IEC 61291-2:2012

Optical amplifiers - Part 2: Digital applications - Performance specification template

IEC 61291-2:2012 applies to single channel optical amplifier (OA) devices to be used in digital applications. For multichannel applications, use IEC 61291, Part 4. The object of this performance specification template is to provide a frame for the preparation of detail specifications on the performances of single channel OA devices to be used in digital applications. This edition constitutes a minor update through clarification that the scope is for single channel optical amplifiers, and that pump leakage parameters do not apply to semiconductor optical amplifiers.

Amplificateurs optiques - Partie 2: Applications numériques - Modèle de spécifications de performances

La CEI 61291-2:2012 s'applique aux dispositifs amplificateurs optiques (AO) à un seul canal, destinés à être utilisés dans le cadre d'applications numériques. Pour les applications multicanaux, utiliser la CEI 61291, Partie 4. L'objet de ce modèle de spécifications de performances est de fournir une trame de préparation de spécifications particulières relatives aux performances des dispositifs AO à un seul canal destinés à être utilisés dans le cadre d'applications numériques. Cette édition constitue une mise à jour mineure, consistant en une clarification du domaine d'application, mentionnant uniquement les amplificateurs optiques pour un seul canal, et les paramètres de fuite de pompage ne s'appliquent pas aux amplificateurs optiques à semiconducteurs.

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 61291-2 has been prepared by subcommittee 86C: Fibre optic
systems and active devices, of IEC technical committee 86: Fibre optics.
The text of this standard is based on the following documents:
CDV Report on voting
86C/1018/CDV 86C/1039/RVC

Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This third edition cancels and replaces the second edition published in 2007 and constitutes a
minor update through clarification that the scope is for single channel optical amplifiers, and
that pump leakage parameters do not apply to semiconductor optical amplifiers.

INTRODUCTION
This international standard is devoted to the subject of optical amplifiers. The technology of
optical amplifiers is still rapidly evolving, hence amendments and new additions to this
standard can be expected. Each abbreviation introduced in this international standard is
generally explained in the text the first time it appears. However, for an easier understanding
of the whole text, a list of all abbreviations used in this international standard is given in
Clause 3.
