Fibre optic interconnecting devices and passive components - Basic test and measurement procedures - Part 3-53: Examinations and measurements - Encircled angular flux (EAF) measurement method based on two-dimensional far field data from multimode waveguide (including fibre)

This part of IEC 61300 defines the encircled angular flux measurement of multimode waveguide light sources, in which most of the transverse modes are excited. The term "waveguide" is understood to include both channel waveguides and optical fibres but not slab waveguides. The applicable fibre types are the followings: - A1 specified in IEC 60793-2-10; - A3 specified in IEC 60793-2-30; - A4 specified in IEC 60793-2-40.

IEC 61300-3-53:2020 est disponible sous forme de IEC 61300-3-53:2020 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'�dition pr�c�dente.L'IEC 61300-3-53:2020 définit la mesure du flux angulaire inscrit de sources de rayonnement lumineux dotées d’un guide d’ondes multimodal, pour lequel la plupart des modes transversaux sont excités. On considère que le terme "guide d’ondes" inclut à la fois des guides d’ondes de canal et des fibres optiques, mais pas des guides d’ondes rectangulaires rigides. Les types de fibres applicables sont les suivants: - A1 spécifié dans l’IEC 60793-2-10; - A3 spécifié dans l’IEC 60793-2-30; - A4 spécifié dans l’IEC 60793-2-40. Cette deuxième édition annule et remplace la première édition parue en 2015. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: - la portée des guides d’ondes applicables, ainsi que la fibre et le guide d’ondes optiques multimodaux à gradient d’indice ont été inclus; - restructuration de 5.3; - ajout de l'Annexe C et de l'Annexe D.

Ta del standarda IEC 61300 opredeljuje merjenje obdanega koničastega pretoka svetlobnih virov večrodovnega valovoda, v katerem je vzbujena večina transverzalnih rodnih tipov. Izraz »valovod« zajema kanalske valovode in optična vlakna, ne pa tudi ploščatih valovodov.
Uporabljajo se naslednje vrste vlaken:
- A1, kot je določeno v standardu IEC 60793-2-10;
- A3, kot je določeno v standardu IEC 60793-2-30;
- A4, kot je določeno v standardu IEC 60793-2-40.
