Abstract
Disclosed are a control method and an optical fiber amplifier. The optical fiber amplifier is configured to execute the control method. The method comprises: initially adjusting a target gain on the basis of a first offset gain to obtain the post-initial-adjustment target gain; when the actual power of the pump laser reaches target power determined on the basis of the post-initial-adjustment target gain, obtaining, on the basis of a first signal optical power and a second signal optical power, a second offset gain and a first offset slope through calculation; adjusting again the post-initial-adjustment target gain according to the second offset gain to obtain a adjusted target gain; and adjusting a target slope according to the first offset slope to obtain a adjusted target slope. This solution can provide high precision control for the gain and the slope of the optical fiber amplifier.
