ABSTRACT:
A process for optical transmission by self-heterodyning and a transmission system with a switching matrix using the process. The process consists in transmitting optical signals to one or more receivers of N, from optical transmission means including an optical signal emitting device for modulation by frequency transposition, and an optical fiber connection. Also included in the process is the transmission a given signal on one or more carrier frequencies respectively to one or more receivers, the obtaining of the carrier frequency or frequencies by transposition of an emission frequency by one or more modulation frequencies which are distinct and can be selected as a function of the receiver or receivers, and the transmission of the emission frequency signal on the same optical connection.
