ABSTRACT:
The present invention concerns a generator (G1) for generating at least M data carrier optical signals with selectable carrier wavelengths, where M is an integer greater than 1, said generator comprising N laser sources (Si) with constant and different wavelengths, where N is an integer greater than 1, and an optoelectronic modulator (Mod1) adapted to form one of said M optical data carrier signals,which generator is characterized in that it includes:M−1 other optoelectronic modulators (Mod2to ModM) each adapted to form one of said M−1 other optical data carrier signals, andan at least partially broadcasting optical switch (100) having N input ports (PEi) connected to the N laser sources and M output ports (PSi) connected to the M modulators, the optical switch being adapted to send to a plurality of modulators an output signal with a selectable carrier wavelength, to form said M signals.
