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 61753-022-2 has been prepared by sub-committee 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 2003. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
– reconsideration of test requirements and details.

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.
A list of all the parts in the IEC 61753 series, published under the general title, Fibre optic
interconnecting and passive components – Perfomance standard can be found on the IEC

Future standards in this series will carry the new general title as cited above. Titles of existing
standards in this series will be updated at the time of the next edition.
The committee has decided that the contents of this publication will remain unchanged until
the stability 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

3 Test
All test methods are in accordance with the IEC 61300 series.
The connector shall be terminated onto multimode fibre as per IEC 60793-2-10, fibre type A1a
or A1b, in either secondary coated or reinforced cable format.
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 be selected from previously used samples if so desired.
All optical testing shall be carried out at one central wavelength only, this shall be either
850 nm ± 30 nm.
Source characteristics shall be S2, S3 and detector D1, as specified in IEC 61300-3-4.
Launch conditions shall be in accordance with IEC 61300-1.
The full set of tests shall be carried out for all fibre types for which compliance to this
standard is claimed.
For different cable structures only requalification to tests 4, 6, 9, 10, 11, 12, 13 and 14 is
requested.
Change in attenuation, for the purpose of the test, is defined as the peak-to-peak variation
and shall be measured using IEC 61300-3-3. For monitoring intermittent discontinuities during
a test, IEC 61300-3-28 shall be used.

61753-022-2 © IEC:2012 – 7 –
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 Performance requirements
5.1 Dimensions
Dimensions shall comply with the appropriate IEC interface standard.
5.2 Sample size
For the purposes of this standard, a sample is a connector set, defined as the complete set of
connector components required to provide demountable coupling between one or more pairs
of optical fibres, i.e. “cable-plug-adapter-plug-cable” or “cable-socket-plug-cable”. The length
of cable (or fibre) inside the chamber on each side of the connector set should be 1,5 m
minimum.
The sample sizes to be used for the tests shall be as defined in Annex A. Samples may either
be a new product or sourced from a previous test.
5.3 Test details and requirements
Table 1 gives test details and requirements.
