39 FOREWORD
40 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
41 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
42 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
43 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
44 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
45 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
46 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
47 with the IEC also participate in this preparation. 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 IEC on technical matters express, as nearly as possible, an international
50 consensus of opinion on the relevant subjects since each technical committee has representation from all
51 interested IEC National Committees.
52 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
53 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
54 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
55 misinterpretation by any end user.
56 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
57 transparently to the maximum extent possible in their national and regional publications. Any divergence between
58 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
59 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
60 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
61 services carried out by independent certification bodies.
62 6) All users should ensure that they have the latest edition of this publication.
63 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
64 members of its technical committees and IEC National Committees for any personal injury, property damage or
65 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
66 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.
67 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
68 indispensable for the correct application of this publication.
69 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
70 rights. IEC shall not be held responsible for identifying any or all such patent rights.
71 International Standard IEC 61753-042-02 has been prepared by subcommittee 86B: Fibre optic
72 interconnecting devices and passive components of IEC technical committee 86: Fibre optics.
73 This first edition cancels and replaces the first edition of IEC 61753-042-2, published in 2014,
74 and constitutes a technical revision.
75 This edition includes the following significant technical changes with respect to IEC 61753-042-
76 2.:
78 a) Harmonization of test requirements with requirements from IEC 61753-1:2018
79 b) Harmonization of tests with tests from IEC 61753-1:2018
80 The text of this standard is based on the following documents:
