摘要： A method is provided for determining an optical signal to noise ratio of a dual polarization optical signal. The method includes: detecting, in the dual polarization optical signal, a modulation signal which modulates, at at least one low amplitude level that is approximately zero and at a high amplitude level, the dual polarization optical signal, and determining the optical signal to noise ratio from a measurement of the power of the modulation signal.

摘要： The invention relates to a system for sending data in an optical network comprising source nodes (1-1, 1-2, 1-3, 1-4, 1-5), each capable of generating, 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 of sending this signal in the form of single-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) for combining single-band data bursts, sent by the source nodes in the spectral bands that are associated with them, into multi-band data 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 sending of said single-band data bursts by the source nodes, implements a control plane taking account of a path time of the single-band data bursts sent by the source nodes to the combiner.

摘要： A method is provided for receiving an optical signal including a step of coherently detecting the optical signal, outputting a multicarrier signal received, and a step of processing the received multicarrier signal, which includes a step of estimating a frequency offset affecting the received multicarrier signal relative to a corresponding multicarrier transmitter signal. The estimation step implements two sub-steps including: a sub-step of determining the entire portion of the frequency offset; and a sub-step of determining the fractional portion of the frequency offset. The sub-step of determining the entire portion implements 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.

摘要： A method is provided for pre-distorting an optical signal, intended to be transmitted over an optical transmission line and including a plurality of frequency division multiplexed optical sub-carriers. The optical signal is obtained from an optical conversion of an electrical signal including a plurality of frequency division multiplexed sub-carriers. This method includes obtaining a plurality of corrective factors, corresponding to the electrical sub-carriers, as a function of a plurality of values, determined for the optical sub-carriers, of a first parameter dependent on the power of the sub-carriers, and application of the corrective factors to the amplitudes of the corresponding electrical sub-carriers, so as to equalize, at the output of the optical transmission line, the values of the first parameter for the sub-carriers of the optical signal.

摘要： A load-controlling device controlling load on an optical transmission line, the input of which is coupled to an emitting device for modulating with data and multiplexing a plurality of useful wavelengths into a useful optical signal to be transmitted over the transmission line. The load-controlling device includes elements for generating a filler optical signal composed of at least one filler wavelength that is not modulated by data, to be injected into the optical transmission line. The generating elements generate a source optical signal composed of a plurality of wavelengths corresponding to the plurality of wavelengths of the useful optical signal and selects the wavelength of the filler optical signal among the wavelengths of the source optical signal. A control module controls selection of the wavelength of the filler optical signal depending on information indicative of non-turn-on of a wavelength among the plurality of wavelengths of the useful optical signal.
