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

and mean attenuation for random mated optical connectors.
2 Normative references
The following referenced documents are indispensable for the application of this document.

3 General description
3.1 Test methods
Two test methods are described for measuring the attenuation of random mated optical
connectors. Both provide an estimate of the expected average performance that a group of
patchcords (including adaptors, if applicable) selected from a batch will exhibit when utilised
in an optical system. The patchcords, and any adaptors, must be chosen at random to ensure
that the measurements provide a statistically unbiased estimate.
Method 1 describes the procedure based on the use of 10 patchcords (20 optical connectors)
and 10 adaptors. In this case all of the plugs are sequentially used as “reference” plugs and
all of the remaining plugs are tested against them. The result is based on 360 measurements
as indicated in the test matrix shown in Figure 3.
Method 1 is intended to be part of a design approval exercise that may involve one or more
suppliers. Once approval is achieved, Method 2 would be relied on to maintain process
control. However, in the event of a dispute, Method 1 shall act as the reference measurement
method.
Method 2 describes a procedure based on the measurement of 15 patchcords.
Five patchcords are selected as “reference” patchcords, with one plug on each of the
patchcords being nominated as a “reference” plug. All plugs of the remaining 10 patchcords
are then tested against each of the five “reference” plugs. This produces 100 measurements
as indicated in the test matrix shown in Figure 6.
– 6 – 61300-3-34 © IEC:2009(E)
It is recognised that the number of measurements required by Method 1 may be excessive for
day-to-day routine checking of either in-house or supplier produced products. In this case, as
indicated above, Method 2 may be used as an alternative option.
NOTE In this measurement method, the terms “reference” plug or “reference” patchcord are used to define those
components chosen at random from a batch, against which a number of comparative measurements are made. It is
not intended that the terms should imply specially chosen or manufactured components, such as those used, for
example, in screen testing.
3.2 Precautions
The following test requirements shall be met:
3.2.1
Precautions shall be taken to ensure that the cladding modes do not affect the measurement.
Cladding modes shall be stripped as a function of the fibre coating.
3.2.2
Precautions shall be taken to ensure the position of the fibres in the test remains fixed
between the measurement of P and P to avoid changes in attenuation due to bending losses.
1 2
3.2.3
The stability performance of the test equipment shall be ≤0,05 dB or 10 % of the attenuation
to be measured, whichever is the lower value. The stability shall be maintained over the
measurement time and operational temperature range. The required measurement resolution
shall be 0,01 dB for both multimode and singlemode.
3.2.4
To achieve consistent results, clean and inspect all connectors and adaptors prior to
measurement. Visual examination shall be undertaken in accordance with IEC 61300-3-1.
3.2.5
The power in the fibre shall be at a level that does not generate non-linear scattering effects.
