It’s a 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, laser radar, etc.
