| Prescriptions de qualité de service pour les noeuds optiques passifs: manchons étanches pour environnements extérieurs |
 |
La présente Recommandation porte sur les nœuds optiques passifs situés dans des environnements extérieurs. Elle traite des techniques de raccordement à l'aide de manchons ainsi que des modules d'agencement pour fibres, compte tenu des propriétés mécaniques, des caractéristiques du milieu ambiant ainsi que des caractéristiques des modules d'agencement pour fibres optiques.Les éléments suivants ont été ajoutés aux fins de la présente révision:- un programme de tests d'évaluation de la qualité de service des manchons optiques étanches dans deux environnements de base: en extérieur sous le niveau du sol (souterrain) (OS) ou en extérieur au-dessus du sol (OA);- la simulation de l'effet des interventions liées à la maintenance du réseau.Deux appendices ont été ajoutés:- une liste de contrôle pour la caractérisation systématique des produits, conformément à la Rec. UIT-T L.51;- une liste de spécifications additionnelles à prendre en considération dans des environnements particuliers (galeries, par exemple) ou en fonction des conditions locales. |
