Abstract
To solve a problem of modularity favoring under-equipping and a problem of energy losses in an all-optical distribution frame for optical lines, a primary converter block includes a redundancy circuit which can emit an optical signal with a wavelength different from any of the other wavelengths broadcast by the other converter circuits of the primary block. In this case a star coupler responsible for frequency domain cross-connection of the signals preferably includes P+1 input channels for P output channels.
