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 61753-053-3 has been prepared by sub-committee 86B: Fibre
optic interconnecting devices and passive components, of IEC technical committee 86: Fibre
optics.
The text of this standard is based on the following documents:

Uncontrolled environment
Part 2-3: Non-connectorised single-mode 1×N and 2×N non-wavelength-selective
branching devices for Category U – Uncontrolled environment
Part 021-2 Fibre optic connectors terminated on single-mode fibre to category C –
Controlled environment
Part 022-2: Fibre optic connectors terminated on multimode fibre for category C –
Controlled environment
Part 051-3: Single-mode fibre, plug-style fixed attenuators for Category U – Uncontrolled
environment
Part 052-3: Single-mode fibre, pigtailed-style fixed attenuators for category U –
Uncontrolled environment

1 Scope
This part of IEC 61753 contains the minimum initial test and measurement requirements and
severities which a fibre optic attenuator must satisfy in order to be categorised as meeting the
requirements of single mode fibre pigtailed style continuously variable attenuator devices
used in uncontrolled environments.
