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 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. Keywords: optical amplifiers (OAs) gain transients

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. Mots clés: amplificateurs optiques gains transitoires

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.
