1. A system comprising:
a controller configured to:
determine a first amount of current associated with a first power level,
generate a digital pulse signal based on the first amount of current, the digital pulse signal having a second power level and an associated duty cycle, the second power level being selected by the controller based on a digital value being associated with the second power level, and the duty cycle being selected by the controller based on a difference between the second power level and the first power level,
convert the digital pulse signal, using the digital value, into a second amount of current, andoutput the second amount of current as a pulse signal based on the duty cycle; an optical pump configured to:
receive the second amount of current from the controller, andgenerate optical power, associated with the first power level, based on the second amount of current and the duty cycle; and an amplifier module configured to:
receive an optical signal,receive the optical power from the optical pump,add gain, using the optical power, to the optical signal, and output the optical signal after adding the gain, where the duty cycle is a first duty cycle, and where the controller is further configured to:
receive feedback information;determine, based on the feedback information, that the optical pump requires a third amount of current associated with a third power level;generate a second digital pulse signal based on the feedback information, the second digital pulse signal having a fourth power level and an associated second duty cycle, the fourth power level being different than the third power level and the second duty cycle being different than the first duty cycle;convert the second digital pulse signal into a fourth amount of current; andoutput the fourth amount of current as a pulse signal based on the second duty cycle. |
