Foreword
The text of document 86A/737/FDIS, future edition 1 of IEC 60793-2-40, prepared by SC 86A, Fibres
and cables, of IEC TC 86, Fibre optics, was submitted to the IEC-CENELEC parallel vote and was
approved by CENELEC as EN 60793-2-40 on 2002-03-05.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2002-12-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2005-03-01
Annexes designated "normative" are part of the body of the standard.
In this standard, annexes A, B, C, D and ZA are normative.
Annex ZA has been added by CENELEC.
Compared to IEC 60793-1:1989 and IEC 60793-2:1992, IEC/SC 86A has adopted a revised structure
of the new IEC 60793 series: The individual measurement methods and test procedures for optical
fibres are published as "Part 1-XX"; the product standards are published as "Part 2-XX".
The general relationship between the new series of EN 60793 and the superseded European
Standards of the EN 188000 series is as follows:

FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60793-2-40 has been prepared by subcommittee 86A: Fibres and
cables, of IEC technical committee 86: Fibre optics.
This part 2-40 constitutes part of the IEC 60793-2 series, fifth edition. This series has been
1
restructured and is composed of IEC 60793-2: Product specifications – General as well as
various parts IEC 60793-2-x, devoted to different types of fibres. The IEC 60793-2 series as a
whole replaces the fourth edition of IEC 60793-2, published in 1998, of which it constitutes a
technical revision
The text of this standard is based on the following documents:
FDIS Report on voting
86A/737/FDIS 86A/755/RVD
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 3.

Part 2-40: Product specifications –
Sectional specification for category A4 multimode fibres
1 Scope and object
This part of IEC 60793-2 is applicable to optical fibre types A4a, A4b, A4c, and A4d. These
fibres are used or can be incorporated in information transmission equipment and optical fibre
cables (typically up to 100 m).
Three types of requirements apply to these fibres:
• general requirements, as defined in IEC 60793-2;
• specific requirements common to the category A4 multimodal fibres covered in this
standard and which are given in clause 3;
• particular requirements applicable to individual fibre types or specific applications, which
are defined in the normative family specification annexes.
2 Normative references
