Abstract

Cette invention se rapporte à un procédé et à un appareil de traitement de signaux optiques, qui servent à combiner les lignes d'insertion/extraction de plusieurs multiplexeurs d'insertion/extraction (ADM) (58, 60,62) en une seule paire de lignes d'insertion/extraction (54, 56), ce procédé et cet appareil utilisant plusieurs lignes réseau à fibres optiques (42, 44, 46, 48, 50, 52) pour assurer le traffic interurbain, plusieurs unités de dérivation (58, 60, 62) reliées chacune à l'une des lignes réseau à fibres optiques et comportant chacune un port d'insertion et d'extraction, un réseau de fibres (472) prévu dans chaque unité de dérivation et servant à transférer le traffic interurbain du port d'insertion au port d'extraction de chacune des unités de dérivation, et une seule paire de fibres connectant les unités de dérivation pour assurer le traffic de dérivation entre les unités de dérivation.
