High-Power Polarization Maintaining EDFA for L-band

DK Photonics High-Power Polarization Maintaining EDFA for L-band is based on the principle of laser amplification of optical signals in erbium-doped fibers. It adopts efficient polarization maintaining fiber optical amplification design and high-power laser heat dissipation technology to achieve high-power polarization maintaining output of 1570-1605nm wavelength lasers. It has the advantages of high power, high extinction ratio, and low noise, and can be used in fiber optic communication, laser radar, etc.

*Note 1:

  1. ACC mode: Automatic current control mode, where the user sets the pump working current of the fiber amplifier and the fiber amplifier automatically locks it to achieve a constant pump current. When the input optical power fluctuates, the output power will also experience corresponding fluctuations.
  2. 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.
  3. AGC mode: Automatic gain control mode, where the user sets the gain coefficient of the fiber amplifier. The amplifier automatically adjusts the pump current based on the input and output power detected by the PD to achieve the most stable gain multiple. When the input optical power fluctuates, the output power will also fluctuate accordingly, but the gain coefficient is generally stable. 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.
