Abstract: front page image
(EN)Improvements in or relating to Optical Networks The invention relates to improvements in or relating to optical networks, and methods and an apparatus for providing communications services. Receiving an optical signal is described comprising a carrier wavelength and optical data. The optical data is substantially erased, and the carrier wavelength is re-modulated with user data for onward transmission of the user data.
(FR)Cette invention concerne des améliorations apportées aux réseaux à fibres optiques ou concernant les réseaux à fibres optiques, ainsi que des procédés et un appareil permettant de fournir des services de télécommunications. Un signal optique comprenant une longueur d'onde porteuse et des données optiques est reçu. Les données optiques sont pratiquement effacées, et la longueur d'onde porteuse subit une remodulation avec les données d'utilisateur pour la retransmission desdites données d'utilisateur.
