40 FOREWORD
41 1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
42 all national electrotechnical committees (IEC National Committees). The object of the IEC is to promote
43 international co-operation on all questions concerning standardization in the electrical and electronic fields. To
44 this end and in addition to other activities, the IEC publishes International Standards. Their preparation is
45 entrusted to technical committees; any IEC National Committee interested in the subject dealt with may
46 participate in this preparatory work. International, governmental and non-governmental organizations liaising with
47 the IEC also participate in this preparation. The IEC collaborates closely with the International Organization for
48 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
49 2) The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, an
50 international consensus of opinion on the relevant subjects since each technical committee has representation
51 from all interested National Committees.
52 3) The documents produced have the form of recommendations for international use and are published in the form
53 of standards, technical specifications, technical reports or guides and they are accepted by the National
54 Committees in that sense.
55 4) In order to promote international unification, IEC National Committees undertake to apply IEC International
56 Standards transparently to the maximum extent possible in their national and regional standards. Any divergence
57 between the IEC Standard and the corresponding national or regional standard shall be clearly indicated in the
58 latter.
59 5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
60 equipment declared to be in conformity with one of its standards.
61 6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
62 of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
63 International Standard IEC 60793-1-46 has been prepared by subcommittee 86A: Fibres and
64 cables, of IEC technical committee 86: Fibre optics.
65 This second edition cancels and replaces the first edition published in 2001 . This revision
66 constitutes a technical revision.
67 This edition includes the following significant technical changes with respect to the previous
68 edition:
69 a) inclusion of class C single mode intraconnection fibre;
70 b) replacement of ‘optical transmittance’ by ‘attenuation’;
71 The text of this standard is based on the following documents:
FDIS Report on voting

73 Full information on the voting for the approval of this standard can be found in the report on
74 voting indicated in the above table.
75 This publication has been drafted in accordance with the ISO/IEC Directives, Part 3.
76 Annexes A and B form an integral part of this standard.

103 – IEC 60793- 1-20 to IEC 60793-1-29: Measurement methods and test procedures for
104 dimensions
105 – IEC 60793- 1-30 to IEC 60793-1-39: Measurement methods and test procedures for
106 mechanical characteristics
107 – IEC 60793- 1-40 to IEC 60793-1-49: Measurement methods and test procedures for
108 transmission and optical characteristics
109 – IEC 60793-1-50 to IEC 60793-1-59: Measurement methods and test procedures for
110 environmental characteristics.

115 OPTICAL FIBRES –
117 Part 1-46: Measurement methods and test procedures –
118 Monitoring of changes in attenuation
122 1 Scope
123 This part of IEC 60793 establishes uniform requirements for the monitoring of changes in
124 attenuation, thereby assisting in the inspection of fibres and cables for commercial purposes.
125 This standard gives two methods for monitoring the changes in attenuation of optical fibres and
126 cables that occur during mechanical or environmental testing, or both. It provides a monitor in
127 the change of attenuation characteristics arising from optical discontinuity, physical defects and
128 modifications of the attenuation slope:
129 – method A: change in attenuation by transmitted power;
130 – method B: change in attenuation by backscattering.
131 Methods A and B apply to the monitoring of all categories of the following fibres:
132 – class A: multimode fibres;
133 – class B: single-mode fibres;
134 – class C: single-mode intraconnection fibres.
136 Information common to both measurements is contained in clauses 1 to 10, and information
137 pertaining to each individual method appears in annexes A, and B respectively.
138 2 Normative references
139 The following normative documents contain provisions which, through reference in this text,
140 constitute provisions of this International Standard. For dated references, subsequent
141 amendments to, or revisions of, any of these publications do not apply. However, parties to
142 agreements based on this International Standard are encouraged to investigate the possibility
143 of applying the most recent editions of the normative documents indicated below. For undated
144 references, the latest edition of the normative document referred to applies. Members of IEC
145 and ISO maintain registers of currently valid International Standards.
