Abstract

A system for sending data in an optical network comprising a plurality of source nodes and destination nodes is disclosed. In one aspect, a source node generates, in a spectral band that is associated with it, a multi-carrier optical data signal obtained by modulation of a source signal at a source wavelength and sends it in the form of single-band data bursts that can be associated with distinct source wavelengths. A single-band data burst comprises, in addition to payload data symbols (PL), a sequence of learning symbols (TS) composed of a plurality of learning symbols. A control unit belonging to the control plane of the optical network determines, for at least one of the source nodes, instants of sending of the single-band data bursts and source wavelengths to be used for sending these single-band data bursts, as a function of a path time of the data bursts between the source node and one of the destination nodes associated with the source wavelength. The control unit also determines the size of the sequence of learning symbols (TS) of the single-band data bursts.
