Optical amplifiers - Test methods - Part 10-2: Multichannel parameters - Pulse method using a gated optical spectrum analyzer

Applies to optical fibre amplifiers (OFA) using active fibres, containing rare-earth dopants, currently commercially available. The object is to establish uniform requirements for accurate and reliable measurements of the signal-spontaneous noise figure as defined in IEC 61291-1.The test method described is, in general, for multichannel applications. Single-channel applications are a special case of multichannel applications. This second edition cancels and replaces the first edition. It is a technical revision with updated references and cautions on proper use of the procedure.

Amplificateurs optiques - Méthodes d'essai - Partie 10-2: Paramètres à canaux multiples - Méthode d'impulsion utilisant un analyseur de spectre optique stroboscopique

S'applique aux amplificateurs à fibres optiques (AFO) utilisant des fibres actives, dopées aux terres rares, qui sont actuellement disponibles sur le marché. Etablit des prescriptions uniformes en vue de mesures précises et fiables du facteur de bruit signal/émission spontanée défini en CEI 61291-1. La méthode d'essai décrite est, en général, destinée à des applications à canaux multiples. Les applications à canal unique constituent un cas spécial d'applications à canaux multiples. Cette seconde édition de la CEI 61290-10-2 annule et remplace la première édition. C'est une révision technique avec des références et des précautions relatives à l'utilisation convenable du procédé mises à jour.

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.
The International Electrotechnical Commission (IEC) draws attention to the fact that it is claimed that compliance
with this document may involve the use of two patents.
One patent concerns a technique for determining the amplified spontaneous emission noise of an optical amplifier
in the presence of an optical signal given in Clause 4 and Clause 6.
