L'IEC 63110-1:2022, qui sert de base aux autres parties de l'IEC 63110, couvre les définitions, cas d'utilisation et architectures pour la gestion des infrastructures de charge et de décharge des véhicules électriques.
Elle porte sur les exigences générales relatives à la mise en place d'un écosystème de mobilité électrique et couvre donc les flux de communication entre les…
Fibre optic communication subsystem test procedures - Part 4-3: Installed passive optical networks -...
IEC 61280-4-3: 2022 describes the measurement of attenuation, optical return loss and optical power in installed passive optical networks (PONs) using single-mode fibre. This document specifies two methods for measuring the attenuation before activation of the PON:
method A: one-cord method using a light source and a power meter (LSPM);
method B: optical time-domain reflectometer (OTDR)…
