Fibre optic communication subsystem test procedures - Part 2-8: Digital systems - Determination of low BER using Q-factor measurements
IEC 61280-2-8:2021 is available as IEC 61280-2-8:2021 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition. IEC 61280-2-8:2021 specifies two main methods for the determination of low BER values by making accelerated measurements. These include the variable decision threshold method (Clause 5) and the variable optical threshold method (Clause 6). In addition, a third method, the sinusoidal interference method, is described in Annex B. This second edition cancels and replaces the first edition published in 2003. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - correction of errors in Formula (8) in 5.5.2 and in a related formula in 5.5.3; - correction of errors in the references to clauses, subclauses, figures, procedures, and in the Bibliography; - alignment of the terms and definitions in 3.1 with those in IEC 61281-1.

IEC 61280-2-8:2021 est disponible sous forme de IEC 61280-2-8:2021 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente. L'IEC 61280-2-8:2021 spécifie deux méthodes principales permettant de déterminer de faibles valeurs de BER en réalisant des mesures accélérées. Ces méthodes utilisent soit un seuil de décision variable (Article 5), soit un seuil optique variable (Article 6). De plus, une troisième méthode fondée sur le brouillage sinusoïdal est décrite à l’Annexe B. Cette deuxième édition annule et remplace la première édition parue en 2003. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l’édition précédente: - correction d’erreurs dans la Formule (8) en 5.5.2 et dans une formule associée en 5.5.3; - correction d’erreurs dans les références aux articles, paragraphes, figures et procédures, ainsi que dans la bibliographie; - alignement des termes et définitions en 3.1 sur ceux de l’IEC 61281-1.
