DK Photonics Erbium-doped Fiber Pre-Amplifier for C-band (High-gain version) is a multi-level structure fiber amplifier product, and the pump power of each level can be independently controlled and operated. Users can independently adjust the pump current at each level to achieve the best amplification effect; And it is convenient to insert optical filters corresponding to the signal wavelength between the amplified optical paths, which can significantly improve and optimize the noise characteristics of the fiber amplifier, making it very suitable for scientific research experiments. Users can choose this function on the basis of standard product models or customize it according to their requirements.

*Note 2: ACC mode: Auto 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: Auto power control mode, where the user sets the signal light output power of the fiber amplifier. The fiber amplifier automatically controls and adjusts the pump current based on the output power monitored by the PD 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, the amplifier will minimize the fluctuation of output power as much as possible.
