*Note 1:

ACC mode - automatic current control: the user sets the EDFA pump operating current, and the EDFA automatically locks it to achieve constant pump current. When the input optical power fluctuates, the output power will also fluctuate accordingly. It is applicable to all EDFA models. PA amplifiers only support ACC mode.

APC mode - automatic power control: the user sets the EDFA signal light output power, the PD automatically monitors and feedbacks the output power, and the EDFA controls and adaptively adjusts the pump to achieve output signal stability. The power adjustment range in APC mode is usually 10%~100%. The advantage of APC mode is that when the input optical power fluctuates, the EDFA will reduce the output power fluctuation as much as possible. It is applicable to power-type and line-type EDFA, but not suitable for low repetition frequency pulse signals.
