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

High Power Erbium-doped Fiber Amplifier for L-band is based on the principle of stimulated amplification of optical signals in erbium-doped fibers. It adopts an efficient single-mode fiber optical amplification design and 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 fiber communication systems, fiber sensors, laser lidar, etc.

Features

  • High output power
  • High Gain
  • Wide wavelength range

Applications

  • Fiber Communications
  • Fiber Laser
  • Fiber Sensors

*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 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
