High Power Single-Mode Erbium-doped Fiber Amplifier for L-band

The L-band high-power erbium-doped fiber amplifier is based on the principle of laser amplification of optical signals in the erbium-doped fiber. It uses a unique multi-stage optical amplification design and reliable high-power laser heat dissipation technology to achieve high-power output of 1570~1605nm wavelength lasers. It has the advantages of high power and low noise, and can be used in optical fiber communication systems, optical fiber sensing, laser radar, etc.

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: 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.
