OPTICAL FIBRE CABLES –
Part 2-10: Indoor optical fibre cables –
Family specification for simplex and duplex cables
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 60794-2-10 has been prepared by subcommittee 86A: Fibres and cables, of IEC technical

committee 86: Fibre optics. It is an International Standard.

This third edition cancels and replaces the second edition published in 2011. This edition

constitutes a technical revision.

This edition includes the following significant technical changes with respect to the previous

edition:
a) updating of normative references;

b) updating of all relevant A1 and B1 fibre category and sub-category designations.

This International Standard is to be used in conjunction with IEC 60794‑1‑1:2022,

IEC 60794‑1‑2:2021, IEC 60794‑1‑21:2015 and IEC 60794‑1‑21:2015/AMD1:2020,

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 the values agreed between the customer and the supplier. The materials in

the cable shall not present a health or environmental hazard within its intended use.

There shall be no fibre splice in a delivery length unless otherwise agreed between the customer

and the supplier.

It shall be possible to identify each individual fibre throughout the length of the cable.

4.2 Optical fibres and primary coating

Multimode or single-mode optical fibres shall be used which meet the requirements of

IEC 60793-2.
4.3 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 minimum length of 15 mm, depending on customer requirements. For

semi-tight buffers, the buffer shall be easily removable over a minimum length of 300 mm. For

loose buffers, the buffer shall be easily removable over a length of not less than 1,0 m.

85 FOREWORD

86 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

87 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international

88 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and

89 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,

90 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their

91 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with

92 may participate in this preparatory work. International, governmental and non-governmental organizations liaising

93 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for

94 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.

95 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

96 consensus of opinion on the relevant subjects since each technical committee has representation from all

97 interested IEC National Committees.

98 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

99 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

100 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

101 misinterpretation by any end user.

102 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

103 transparently to the maximum extent possible in their national and regional publications. Any divergence between

104 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.

105 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

106 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

107 services carried out by independent certification bodies.

108 6) All users should ensure that they have the latest edition of this publication.

109 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

110 members of its technical committees and IEC National Committees for any personal injury, property damage or

111 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

112 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

113 Publications.

114 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

115 indispensable for the correct application of this publication.

116 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent

117 rights. IEC shall not be held responsible for identifying any or all such patent rights.

118 International Standard IEC 60794-2-10 has been prepared by sub-committee 86A: Fibres and

119 cables, of IEC technical committee 86: Fibre optics.

120 This third edition cancels and replaces the second edition published in 2011. It constitutes a

121 technical revision.
122 The main changes with respect to the previous edition are as follows:
123 – Updating of normative references

124 – Updating of all relevant A1 and B1 fibre category and sub-category designations

125 This standard is to be used in conjunction with IEC 60794-1-1, IEC 60794-1-2, IEC 60794-1-

126 21, IEC 60794-1-22, IEC 60794-1-23 and IEC 60794-2.
