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 61753-051-02 has been prepared by subcommittee 86B: Fibre optic interconnecting
devices and passive components, of IEC technical committee 86: Fibre optics. It is an
International Standard.
This first edition cancels and replaces IEC 61753-051-3 published in 2013. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to
IEC 61753-051-3:2013:
a) change the category from U to C and the test items and their conditions according to
IEC 61753-1;
b) change the requirements reflecting the survey results.

INTRODUCTION
The performance standard of single-mode plug style optical attenuators has been published in
1
2001 as IEC 61753-051-3 [1] . After publication of the corrigendum in 2004, the second edition,
in which test details and requirements were reconsidered, has been published in 2013. In 2019,
the market survey of five Japanese suppliers, two Chinese ones and one Swiss has been carried
out. As a result of the survey, it was revealed that some suppliers could not comply to the
category U requirements. It was decided to withdraw IEC 61753-051-3 and establish this
document for category C reflecting the survey result.

31 FOREWORD
32 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
33 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
34 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
35 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
36 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
37 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
38 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
39 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
40 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
41 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
42 consensus of opinion on the relevant subjects since each technical committee has representation from all
43 interested IEC National Committees.
44 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
45 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
46 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
47 misinterpretation by any end user.
48 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
49 transparently to the maximum extent possible in their national and regional publications. Any divergence between
50 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
51 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
52 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
53 services carried out by independent certification bodies.
54 6) All users should ensure that they have the latest edition of this publication.
55 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
56 members of its technical committees and IEC National Committees for any personal injury, property damage or
57 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
58 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.
59 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
60 indispensable for the correct application of this publication.
61 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
62 rights. IEC shall not be held responsible for identifying any or all such patent rights.
63 International Standard IEC 61753-051-02 has been prepared by subcommittee SC86B: Fibre
64 optic interconnecting devices and passive components, of IEC technical committee TC86: Fibre

79 INTRODUCTION
80 The performance standard of single-mode plug style optical attenuators has been published in
81 2001 as IEC 61753-051-3, Ed.1, Fibre optic interconnecting devices and passive components
82 - Performance standard - Part 051-3: Single-mode fibre, plug style fixed attenuators for category
83 U - Uncontrolled environment. After publication of the corrigendum in 2004, the second edition
84 which test details and requirements were reconsidered has been published in 2013. In 2019,
85 the market survey of five Japanese suppliers, two Chinese ones and one Switzerland ones has
86 been carried out. As a result of the survey, it was revealed that some suppliers could not comply
87 the category U requirements. SC86B decided to withdraw IEC 61753-051-3 and establish this
88 document of IEC 61753-051-02 for category C reflecting the survey result.
