Abstract
An optical system includes an optical transmitter and a controller that determines a particular wavelength for a channel of the optical transmitter. The controller causes the optical transmitter to transmit a first optical signal with a first data sequence that is determined based on the particular wavelength, and determines a first optical power that is generated based on the first optical signal and the first data sequence. The controller causes the optical transmitter to transmit a second optical signal with a second data sequence that is determined based on the particular wavelength, and determines a second optical power that is generated based on the second optical signal and the second data sequence. The controller calculates a power difference between the first optical power and the second optical power, and causes the particular wavelength for the channel to be modified based on the calculated power difference.
