High Power Erbium-doped Fiber Amplifier Module in Compact Size for C-band

DK Photonics High Power Erbium-doped Fiber Amplifier Module in Compact Size for C-band is based on the principle of laser amplification of optical signals in erbium ytterbium co doped fibers. It adopts a uniquely designed optical path structure and reliable high-power laser heat dissipation technology. The working wavelength range covers 1535-1565nm, and the output optical power is 0.5-2W, with the advantages of high power and low noise. The compact module design facilitates system integration and can be used for fiber optic sensing, fiber optic communication, laser radar, and more.

*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
  3. AGC mode: Automatic gain control mode, in which the user sets the gain coefficient of EDFA. EDFA will automatically control and adjust the pump current based on the input and output power detected by 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.
