Methods and systems are described for communicating an optical data signal. An example method may comprise receiving data. The example method may comprise modulating the data to generate a modulated data signal. The modulated data signal may comprise a first level modulated with a first beacon tone and a second level modulated with a second beacon tone. The second level may be modulated in phase with the first level. The method may comprise transmitting an optical signal comprising the modulated data signal.

Methods and systems for multi-level beacon tone modulation of an optical data signal

Methods for systems are described for communicating an optical data signal. An example method may comprise receiving a data signal comprising a first level indicative of an upper end of a power range of the data signal and a second level indicative of a lower end of the power range of the data signal. The example method may comprise modulating the data signal to generate a modulated data signal. The modulated data signal may comprise the first level modulated with a first beacon tone and the second level modulated with a second beacon tone. The second level may be modulated in phase with the first level. The method may comprise transmitting an optical signal comprising the modulated data signal.
