Fibre optic communication subsystem test procedures - Part 2-2: Digital systems - Optical eye pattern, waveform and extinction ratio measurement
IEC 61280-2-2:2012 describes a test procedure to verify compliance with a predetermined waveform mask and to measure the eye pattern and waveform parameters such as rise time, fall time, modulation amplitude and extinction ratio. This fourth edition cancels and replaces the third edition published in 2008 and constitutes a technical revision .This edition includes the following significant technical changes with respect to the previous edition: additional definitions; clarification of test procedures. Keywords: optical eye pattern, waveform, modulation amplitude, extinction ratio The contents of the corrigendum of February 2015 have been included in this copy.
Procédures d’essai des sous-systèmes de télécommunication fibroniques - Partie 2-2: Systèmes numériques - Mesure du diagramme de l’œil optique, de la forme d’onde et du taux d’extinction
IEC 61280-2-2:2012 décrit une procédure d’essai pour vérifier la conformité à un masque de forme d’onde prédéterminé et mesurer le diagramme de l’œil et les paramètres de la forme d’onde tels que le temps de montée, le temps de descente, l'amplitude de modulation et le taux d’extinction. Cette quatrième édition annule et remplace la troisième édition parue en 2008 et constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: définitions supplémentaires; clarification des procédures d'essai.
La présente version bilingue (2020-09) correspond à la version anglaise monolingue publiée en 2012-10.
