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
48 international co-operation on all questions concerning standardization in the electrical and electronic fields. To
49 this end and in addition to other activities, IEC publishes International Standards, Technical S pecifications,
50 Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
51 Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
52 in the subject dealt with may participate in this preparatory work. International, governmental and non-
53 governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
54 with the International Organization for Standardization (ISO) in accordance with conditions determined by
55 agreement between the two organizations.
56 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
57 consensus of opinion on the relevant subjects since each technical committee has representation from all
58 interested IEC National Committees.
59 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
60 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
61 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
62 misinterpretation by any end user.
63 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
64 transparently to the maximum extent possible in their national and regional publications. Any divergence
65 between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
66 the latter.
67 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
68 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
69 services carried out by independent certification bodies.
70 6) All users should ensure that they have the latest edition of this publication.
71 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
72 members of its technical committees and IEC National Committees for any personal injury, property damage or
73 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
74 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
75 Publications.
76 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
77 indispensable for the correct application of this publication.
78 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
79 patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
80 International Standard IEC 61300-3-50 has been prepared by subcommittee 86B: Fibre optic
81 interconnecting devices and passive components, of IEC technical committee 86: Fibre optics.
82 This second edition cancels and replaces the first edition published in 2013 and constitutes a
83 technical revision.
84 This edition includes the following significant technical changes with respect to the previous
85 edition:
87 a.) including corrigenda 1 (January 2015) and corrigenda 2 (July 2015)
88 b.) revising structure of the document

94 Full information on the voting for the approval of this standard can be found in the report on
95 voting indicated in the above table.
96 This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
97 A list of all parts in the IEC 61300 series, published under the general title, Fibre optic
98 interconnecting devices and passive components – Basic test and measurement procedures

100 The committee has decided that the contents of this publication will remain unchanged until
101 the stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data
102 related to the specific publication. At this date, the publication will be
