Single-mode fibre optic connector performance for harsh industrial
operating conditions

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.
A PAS is a technical specification not fulfilling the requirements for a standard, but made
available to the public.
IEC-PAS 61753-1-3 has been processed by subcommittee 86B: Fibre optic interconnecting
devices and passive components, of IEC technical committee 86: Fibre optics.
The text of this PAS is based on the This PAS was approved for

Following publication of this PAS, which is a pre-standard publication, the technical committee
or subcommittee concerned may transform it into an International Standard.
This PAS shall remain valid for an initial maximum period of 3 years starting from the
publication date. The validity may be extended for a single 3-year period, following which it
shall be revised to become another type of normative document, or shall be withdrawn.

3 Terms and definitions
For the purpose of this document, the following terms and definitions apply.
3.1
change in attenuation
peak-to-peak variation (see Table A-12, IEC 61753-1)
3.2
sample
a complete set of passive connector components consisting of a free plug and a socket. The
socket may be mounted in an enclosure. This allow demountable coupling between pairs of
optical fibres
3.3
patch cord assembly
two connector plugs mated consisting of a free plug and a socket with each socket
mechanically mounted in an enclosure. Each of the non terminated leads from the socket
should be at least 3 m long so that the splices may be located outside of the environmental
test chamber (see also Figure 1)
4 Industrial environment
4.1 General
Fibre optic components are frequently used in industrial environments, like control stations,
power rooms or inside switch cabinets. The special environmental conditions such as
temperature, dust, moisture, vibration, chemicals, etc. in industrial deployment require more
rugged components than found in standard environments.
4.2 Cross-reference with MICE
The MICE methodology from ISO/IEC/TR 29106 classifies the environment local to a cabling
system in terms of mechanical, ingress, climatic and chemical and electromagnetic
characteristics. The tests and severities in Clause 9 of this PAS are intended to reflect the M
3
and I environment. The climatic conditions and chemical substances used are selected from
3
the C environment. The defined tests and severities are according to IEC 60068-2-60
3
NOTE  Not all chemical substances are used.

5 Tests
5.1 General
The defined performance test procedures should:
– evaluate the product for two basic acceptance criteria: mechanical integrity and optical
transmission requirements;
– simulate the effects of exposure to the environment in which it will be installed;
– simulate installation and intervention conditions;
– evaluate all specified features of the product.
The defined performance test procedures should simulate the situation in a mated condition
under use in a harsh industrial environment. It is not the intention to simulate the situation:
– when being mated or demated;
– during the assembling of the connector;
– during transportation and storage of the connector.
All test methods are in accordance with IEC 61300 series as defined in Table 3.
Each test defines the number of samples to be evaluated as described in Annex A. The
samples used for each test should be composed of randomly selected and previously
unstressed new samples but may also be selected from previously used samples if desired.
The connectors under test shall be terminated onto single-mode fibre per IEC 60793-2-50,
type B1.1 or B1.3. The connector interface standard shall meet the dimensions of IEC 61754
series and the connector optical interface standard shall meet the relevant requirements of
IEC 61755 series.
Unless otherwise specified, tests should be carried out under standard atmospheric conditions
according to IEC 61300-1. The optical criteria for each test shall be as defined in Clause 9,
(see also notes to Table 1).
5.2 Sample size
As a minimum requirement and if not otherwise mentioned, the tests can be run individually
on five samples per test only. It is intended that new samples should be used for each test
however samples may be reused at the manufacturer’s own risk. In the event that this reuse
causes a failure, the test may be rerun with new samples.
Samples for the attenuation test are to be randomly selected and randomly mated as new
product, starting with 10 DUT, see Figure 1 (e.g. as duplex version, see also Annex A).
6 Test report
Fully documented test reports and supporting evidence shall be prepared and available for
inspection to show that the tests have been carried out and the results are satisfactory; the
requested performances (see Table 1 for the grades) should be defined before starting the
tests.
7 Reference component
No reference components are required to perform the tests in this standard.

8 Performance requirements
8.1 General
The protection level of the connector according to IEC 60529 shall be defined before
performing the tests. The minimum protection level shall be IP x5 and IP x7 for immersion and
IP 6x for dust, so the resulting level will be IP65 and IP67.
8.2 Dimensions
Dimensions shall comply with the appropriate IEC interface standard as defined in IEC 61754
series.
8.3 Sample definition and size
Default sample sizes for the tests are defined in 5.1.
Reliability tests for life time expectations are not covered by this standard.
For the purposes of this standard, a sample (DUT) is a mated connector set. Products under
test shall be mounted and cleaned according to the manufacturer’s instructions.
Where the connector arrangement is a plug and a bulkhead flange, Figure 1 shows a
proposed sample.
