Abstract

Pour compenser la dispersion optique survenant dans un système optique à transmission bidirectionnelle, des dispositifs optiques (par exemple, module d'amplification (10)) sont prévus qui comportent un seul module de compensation de dispersion chromatique, à transmission bidirectionnelle, agissant sur les signaux se propageant dans les deux sens de transmission. La transmission bidirectionnelle sur chaque tronçon de ligne s'effectue au moyen de paires de fibres optiques à transmission unidirectionnelle. Des circulateurs optiques indépendants de la polarisation (C1, C2) permettent l'aiguillage approprié des signaux optiques. Le module de compensation peut compenser la demi-somme des dispersions chromatique des deux tronçons de ligne qui relient un module d'amplification (10) aux sites d'amplification voisins, ou bien une partie des dispersions chromatique (afin de sous-compenser des tronçons longs et de sur-compenser des tronçons longs). Un multiplexeur d'insertion/extraction comportant deux modules d'insertion/extraction de signaux optiques comporte aussi deux éléments de compensation de dispersion chromatique, à transmission bidirectionnelle, chacun étant disposé entre un tronçon de ligne respectif et les deux modules d'insertion/extraction.
