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.

3 Construction
3.1 General
In addition to the constructional requirements in IEC 60794-2, the following apply to simplex
and duplex indoor cables.
The cable shall be designed and manufactured for an expected operating lifetime of at least
15 years. In this context, the attenuation of the installed cable at the operational
wavelength(s) shall not exceed values agreed between the customer and the supplier. The
materials in the cable shall not present a health hazard within its intended use.
There shall be no fibre splice in a delivery length unless otherwise agreed by the customer
and the supplier.
It shall be possible to identify each individual fibre throughout the length of the cable.
3.2 Optical fibres and primary coating
Multimode or single-mode optical fibres shall be used which meet the requirements of
IEC 60793-2.
3.3 Buffer
If a buffer is required, it shall consist of one or more layers of inert material. The buffer shall
be easily removable. For tight buffers, the buffer and fibre primary coating shall be removable
in one operation over a length of 10 mm to 25 mm, depending on customer requirements. For
semi-tight buffers, the buffer shall be easily removable over a length of 0,3 m to 0,5 m. For
loose buffers, the buffer shall be easily removable over a length of not less than 1,0 m.
Buffer dimensions are shown in Table 1.

Tight buffer 0,3 to 1,0
± 0,05
3.4 Ruggedised fibre
Further protection can be provided to buffered fibres by surrounding one or two of the fibres
with non-metallic strength members within a sheath of suitable material.
3.5 Slotted core
Cables of this construction are not commonly used.

– 8 – 60794-2-10  IEC:2011
3.6 Tube
One or two primary coated or buffered fibres are packaged (loosely or not) in a tube
construction which may be filled. The tube may be reinforced with a composite wall.
If required the suitability of the tube shall be determined by an evaluation of its kink
resistance in accordance with IEC 60794-1-2, Method G7.
3.7 Stranded loose tube
Cables of this construction are not commonly used.
3.8 Ribbon structure
Cables of this construction are not commonly used.
3.9 Strength and anti-buckling members
The cable shall be designed with sufficient strength members to meet installation and service
conditions so that the fibres are not subjected to strain in excess of limits agreed between the
customer and the supplier.
The strength and/or anti-buckling member may be either metallic or non-metallic and may be
located in the cable core and/or under the sheath and/or in the sheath.
3.10 Ripcord
Ripcords are not commonly used.
3.11 Sheath
The cable shall have an overall protective sheath. The cable diameter shall be specified in the
relevant detail specification (or product specification).
3.12 Sheath marking
If required, the cable shall be marked according to the local regulations or the agreement
between the customer and the supplier.
3.13 Identification
In case of duplex cables, the cable design should enable clear polarity identification for each
individual fibre. When fibre colouring is used for identification, standard colours shall be used
as closely as possible (reasonable match) to IEC 60304.
3.14 Examples of cable constructions
Examples of some main types of cable construction are shown in Annex A. Other
configurations are not excluded if they meet the mechanical, environmental and transmission
requirements given in this specification.
4 Dimensions – Optical fibres and primary coating
The dimensions of the individual primary coated fibres in the finished product shall be in
accordance with one of the sectional specifications defined in IEC 60793-2. The fibre
dimensions (e.g. cladding diameter or outer diameter including colouring) shall be verified in
accordance with IEC 60793-1-20 or IEC 60793-1-21.

60794-2-10  IEC:2011 – 9 –
5 Tests
5.1 General
Compliance with specification requirements shall be verified by carrying out tests selected
from the following subclauses. It is not intended that all tests shall be carried out; the
frequency of testing shall be agreed between customer and supplier.
Unless otherwise specified, all tests shall be carried out at ambient temperature.
5.2 Dimensions
The fibre dimensions and tolerances shall be checked in accordance with test method
IEC 60793-1-20 or IEC 60793-1-21. The diameter of the buffer and of the cable, as well as
the thickness of the sheath, shall be measured in accordance with the methods of
IEC 60811-1-1.
5.3 Mechanical requirements
Some of the following tests can be performed on a short sample length of cable which is still
an integral part of a longer length. Thus it becomes possible to detect permanent changes in
attenuation. The maximum value of this attenuation change shall be agreed between
customer and supplier.
5.3.1 Tensile performance

strength members of each simplex cable, e.g. Figures A.5, A.6 (without optional strength member) and A.7, the
tensile requirement for the duplex cable shall be double that for the simplex cable. The rationale is that those
simplex cables may be taken out from the duplex cable and will be independently used.
NOTE 2 Requirements of tensile load depends on construction of cables. Lower values may be adopted for some
types of cables e.g. small factor simplex cables.

B.2 Additional requirements for cables subject to the MICE environmental
classification (ISO/IEC 24702 and related standards)
Cables intended for installation in conformity with ISO/IEC 24702 and related standards may
require the specification of additional tests to ensure their suitability in the applicable
environments defined by the Mechanical, Ingress, Climatic and Chemical, and
Electromechanical (MICE) classification. Such tests are outside of the scope of IEC 60794
cable specifications, and MICE criteria are not part of the requirements for 60794
specifications. The MICE tests may be the same as, similar to, or substantially different from,
the tests required by IEC 60794 specifications. Cables manufactured per IEC 60794
specifications may or may not meet the MICE criteria. For supplemental discussion see
TR62362.
