Fibre optic interconnecting devices and passive components - Basic test and measurement procedures - Part 3-2: Examination and measurements - Polarisation dependent loss in a single-mode fibre optic device (IEC 61300-3-2:2009)

This part of IEC 61300 specifies measurement methods to determine the dependence of loss in a single-mode fibre optic device to changes in polarization. This procedure focuses on measurements with a fixed wavelength source; therefore, this procedure is applicable to devices whose properties at a single wavelength can represent those over the broader wavelength band. Typical examples of such devices are single-mode interconnecting devices and passive components, including connectors, splices, branching devices, attenuators, isolators, and switches. The maximum observed variation in transmission loss is referred to as polarization-dependent-loss (PDL). This standard applies to broadband devices and not to narrow-band devices like filters and multiplexers. The reader is referred to IEC 61300-3-29 for such measurements.

La CEI 61300-3-2:2009 spécifie des méthodes de mesure permettant de déterminer la dépendance de la perte d'un dispositif pour fibres optiques unimodales aux variations de polarisation. La présente procédure porte sur les mesures comportant une source de longueurs d'onde fixe; de ce fait, cette procédure est applicable aux dispositifs dont les propriétés, à une longueur d'onde unique, peuvent représenter celles situées sur une bande de longueurs d'onde plus large. A titre d'exemples typiques de tels dispositifs, on peut citer les dispositifs d'interconnexion et composants passifs unimodaux, y compris les connecteurs, les épissures, les dispositifs de couplage, les affaiblisseurs, les isolateurs et les commutateurs. La variation de perte de transmission observée maximale est désignée sous le terme de perte dépendant de la polarisation (PDL, polarization-dependent-loss). La présente norme s'applique aux dispositifs à large bande et non pas aux dispositifs à bande étroite comme les filtres et les multiplexeurs. Le lecteur est invité à se référer à la CEI 61300-3-29 pour de telles mesures. Cette troisième édition annule et remplace la deuxième édition parue en 1999 et constitue une révision technique. Les modifications principales par rapport à l'édition précédente sont: la présente édition comprend la méthode tous états de l'édition antérieure ainsi que la méthode de la matrice de Mueller décrite dans la CEI 61300-3-12.

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 61300-3-2 has been prepared by subcommittee 86B: Fibre optic
interconnecting devices and passive components, of IEC technical committee 86: Fibre optics.
This third edition cancels and replaces the second edition published in 1999. It constitutes a
technical revision.
The main changes with respect to the previous edition are listed below:
• This edition includes both the all-states method of the previous edition as well as the
Mueller matrix method from IEC 61300-3-12.

Polarization dependent loss in a single-mode fibre optic device



1 Scope
This part of IEC 61300 specifies measurement methods to determine the dependence of loss
in a single-mode fibre optic device to changes in polarization. This procedure focuses on
measurements with a fixed wavelength source; therefore, this procedure is applicable to
devices whose properties at a single wavelength can represent those over the broader
wavelength band. Typical examples of such devices are single-mode interconnecting devices
and passive components, including connectors, splices, branching devices, attenuators,
isolators, and switches. The maximum observed variation in transmission loss is referred to as
polarization-dependent-loss (PDL).
This standard applies to broadband devices and not to narrow-band devices like filters and
multiplexers. The reader is referred to IEC 61300-3-29 for such measurements.
2 Normative references
The following referenced documents are indispensable for the application of this document.
For dated references, only the edition cited applies. For undated references, the latest edition
of the referenced document (including any amendments) applies.

and measurement procedures – Part 3-29: Examinations and measurements – Measurement
techniques for characterising the amplitude of the spectral transfer function of DWDM
components
3 Measurement methods
Two methods for measuring polarization-dependent-loss are described. The all states method
determines the maximum variation in transmission loss by stimulating with a representative
set of all possible polarization states including linear, circular, and elliptical. The Mueller
matrix method determines the sensitivity using a set of fixed states and applying the Mueller
matrix mathematical analysis.
This procedure originally consisted of only one method, but has been updated to incorporate
1
the technique previously described by IEC 61300-3-12 . That standard will be discontinued.
3.1 All states method
In this method, the PDL is determined by rotating the source polarization over a
representative set of all possible polarization states while monitoring the transmission

response of the device using a power meter. The rotation can be accomplished in either a
deterministic or a pseudo-random fashion.
The term “deterministic” refers to techniques that scan a large subset of the entire polarization
state space in a repeatable way. This method scans the Poincaré sphere along predetermined
trajectories to produce a good approximation of full sphere coverage.
The term “pseudo-random” refers to techniques that scan the polarization through a pseudo-
random variation of retardance in the optical path, usually using the distributed retardance of
optical fibre loops in motion.
Figure 1 shows the difference in coverage between the two techniques. In either case, the
accuracy of the method is dependent on the degree of coverage over the Poincaré sphere due
to the combination of the states generated by the polarization controller and the response
time of the power detector with respect to the polarization scan rate.

3.2 Mueller matrix method
The Mueller matrix method involves the measurement of the behaviour of a device under test,
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 PDL of the DUT.
Generally, there are two matrix formalisms that can describe and quantify the polarization
behaviour of light based on Mueller and Jones calculus respectively. For fully polarized light,
as required for the PDL measurements, the Mueller and Jones formalisms are equivalent.
Since measurements with polarization instrumentation on only one side of the DUT directly
obtain the necessary elements of the Mueller matrix, that is elements corresponding to power
ratios rather than field amplitude and phase, the test procedure described here uses Mueller
mathematics to determine PDL.
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 (SOP)
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 Stok
