SIST EN IEC 61290-4-4:2018

Optical amplifiers - Test methods - Part 4-4: Gain transient parameters - Single channel optical amplifiers with gain control (IEC 61290-4-4:2018)

This part of IEC 61290-4 applies to optical amplifiers (OAs) and optically amplified elementary
sub-systems. More specifically, it applies to OAs using active fibres (optical fibre amplifiers,
OFAs) containing rare-earth dopants, such as erbium doped fibre amplifiers (EDFAs),
presently commercially available, as indicated in IEC 61291-1.
This document provides the general background for optical amplifier gain transients and their
measurements and indicates those IEC standard test methods for accurate and reliable
measurements of the following transient parameters:
a) optical input power increase/decrease transient gain overshoot and transient net gain
overshoot;
b) optical input power increase/decrease transient gain undershoot and transient net gain
undershoot;
c) optical input power increase/decrease gain offset;
d) optical input power increase/decrease transient gain response constant (settling time).
These parameters have been included to provide a complete description of the transient
behaviour of gain controlled OA. The parameters defined here are applicable if the amplifier is
an OFA or an alternative type of OA.

Amplificateurs optiques - Méthodes d'essai - Partie 4-4: Paramètres de gain transitoire - Amplificateurs optiques monocanaux avec commande de gain

IEC 61290-4-4:2018 s’applique aux amplificateurs optiques (OA: optical amplifier) et aux sous-systèmes élémentaires à amplification optique. Plus précisément, elle s’applique aux amplificateurs optiques utilisant des fibres actives (amplificateurs à fibres optiques, OFA: optical fibre amplifier), contenant des dopants aux terres rares, tels que les amplificateurs à fibre dopée à l'erbium (EDFA: erbium doped fibre amplifier), actuellement disponibles sur le marché, comme l’indique l'IEC 61291-1. Le présent document fournit le contexte général pour les gains transitoires des amplificateurs optiques et leurs mesures et décrit des méthodes d'essai normalisées de l'IEC pour effectuer des mesures précises et fiables des paramètres des transitoires suivants:
a) dépassement positif du gain transitoire lors d'une augmentation ou d'une diminution de puissance optique d'entrée et dépassement positif du gain net transitoire;
b) dépassement négatif du gain transitoire lors d'une augmentation ou d'une diminution de puissance optique d'entrée et dépassement négatif du gain net transitoire;
c) décalage de gain lors d'une augmentation ou d'une diminution de puissance optique d'entrée;
d) constante de temps de réponse du gain transitoire lors d'une augmentation ou d'une diminution de puissance optique d'entrée (temps de stabilisation).
Ces paramètres ont été inclus pour fournir une description complète du comportement des transitoires d'un amplificateur optique avec commande de gain. Les paramètres définis ici sont applicables si l'amplificateur est un amplificateur à fibres optiques ou un amplificateur optique d'un type alternatif.

Optični ojačevalniki - Preskusne metode - 4-4. del: Prehodni parametri ojačenja - Enokanalni optični ojačevalniki s krmiljenjem ojačenja (IEC 61290-4-4:2018)

Ta del standarda IEC 61290-4 se uporablja za optične ojačevalnike (OA) in optično ojačane osnovne podsisteme. Natančneje se uporablja za optične ojačevalnike z uporabo aktivnih vlaken (ojačevalnike z optičnimi vlakni, OFA), ki vsebujejo redke zemeljske dopante, kot so ojačevalniki z vlakni, dopiranimi z erbijem (EDFA), ki so trenutno komercialno razpoložljivi, kot je navedeno v standardu IEC 61291-1.
Ta dokument zagotavlja splošno ozadje za ojačanje moči optičnih ojačevalnikov in njihove meritve ter določa standardne preskusne metode IEC, ki zagotavljajo natančne in zanesljive meritve naslednjih parametrov ojačanja:
a) povečanje/zmanjšanje presežnega prehodnega ojačenja in presežnega prehodnega neto ojačenja optične vhodne moči;
b) povečanje/zmanjšanje nedoseženega prehodnega ojačenja in nedoseženega prehodnega neto ojačenja optične vhodne moči;
c) povečanje/zmanjšanje prehodne izravnave optične vhodne moči;
d) povečanje/zmanjšanje konstante odziva prehodnega ojačenja optične vhodne moči (odzivni čas).
Ti parametri so bili vključeni z namenom zagotovitve popolnega opisa ojačevalnega vedenja optičnega ojačevalnika (OA) s krmiljenjem moči. Tukaj opredeljeni parametri veljajo, če je ojačevalnik tipa OFA ali tipa OA.

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 61290-4-4 has been prepared by subcommittee 86C: Fibre optic
systems and active devices, of IEC technical committee 86: Fibre optics.
The text of this International Standard is based on the following documents:
