Optical amplifiers - Part 5: Polarization mode dispersion parameter - General information

Applies to all commercially available optical amplifiers (OAs) including those using fibres (OFAs), semiconductors (SOAs), and waveguides (POWA), as classified in IEC 61292-3. This Technical Report presents general information about polarization mode dispersion (PMD), related to the application of the two commonly used methods to test PMD in OAs, the Jones matrix eigenanalysis (JME) and the Poincaré sphere analysis (PSA). This report is complementary to the International Standards describing the JME procedure (IEC 61290-11-1) and the PSA procedure (IEC 61290-11-2).

General information
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.

The main task of IEC technical committees is to prepare International Standards. However, a

technical committee may propose the publication of a Technical Report when it has collected

data of a different kind from that which is normally published as an International Standard, for

example "state of the art".

IEC 61292-5, which is a Technical Report, has been prepared by subcommittee 86C: Fibre

optic systems and active devices, of IEC technical committee 86: Fibre optics.
The text of this Technical Report is based on the following documents:
Enquiry draft Report on voting
86C/579A/DTR 86C/608/RVC

Full information on the voting for the approval of this Technical Report can be found in the

report on voting indicated in the above table.
---------------------- Page: 5 ----------------------
– 4 – TR 61292-5 ” IEC:2004(E)

IEC 61292 consists of the following parts, under the new general title Optical amplifiers:

Part 1: Parameters of amplifier components
Part 2: Theoretical background for noise figure evaluation using the electrical
spectrum analyzer
Part 3: Classification, characteristics and applications.

Part 4: Maximum permissible optical power for the damage-free and safe use of optical

amplifiers, including Raman amplifiers
Part 5: Polarization mode dispersion parameter – General information

Future standards in this series will carry the new general title as cited above. Titles of existing

standards in this series will be updated at the time of the next edition.

This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.

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.
A bilingual version of this publication may be issued at a later date.

General information
1 Scope

This part of IEC 61292, which is a Technical Report, applies to all commercially available

optical amplifiers (OAs) including those using fibres (OFAs), semiconductors (SOAs), and

waveguides (POWA), as classified in IEC 61292-3.

This Technical Report presents general information about polarization mode dispersion (PMD),

related to the application of the two commonly used methods to test PMD in OAs, the Jones

matrix eigenanalysis (JME) and the Poincaré sphere analysis (PSA), which have been

demonstrated to be formalistically equivalent [4,5] .

This report is complementary to the International Standards describing the JME procedure

(IEC 61290-11-1) and the PSA procedure (IEC 61290-11-2).
2 Normative references

PMD refers to how the polarized light and in particular the principal states of polarization

(PSPs) from a short pulse of a narrowband light source are modified when going through a

device such as an OA. This process is mathematically explained b
