    • The invention relates to a method for receiving an optical signal including a step for coherently detecting said optical signal, outputting a multicarrier signal received, and a step of processing said received multicarrier signal, which includes a step of estimating a frequency offset affecting the received multicarrier signal relative to a corresponding multicarrier transmitter signal. According to the invention, the estimation step (21) implements two sub-steps including: a sub-step (211) of determining the entire portion of the frequency offset; a sub-step (212) of determining the fractional portion of the frequency offset; the sub-step of determining the entire portion implementing a measurement, in the spectral range, of an offset between the position of at least one specific carrier of the multicarrier transmitter signal and the position of the corresponding specific carrier or carriers in the received multicarrier signal.

    • The invention relates to a system for emitting data in an optical network comprising source nodes (1-1, 1-2, 1-3, 1-4, 1-5), which are able to each generate, in a spectral band associated therewith, a multi-carrier optical data signal obtained by modulating a source signal at a source wavelength, and to emit this signal in the form of mono-band data bursts (11-13, 21-23, 31-33, 41-43, 51-53) that can be associated with distinct source wavelengths, and a combiner (1, 2) of the mono-band bursts, emitted by the source nodes in the spectral bands associated therewith, into multi-band bursts (61-63, 71-73), occupying a spectral band corresponding to a juxtaposition of the spectral bands associated with the source nodes. In this system, a unit for controlling an instant of emission of the mono-band bursts by the source nodes implements a control plan which takes account of a journey time of the mono-band bursts emitted by the source nodes to the combiner.
