45 FOREWORD
46 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
47 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
48 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
49 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
50 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
51 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
52 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
53 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
54 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
55 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
56 consensus of opinion on the relevant subjects since each technical committee has representation from all
57 interested IEC National Committees.
58 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
59 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
60 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
61 misinterpretation by any end user.
62 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
63 transparently to the maximum extent possible in their national and regional publications. Any divergence between
64 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
65 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
66 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
67 services carried out by independent certification bodies.
68 6) All users should ensure that they have the latest edition of this publication.
69 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
70 members of its technical committees and IEC National Committees for any personal injury, property damage or
71 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
72 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
73 Publications.
74 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
75 indispensable for the correct application of this publication.
76 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
77 rights. IEC shall not be held responsible for identifying any or all such patent rights.
78 IEC 61753-021-03 has been prepared by subcommittee 86B: Fibre optic interconnecting
79 devices and passive components, of IEC technical committee 86: Fibre optics. It is an
80 International Standard.
81 This first edition cancels and replaces the first edition of IEC 61753-021-3 published in 2012.
82 This edition constitutes a technical revision.
83 This edition includes the following significant technical changes with respect to
84 IEC 61753-021-3:2012:
85 a) updated environmental category (from U to OP), tests and their severities according to
86 IEC 61753-1;
87 b) changed the term and definitions of the different type of test samples (pigtail test samples
88 and patchcord test samples) used in the various tests to avoid confusion;
89 c) updated fibre naming conventions according to IEC 60793-2-50 and added provision for B-
90 657 fibres;
oSIST prEN IEC 61753-021-03:2025
IEC CDV 61753-021-03 ED1 © IEC 2025 4 86B/5006/CDV
91 d) added all the attenuation and return loss grades defined in IEC 61753-1;
92 e) removed the static side load test;
93 f) add provisions for rectangular ferrule connectors;
94 g) added the fibre optic connector proof test with static load – side pull;
95 h) added Annex B for visual examination of the outer cable sheath movement of reinforced
96 cables as an additional requirement for change of temperature, cable retention and flexing
97 of the strain relief tests.
98 The text of this International Standard is based on the following documents:

129 1 Scope
130 This part of IEC 61753 defines minimum initial test and measurement requirements and
131 severities which single-mode fibre optic connectors terminated as a pigtail or a patchcord satisfy
132 in order to be categorized as meeting the IEC standard category OP (outdoor protected
133 environment), as defined in IEC 61753-1.
134 If tests were performed on the connectors terminated as pigtails or patchcords for category
HD, HD
135 OP OP+ or OP+ and the product passed, the product will be automatically qualified or
136 categorized as meeting the IEC standard for category OP. If tests are performed on the
137 connectors terminated as pigtails or patchcords for category OP, and the product passes, the
138 product will be automatically qualified or categorized as meeting the IEC standard for category
HD
