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.
International Standard IEC 61753-056-2 has been prepared by subcommittee SC86B: Fibre
optic interconnecting devices and passive components, of IEC technical committee TC86:
Fibre optics.
The text of this standard is based on the following documents:

INTRODUCTION
1) The International Electrotechnical Commission (IEC) draws attention to the fact that it is
claimed that compliance with this document may involve the use of a patent concerning
optical fuse.
IEC takes no position concerning the evidence, validity and scope of this patent right.
The holder of this patent right has assured the IEC that he/she is willing to negotiate
licences either free of charge or under reasonable and non-discriminatory terms and
conditions with applicants throughout the world. In this respect, the statement of the
holder of this patent right is registered with IEC. Information may be obtained from:
KiloLambda technologies, Ltd.
22a Wallenberg street,
Tel-Aviv 69719,
Israel
Attention is drawn to the possibility that some of the elements of this document may be the
subject of patent rights other than those identified above. IEC shall not be held
responsible for identifying any or all such patent rights.
ISO (www.iso.org/patents) and IEC (http://patents.iec.ch) maintain on-line data bases of
patents relevant to their standards. Users are encouraged to consult these data bases for
the most up-to-date information concerning patents.
US patent US-7162,114 B2, Optical Energy switching device and method", granted
January 9, 2007.
Japan patent 4376632, Optical Energy switching device and method", granted September
18, 2009.
2) The optical fuse is a passive device, designed to protect equipment and fibre cables from
damage due to optical overpower, spikes and surges. The optical fuse produces a
controlled, permanent, signal blocking at a predetermined power threshold in an optical
fibre transmission line. The optical fuse is wavelength independent over its entire specified
spectral range. IEC 60869-1 contains generic information on optical fuses. The optical
fuse has a maximum allowed power input P . Beyond this power it is dysfunctional
in max
and can let light through. Numerical values for P are given in Annex B.

Controlled environment
1 Scope
This part of IEC 61753 contains the minimum initial test and measurement requirements and
severities which a fibre optical fuse satisfies in order for it to be categorised as meeting the
requirements of single mode fibre pigtailed style optical fuse used in controlled environments.
Optical performance specified in this document relates to in-line type configurations fuses
only.
