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.
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 61300-2-1 has been prepared by subcommittee 86B: Fibre optic
interconnecting devices and passive components, of IEC technical committee 86: Fibre optics.
This third edition of IEC 61300-2-1 cancels and replaces the second edition published in 2003
and constitutes a technical revision. Changes from the previous edition are to reconsider the
severity and the structure of this standard.

The text of this standard is based on the following documents:
FDIS Report on voting

voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
A list of all parts of IEC 61300 series, published under the general title Fibre optic
interconnecting devices and passive components – Basic test and measurement procedures
can be found on the IEC website.
The committee has decided that the contents of this publication will remain unchanged until the
maintenance result date indicated on the IEC web site under "http://webstore.iec.ch" in the data
related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
The contents of the corrigendum of January 2010 have been included in this copy.

IMPORTANT – The “colour inside” logo on the cover page of this publication indicates
that it contains colours which are considered to be useful for the correct understanding
of its contents. Users should therefore print this publication using a colour printer.

Part 2-1: Tests –
Vibration (sinusoidal)
1 Scope
This part of IEC 61300 evaluates the effects of vibration on fibre optic devices at the
predominant frequency ranges and magnitudes that may be encountered during field service.
NOTE Most vibrations encountered in service are not of a simple harmonic nature. However, it has been shown
that tests based on vibrations of this type are satisfactory to simulating actual service.

3 General description
This procedure is derived from IEC 60068-2-6, test Fc. The device under test (DUT) is
mounted on a vibration generator and vibrated with a sinusoidal motion. The DUT is exposed to
vibration in three mutually perpendicular directions, one of which is parallel to the optical axis.
The vibration amplitude is specified either in terms of constant displacement or constant
acceleration.
4 Apparatus
4.1 General
The apparatus shall be in accordance with IEC 60068-2-6, test Fc and consists of the following
elements.
– 6 – 61300-2-1 © IEC:2009
4.2 Vibration generator
A vibration generator capable of generating a sinusoidal excitation and its auxiliary test
equipment.
4.3 Mounting fixture
A suitable DUT mounting fixture capable of transmitting the vibration conditions specified shall
be used. The mounting fixture shall be designed so that the resonant vibration inherent in the
fixture shall not have an effect on the specified frequency range. The amplitude and the
acceleration of the applied vibration shall be monitored on the test fixture near the DUT
mounting points.
4.4 Measuring equipment
Unless otherwise specified, measuring equipment specified in IEC 61300-3-3 shall be
connected to the DUT for monitoring the optical performances during the test; moreover the
transient loss measuring equipment specified in IEC 61300-3-28 shall be used to detect fast
variation of attenuation.
5 Procedure
5.1 Preparation of DUT
Prepare the DUT according to the manufacturer’s instructions or as specified in the relevant
specification.
5.2 Pre-conditioning
Pre-condition the DUT for 2 h at the standard test conditions specified in IEC 61300-1, unless
otherwise specified in the relevant specification.
5.3 Initial measurement
Complete initial examinations and measurements of the DUT as required by the relevant
specification.
5.4 Conditioning
The DUT shall be mounted rigidly to the fixture in a manner that simulates normal mounting as
closely as possible. A minimum of 200 mm of optical fibre/cable shall be unsupported on both
ends of the DUT and be attached free of tension to the vibrating surface. Conduct the
procedure in accordance with IEC 60068-2-6, test Fc. The DUT shall be vibrated in three
mutually perpendicular axes coincident with the principal axes of the device. If the sample has
axial symmetry the number of axes to be tested can be reduced to two. The vibration
endurance shall be performed by sweeping continuously between minimum and maximum
frequency at a specified rate. An example of vibration apparatus test is outlined in Figure 1.
5.5 Monitoring
The attenuation and/or return loss of the DUT shall be monitored during the test using an x-y-
plotter, an oscilloscope or/and a digital data acquisition system for recording as described in
IEC 61300-3-28, unless otherwise specified in the relevant specification. Any change in optical
performance shall be within the limit given in the relevant specification.

5.6 Recovery
Allow the DUT to remain under standard test conditions for 2 h, as defined in IEC 61300-1,
unless otherwise specified in the relevant specification. Clean the DUT in accordance with the
manufacturer’s instructions.
5.7 Final measurements
On completion of the test, remove all fixtures and make final measurements, as defined by the
relevant specification, to ensure that there is no permanent damage to the DUT. The results of
the final measurement shall be within the limit established in the relevant specification.
Unless otherwise specified, visually examine the DUT in accordance with IEC 61300-3-1.
