The present invention relates to a method and a device for crosstalk reduction in a communication link for simultaneous and bidirectional optical transmission. In order to reduce crosstalk, two different optical wavelengths and two different electrical carrier frequencies are utilised. Applications of interest include optically based subscriber access systems and systems for optical interconnections in various information processing systems, such as computers.
L'invention concerne un procédé et un dispositif servant à limiter la diaphonie dans une liaison de communication servant à effectuer une transmission optique simultanée et bidirectionnelle. On utilise deux longueurs d'ondes optiques différentes et deux fréquences porteuses électriques différentes afin de limiter la diaphonie. Cette invention peut être mise en application avantageusement dans des systèmes d'accès d'abonné à base optique et dans des systèmes d'interconnexion optique dans différents dispositifs de traitement d'information, tels que des ordinateurs.
