Abstract:
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.
