 The one in the video is a benchtop 40dBm erbium-doped fiber amplifier. The input and output fibers of the PM amplifier are polarization maintaining fiber PM1550 and the connector keys are aligned the slow axis. This EDFA is designed to amplify optical signals up to 10W average power for high power applications at 1550nm wavelength range. The operating current or output power can be adjusted by pressing the button. You can choose the software control function and use the RS232 interface to connect to the software. The two working modes of ACC and APC can be switched. In APC mode, the output power can be adjusted. In ACC mode, the operating current can be adjusted. The high-power polarization-maintaining erbium-doped fiber amplifier is based on the polarization-maintaining double-clad erbium-doped fiber amplification technology. It adopts a unique fiber packaging process and a reliable high-power laser protection design to achieve high-power laser polarization-maintaining output i...

 It's a 40dBm erbium-doped fiber amplifier . The working status of this EDFA is controlled by buttons. This is a very high power fiber amplifier with 3 cooling fans inside. This EDFA is configured with single-mode fiber. The left and right buttons switch between ACC/APC two control modes. ACC automatic current control, the current setting range is 0~9600mA. APC automatic power control, the power setting range is 23~33dBm.The up and down buttons are to adjust the current/power. The middle button is the confirmation key. Let's check it now. High-power single-mode erbium-doped fiber amplifier (EYDFA-HP) is based on the principle of laser amplification of optical signals in erbium-doped fiber, using unique multi-stage optical amplification design and reliable high-power laser heat dissipation technology to achieve the wavelength range of 1540~1565nm Internal high-power laser output. It has the advantages of high power and low noise, and can be used for optical fiber communication,...
