Title (EN) AWG BASED OADM WITH IMPROVED CROSSTALK
(FR) MULTIPLEXEURS OADM A RESEAUX AWG A CARACTERISTIQUE DE DIAPHONIE AMELIOREE
Abstract: front page image
(EN)An optical add/drop multiplexer 'OADM' (14) system with reduced crosstalk, and a method to reduce the system crosstalk in an OADM system are provided. The reduction of system crosstalk is achieved by the replacement of at least one of the common wavelength-independent switches in the drop switch (12) or switch array (12), with at least one wavelength-dependent switch.
(FR)L'invention concerne d'une part un système à multiplexeur d'insertion/extraction optique « OADM » (14) réduisant la diaphonie, et d'autre part un procédé de réduction de la diaphonie de système dans un système OADM. On réduit la diaphonie de système en remplaçant au moins l'un des commutateurs communs indépendants des longueurs d'ondes, dans le commutateur d'extraction (12) ou le réseau de commutateurs (12), par au moins un commutateur dépendant des longueurs d'ondes.
