ABSTRACT:
The digital information transmitting system comprises several subscriber stations and a processor for managing the exchange of information between said stations. The processor includes several optical circuits for receiving information emitted from the optical emitters in the stations respectively, and a single optical circuit for emitting grouped informations to all the optical receivers of the stations. An optical transmission pluribus is interconnected between the stations and the processor. The optical pluribus comprises several optical unidirectional forward lines for each linking the respective station emitter to a respective receiving circuit of the processor, and a single optical unidirectional distributed backward line for linking the single emitting circuit of the processor to all the station receivers.
