*Note 1:

  1. ACC mode: Automatic current control: the EDFA pump working current is set by the user and automatically locked by the EDFA to achieve a constant pump 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 mode, where the user sets the signal light output power of the EDFA. Based on the output power monitored by the PD, the EDFA automatically controls and adjusts the pump current to achieve stable output signal. In APC mode, the user can adjust the output power within a range of 10% to 100% of the maximum output power. The advantage of APC mode is that when the input optical power fluctuates, EDFA will minimize the fluctuation of output power as much as possible
