(1) .ACC mode-automatic current control: EDFA pumping working current is set by the user and automatically locked by EDFA to achieve constant pumping current. When the input optical power fluctuates, the output power will also fluctuate accordingly, which is applicable to all EDFA models.

(2) APC mode-automatic power control: the user sets the EDFA signal light output power, PD automatically monitors and feeds back the output power, EDFA control and adaptive adjustment of the pump to stabilize the output signal. When the input optical power fluctuates, the APC mode will reduce the output power fluctuation as much as possible, which is suitable for power type and line type EDFA.
