Abstract

La présente invention concerne un procédé et un dispositif pour déterminer le type d'une ONU, d'une OLT, et un support de stockage. Le procédé consiste à : recevoir des données envoyées par une unité de réseau optique (ONU) désignée, et déterminer un canal de transmission de données pour transmettre les données ; déterminer, d'après la corrélation entre le canal de transmission de données et le type d'ONU, le type d'ONU correspondant au canal de transmission de données, et utiliser le type d'ONU déterminé en tant que le type de l'ONU désignée. La présente invention résout le problème lié, dans l'état de la technique, aux opérations complexes concernant la coexistence du réseau optique passif, en réduisant la complexité des opérations.
