Title (EN) SPATIAL DIVISION MULTIPLEXED OPTICAL COMMUNICATION SYSTEMS AND AMPLIFIERS FOR THE SAME
(FR) SYSTÈMES DE COMMUNICATION OPTIQUE MULTIPLEXÉS PAR RÉPARTITION SPATIALE ET AMPLIFICATEURS ASSOCIÉS
Abstract: front page image
(EN)In optical amplifier assembly [308-1..308-n] for a spatial division multiplexing (SDM) optical communication system [300], each optical amplifier assembly [308-1..308-n] includes a single pump assembly [318-1..318N] configured for causing amplification of signals traveling on separate fiber paths [310e, 310w] in different directions. Each fiber path [310e, 310w] includes a plurality of spatial dimensions. The single pump assembly [318- 1..318N] includes a plurality of pump sources to provide redundancy and the optical amplifier assembly [308-1..308-n] further includes splitters [330a, 330b] for splitting outputs of the pump sources to amplifiers coupled to the different spatial dimensions.
(FR)Dans un ensemble d'amplificateurs optiques [308-1..308-n] destiné à un système [300] de communication optique avec multiplexage par répartition spatiale (SDM), chaque ensemble d'amplificateurs optiques [308-1..308-n] comprend un ensemble [318-1..318-N] de pompage unique configuré pour provoquer une amplification de signaux se propageant sur des chemins [310e, 310w] de fibres distincts dans des sens différents. Chaque chemin [310e, 310w] de fibre comprend une pluralité de dimensions spatiales. L'ensemble [318-1..318-N] de pompage unique comprend une pluralité de sources de pompage pour assurer une redondance et l'ensemble [308-1..308-n] d'amplificateurs optiques comprend en outre des diviseurs [330a, 330b] servant à diviser des sorties des sources de pompage vers des amplificateurs couplés aux différentes dimensions spatiales.
