EN 62496-2:2017

Optical circuit boards - Basic test and measurement procedures - Part 2: General guidance for definition of measurement conditions for optical characteristics of optical circuit boards

IEC 62496-2:2017(E) specifies a method of defining the conditions for measurements of optical characteristics of optical circuit boards. The method comprises the use of code reference look-up tables to identify different critical aspects of the measurement environment. The values extracted from the tables are used to construct a measurement identification code, which, in itself, captures sufficient information about the measurement conditions, so as to ensure consistency of independently measured results within an acceptable margin. Recommended measurement conditions are specified to minimise further variation in independently measured results. Keywords: bandwidth density, optical characteristics of optical circuit boards

Cartes à circuits optiques - Procédures fondamentales d'essais et de mesures - Partie 2: Recommandations générales relatives à la détermination des conditions de mesure des caractéristiques optiques des cartes à circuits optiques

IEC 62496-2:2017 spécifie une méthode pour définir les conditions de mesure des caractéristiques optiques des cartes à circuits optiques. La méthode inclut l'utilisation de tableaux présentant des références à des codes pour identifier différents aspects critiques de l'environnement de mesure. Les valeurs extraites des tableaux sont utilisées pour construire un code d'identification des mesures qui contient suffisamment d'informations sur les conditions de mesure, afin d'assurer la cohérence des résultats mesurés de manière indépendante avec une marge acceptable. Des conditions de mesure recommandées sont spécifiées pour réduire le plus possible les variations des résultats mesurés de manière indépendante. Mots clés: densités de largeur de bande, caractéristiques optiques des cartes à circuits optiques

Plošče z optičnimi vezji - Osnovni preskusni in merilni postopki - 2. del: Splošno navodilo za definiranje pogojev za določanje optičnih značilnosti plošč z optičnimi vezji (IEC 62496-2:2017)

Ta del standarda IEC 62496 določa metodo za definiranje pogojev za določanje optičnih značilnosti plošč z optičnimi vezji. Metoda vključuje uporabo referenčnih tabel za iskanje kode za identifikacijo različnih kritičnih vidikov merilnega okolja.
Vrednosti, pridobljene iz tabel, se uporabljajo za izdelavo merilne identifikacijske kode, ki sama po sebi zajema zadostne informacije o pogojih merjenja, da se zagotovi skladnost neodvisno izmerjenih rezultatov znotraj sprejemljivih omejitev. Priporočeni pogoji merjenja so določeni, da se zmanjšajo nadaljnje razlike v neodvisno izmerjenih rezultatih.
