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.
This redline version of the official IEC Standard allows the user to identify the changes
made to the previous edition IEC 60794-2-22:2016. A vertical bar appears in the margin
wherever a change has been made. Additions are in green text, deletions are in
strikethrough red text.

5.5 Ripcord
If required, a ripcord may be provided beneath the cable sheath. The functionality of the ripcord
shall be tested according to IEC 60794-1-21, method E25.
5.6 Cable sheath
The cable shall have an overall protective sheath. The cable diameter shall be specified in the
relevant detail specification (or product specification) agreed between customer and supplier.
5.7 Sheath marking
If required, the cable shall be marked as agreed upon between the customer and the supplier.
5.8 Examples of cable constructions
Examples of some main types of typical cable constructions are shown in Annex B. Other
configurations (e.g. multi-layer constructions) are not precluded if they meet the mechanical,
environmental and transmission requirements given in this document.
6 Tests
6.1 General
Compliance with the specification requirements shall be verified by carrying out tests selected
from Clause 6. It is not intended that all tests be carried out in all cases. The tests to be applied
and the frequency of testing shall need to be agreed upon between the customer and the
supplier.
As a general requirement for the tests specified in this document, the spirit is to keep "no change
in attenuation" criteria at the end of each evaluation, although the parameters specified in this
document may be affected by measurement uncertainty arising either from measurement errors
or calibration errors. The optical total uncertainty of measurement for this document shall be
±0,05 dB for single-mode fibres and ±0,2 dB for multimode fibres. Any measured value within
this range shall be considered as "no change in attenuation".
Single-mode cables shall be measured at 1 550 nm and multimode cables at 1 300 nm.
Measurement at other wavelengths may be agreed between the customer and the supplier.
Measurements of attenuation shall be carried out according to IEC 60793-1-40. Change in
attenuation measurements shall be carried out according to IEC 60793-1-46. The maximum
change in attenuation refers to the ± deviation from the original value at ambient temperature
before the test.
NOTE The optimized wavelength for multimode fibres A1-OM3 and A1-OM4 is 850 nm and for A1-OM5 fibre, the
targeted operational wavelength range is in the vicinity of 850 nm to 950 nm.
If cable loops are used within a test to fix the ends of a cable, the loop diameter shall be equal
or greater than the specified minimum cable bend diameter to avoid cable damage and
excessive mode filtering in multimode fibre.
Unless otherwise specified, all tests shall be carried out at ambient temperature, as described
in IEC 60793-1-1 expanded test conditions as specified in IEC 60794-1-2.
The following tests can be performed on a short sample length of cable which is still a part of a
longer length. Thus, it becomes possible to detect permanent changes in attenuation. The
measuring wavelength and maximum value of the attenuation change for longer lengths shall
be agreed upon between the customer and the supplier.

6.2 Dimensions
The fibre dimensions and tolerances shall be verified in accordance with IEC 60793-1-20 or
IEC 60793-1-21. The diameter of the buffer, simplex optical fibre cable and of the cable, as well
as the thickness of the sheath, shall be measured in accordance with the methods of
IEC 60811-202 and IEC 60811-203.
6.3 Mechanical requirements
6.3.1 General
The cable shall fulfil the mechanical requirements of tensile, crush, impact and repeated
bending according to IEC 60794-2-20. The exceptions to IEC 60794-2-20 are defined in the
following clauses. The specific requirements for this cable type are defined in 6.3.

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.
IEC 60794-2-22 has been prepared by subcommittee 86A: Fibres and cables, of IEC technical
committee 86: Fibre optics. It is an International Standard.
This second edition cancels and replaces the first edition published in 2016. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) changed partly the wording in the title and the scope to align with IEC 60794-2-50,
IEC 60794-2-23 and IEC 60794-2-24;
b) added IEC 60793-1-40, IEC 60793-1-46 and IEC 60794-1-2 to the normative references;
c) deleted reference to IEC 60794-2-51;
d) added the definition of terminated breakout cable assembly;

e) changed the number of bend cycles from 10 to 3 to harmonise with IEC 60794-2-50;
f) changed test parameters for temperature cycling to harmonise with IEC 60794-2-50;
g) added maximum attenuation requirements after temperature cycling;
h) replaced the text for the fire performance with an improved description.
The text of this International Standard is based on the following documents:
