FIBRE OPTIC INTERCONNECTING DEVICES AND PASSIVE COMPONENTS –
MECHANICAL SPLICES AND FUSION SPLICE PROTECTORS
FOR OPTICAL FIBRES AND CABLES –

Part 1: Generic specification


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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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.
International Standard IEC 61073-1 has been prepared by subcommittee 86B: Fibre optic
interconnecting devices and passive components, of IEC technical committee 86: Fibre optics.
This fourth edition cancels and replaces the third edition published in 1999. This edition
constitutes a technical revision. The main changes with respect to the previous edition are as
follows:
• terms and definitions have been reconsidered;
• style has been added in classification of requirement;
• environmental category has been deleted from classification of requirement;
• standardisation structure and standards interlink have been reconsidered.

4.1.6 Normative reference extensions
Normative reference extensions are utilised to identify integration of independent standards
specifications or other reference documents into blank detail specifications.
Unless specified exception is noted, additional requirements imposed by an extension are
mandatory. Usage is primarily intended to merge associated components to form hybrid
devices, or can involve integrated functional application requirements that are dependent on
technical expertise other than fibre optics.
Published reference documents produced by ITU consistent with the scope statements of the
relevant IEC specification series may be utilised as extensions. Published documents produced
by other regional standardisation bodies such as TIA, ETSI, JIS, etc., may be referenced in an
informative annex attached to the generic specification.
Some optical fibre splice configurations require special qualification provisions that are not
necessary to impose universally. These accommodate individual component design
configurations, specialised field tooling, or specific application processes. In such cases,
requirements may be necessary to assure repeatable performance or adequate safety, and
provide additional guidance for complete product specification. These extensions are
mandatory whenever utilised to prepare, assemble or install an optical fibre splice, either for
field application usage or preparation of qualification test specimens. The relevant specification
shall clarify all stipulations. However, design- and style-dependent extensions shall not b
