Le présent document s'applique uniquement aux fibres multimodales à coeur en verre à gradient d'indice (catégorie A1). Cette méthode d'essai, qui est généralement utilisée dans les installations de production et de recherche, n'est pas facilement réalisée sur le terrain. Ce document décrit une méthode de caractérisation de la structure modale d'une fibre multimodale à gradient d'indice. Cette information est utile pour évaluer les performances de largeur de bande d'une fibre, en particulier lorsque la fibre est destinée à supporter une variété de conditions d'injection telles que celles produites par les émetteurs laser normalisés.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
