Optical node () comprising at least one input port (PA, PC, PE) and a plurality of output ports (PB, PD, PF), at least one add unit (B,D,F) for adding at least one signal on an output port (PB, PD, PF), a broadcasting unit () for broadcasting on at least two output ports (PB, PD, PF) the express traffic received on an input port (PA, PC, PE), characterized in that the broadcasting unit () is configured for broadcasting at least one added signal on at least two output ports (PB, PD, PF).

Flexible node architecture with full protection

In order to determine a spectral route between a departure node (N) and an arrival node (N) in a WDM optical telecommunications network, the method comprises a step of determining a spatial route connecting the departure node to the arrival node, said spatial route comprising a sequence of route segments (Li), each route segment directly interconnecting two network nodes and being capable of conveying at least one wavelength. The method further comprises the following steps:
