Optical amplifiers - Part 4: Multichannel applications - Performance specification template

IEC 61291-4:2011 applies to optical amplifier (OA) devices and sub-systems to be used in multichannel applications. For single channel applications, use IEC 61291-2. The object of this performance specification template is to provide a frame for the preparation of detail specifications on the performances of OA devices and sub-systems to be used in multichannel applications. This third edition cancels and replaces the second edition published in 2008 and constitutes a technical revision. The main significant changes are the transient parameter test methods, IEC 61290-4 series, have been added to Tables 1, 2, and 3. This publication is to be read in conjunction with IEC 61291-1:2006.

Cette publication doit être lue conjointement avec la CEI 61291-1:2006.

Optični ojačevalniki - 4. del: Uporaba z več kanali - Šablona specifikacije izvedbe (IEC 61291-4:2011)

Ta del standarda IEC 61291 se uporablja za optične ojačevalnike (OA) in podsisteme, ki se uporabljajo z več kanali. Za enokanalne aplikacije se uporablja IEC 61291-2. Cilj te šablone specifikacije izvedbe je zagotoviti okvir za pripravo podrobnih specifikacij za izvedbe naprav z optičnim ojačevalnikom in podsistemov, ki se uporabljajo z več kanali. Avtorji podrobne specifikacije izdelka lahko dodajo specifikacijske parametre in/ali skupine specifikacijskih parametrov za določene aplikacije. Vendar avtorji podrobnih specifikacij ne smejo odstraniti specifikacijskih parametrov, določenih v tem standardu.

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 61291-4 has been prepared by subcommittee 86C: Fibre optic
systems and active devices, of IEC technical committee 86: Fibre optics.
This third edition cancels and replaces the second edition published in 2008 and constitutes a
technical revision. The main significant changes are the following:
The transient parameter test methods, IEC 61290-4 series, have been added to Tables 1, 2,
and 3.

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 publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
This standard is to be used in conjunction with IEC 61291-1.
A list of all parts in the IEC 61291 series, published under the general title Optical amplifiers,
can be found on the IEC website.
The committee has decided that the contents of this publication will remain unchanged until the
stability 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.

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 editions 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 abbreviations used in this International Standard is given in 3.3.
