There are 2 types of EDFA, the module type and the desktop type. The module type of C-band EDFA with PM fiber. It include a RS232 interface and control by the command. It needs a DC 5V adapter as the power supply. The desktop type erbium-doped fiber amplifier is controlled with buttons or software. It’s working voltage is AC 100V~220V. Let’s check it now.
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.
