Patent

CA 2444360

An encoding/decoding device for OCDMA communications with an optical network is provided. The device uses a single reflecting element to perform both the encoding of outgoing signal and the decoding of incoming signal. A directional optical assembly allows to differentiate the origin of the signals to forward the outgoing signals after encoding to the network and the incoming signals after decoding to a receiver.

La présente invention concerne un dispositif de codage/décodage pour des communications à accès multiple par code optique de répartition avec un réseau optique. Le dispositif utilise un unique élément à pouvoir réfléchissant pour effectuer à la fois le codage du signal de sortie et le décodage du signal entrant. Un ensemble directionnel optique permet de distinguer l'origine des signaux pour acheminer les signaux de sortie après codage vers le réseau et les signaux entrants après décodage vers un récepteur.
