Title:
CONTROL METHOD AND OPTICAL FIBER AMPLIFIER
Document Type and Number:
WIPO Patent Application WO/2021/047075
Kind Code:
A1
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 correcting a target gain on the basis of a first compensation gain to obtain an initially corrected target gain; when the actual power of the pump laser reaches a target power determined on the basis of the initially corrected target gain, obtaining, on the basis of a first signal optical power and a second signal optical power, a second compensation gain and a first compensation slope through calculation; correcting the initially corrected target gain again according to the second compensation gain to obtain a corrected target gain; and correcting a target slope according to the first compensation slope to obtain a corrected target slope. This solution can provide high precision control for the gain and the slope of the optical fiber amplifier.
