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.

Abstract: A coherent optical receiver capable of receiving a multiple-wavelength optical signal comprising a series of single-band optical bursts is described. Each single-band optical burst is carried by one wavelength from among a plurality of wavelengths on a predetermined spectral band. The optical receiver can include optical generation means arranged to generate a local multiple-wavelength optical oscillator consisting of a plurality of optical lines at wavelengths corresponding to the wavelengths of the optical bursts, optical mixing means arranged to mix the optical oscillator and the optical signal in order to generate at least one mixed optical signal comprising a plurality of beats between at least one of the single-band optical bursts and the optical lines of the local multiple-wavelength optical oscillator, and a detection means to filter at least one beat between said single-band optical burst and one of the optical lines of the local multiple-wavelength optical oscillator.
