40dBm 10W High Power Erbium-doped PM Fiber Amplifier

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. It supports two working modes: ACC and APC. 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 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.

2023 New PM Erbium-doped Fiber Amplifier

This is a C-Band Erbium Doped Fiber Amplifier, high gain and low noise. It is the latest style of 2023, with a silver shell. The heat sink of the fiber amplifier is upward. This is Polarization-Maintaining Erbium-Doped Fiber Amplifier, SM Fiber EDFA can also be customized.

Polarization-maintaining erbium-doped fiber amplifier (EDFA-PM) is a family of fiber amplifier products dedicated to polarization-maintaining fiber systems. It has the advantages of high gain, low noise, and polarization retention. It supports host computer software control. Need to provide bench-top or rack-mount package, accept parameter customization.
