1.1, in either coated fibres (primary and secondary) or
reinforced cable format. All measurements shall be carried out at normal room conditions,
unless otherwise stated.
All tests are to be carried out to validate performance over the required operating wavelength
range. All tests shall be carried out over the complete optical wavelength range.
The operating wavelength ranges are different for different variants of WWDM and may vary
depending on the application. The operating wavelength ranges for used WWDM are pointed
out in Table 1.
61753-082-2 © IEC:2008 – 7 –
Table 1 – Operating wavelength range
Operating wavelength Operating
range wavelength range
Variant 1 1290 nm – 1330 nm 1530 nm – 1570 nm
Variant 2 1270 nm – 1350 nm 1510 nm – 1590 nm

NOTE Other variants with different nominal channel central wavelengths and operating wavelength ranges can be
defined similarly in accordance with IEC/PAS 62074-1.
4 Test report
Fully documented test reports and supporting evidence shall be prepared and be available for
inspection as evidence that the tests have been carried out and complied with.
5 Reference components
The testing for these components does not require the use of reference components.
6 Performance requirements
6.1 Dimensions
Dimensions shall comply with either an appropriate IEC interface standard or with those given
in appropriate manufacturers drawings, where the IEC interface standard does not exist or
cannot be used.
6.2 Test details and requirements
The requirements are given only for pigtailed WDM devices. The connector performances
shall be in compliance with IEC 61753-021-2.
