Estimating the term…
A method for controlling an optical amplifier is disclosed. The illustrative method includes inputting a set-point to a controller; receiving a portion of an input signal; receiving a portion of an output signal from a first amplifier stage; receiving a portion of an output signal from an attenuation stage; receiving a portion of an output signal from a second amplifier stage and adjusting the first amplifier stage, the second amplifier stage and the attenuation stage based on the received portions to substantially maintain the set-point. An optical amplifier includes a controller which receives a portion of an input signal, a portion of an output signal from a first amplifier stage, a portion of an output signal from an attenuations stage, and a portion of an output signal from a second amplifier stage. The controller adjusts the first amplifier stage, the attenuation stage, and the second amplifier stage based on the received portions of the signals.
A method for controlling an optical amplifier, the method comprising:
An optical amplifier, comprising:
33 An optical amplifier as recited in claim 32, wherein said first subcontroller adjusts said first amplifier stage based on commands from said second subcontroller.
34 An optical amplifier as recited in claim 23, further comprising a gain flattening filter disposed between said attenuation stage and said second amplifier stage.
