Abstract:
    A device (D) is dedicated to optical switching in a switching node (NC) of a transparent optical network. This device (D) comprises i) at least one input port adapted to be coupled to an upstream optical line (FE1-FE4) dedicated to the transport of multiplexed channels, ii) at least one exit point, iii) switching means (MC) coupling each input port at least to each exit point, and iv) processing means (MT1-MT4) adapted to add to the channels that reach each input port a signature including first information representative of that switching node (NC), and where applicable the input port that received them.
