Annotation of standard text IEC 61280-1-4-ed.3.0 :
IEC 61280-1-4:2023 establishes the characterization process of the encircled flux measurement method of light sources intended to be used with multimode fibre. This document sets forth a procedure for the collection of two-dimensional fibre optic nearfield greyscale data and subsequent reduction to one-dimensional data expressed as a set of three sampled parametric functions of radius from the fibre’s optical centre. Estimation of the fibre core diameter is not an objective of this document. This third edition cancels and replaces the second edition published in 2009. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - improvement of calibration procedure and calibration traceability; - improvement of fibre shaker description and requirements; - addition of pulsed light sources; - removal of a poorly traceable calibration process using a micro positioner. LIEC 61280-1-4:2023 stipule le processus de caracterisation de la methode de mesure du flux inscrit de sources optiques destinees a etre utilisees avec des fibres multimodales. Le present document definit une procedure consistant a collecter des donnees fibroniques de champ proche, bidimensionnelles et en niveaux de gris, puis a les reduire en donnees unidimensionnelles exprimees sous la forme d’un ensemble de trois fonctions parametriques echantillonnees du rayon par rapport au centre optique de la fibre. Cette troisieme edition annule et remplace la deuxieme edition parue en 2009. Cette edition constitue une revision technique. Cette edition inclut les modifications techniques majeures suivantes par rapport a l’edition precedente: - amelioration de la procedure et de la tracabilite de l’etalonnage; - amelioration de la description et des exigences relatives a l’agitateur de fibre; - ajout des sources optiques pulsees; - suppression d’un processus d’etalonnage utilisant un micropositionneur, en raison de sa faible tracabilite.
