FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical reports or guides and they are accepted by the National Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61300-3-12 has been prepared by subcommittee 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:
FDIS Report on voting
86B/842/FDIS 86B/943/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
IEC 1300 consists of the following parts, under the general title Fibre optic interconnecting

1 General
1.1 Scope and object
This part of IEC 1300 describes the test to determine the dependence of attenuation of single-
mode fibre optic components to changes in the state of the polarization of the input light. The
value given by this test is the maximum variation in loss over all states of polarization of the
launch light into the component under test (DUT).
1.2 Normative reference
The following normative document contains provisions which, through reference in this text,
constitute provisions of this part of IEC 1300. At the time of publication, the edition indicated
was valid. All normative documents are subject to revision, and parties to agreements based
on this part of IEC 1300 are encouraged to investigate the possibility of applying the most
recent edition of the normative document indicated below. Members of IEC and ISO maintain
registers of currently valid International Standards.
IEC 1300-3-2: 1995, Fibre optic interconnecting devices and passive components – Basic test
and measurement procedures – Part 3-2: Examinations and measurements – Polarization
dependence of a single-mode fibre optic device
2 General description
This test differs from the methods described in IEC 1300-3-2 and it constitutes an alternative
method. These other test procedures are based on manipulation of the state of polarization of
light either continuously or in small incremental adjustments in order to measure maxima and
minima of the attenuation of transmitted light. This test method involves the measurement of
the behaviour of a DUT when illuminated by a small set of well-defined states of polarization of
input light. These measurements are followed by a matrix calculation to determine the
polarization dependence of loss (PDL) of the DUT.
This procedure can be applied to any single-mode passive component. It determines the total
range of attenuation due to changes in polarization of the launch light.
Generally, there are two matrix formalisms to describe and quantify the polarization behaviour
of light in fibre optic systems, that based on the Mueller matrix and that based on the Jones
matrix.
The Mueller matrix formalism entails an optical power representation of the performance of
components. This matrix is a square 16 element matrix. Here, the state of polarization of light
is described as a 4 element Stokes vector. The Stokes vector of the incident light multiplied by
the Mueller matrix of the DUT gives the Stokes vector of the output light, and this output light
may be from transmission, reflection or scattering. In the determination of PDL of a component
using Mueller matrices, i
