Ytterbium-doped fiber amplifier (YDFA) generates gain by pumping ytterbium-doped fiber with a semiconductor laser to amplify laser signals in the 1030~1100nm band, Hi1060 single-mode fiber or PM980 polarization-maintaining fiber output, the output power is continuously adjustable, with high gain and low The advantages of noise. The desktop YDFA is convenient for experimental operation, and the user can adjust the pump current and output power through the buttons on the front panel. It also provides a more compact modular YDFA, which is convenient for users’ system integration. Both desktop YDFA and modular YDFA can support host computer software control and serial command control.

Note 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.
- APC mode-automatic power control: the user sets the signal light output power of the EDFA, PD automatically monitors and feeds back the output power, EDFA control and self-adaptive adjustment of the pump to achieve the stability of the output signal. The advantage of the APC mode is that when the input optical power fluctuates, the EDFA will reduce the output power fluctuation as much as possible, and it is suitable for power and line EDFAs.
