ADVA Optical Networking EDFA-C-D20-VLGC-DM Optical Amplifier is a double-stage erbium-doped fiber amplifier designed for C-band DWDM networks, delivering up to 20 dBm of output power. The DM variant features dual monitoring ports for inline supervision, and the VLGC designation indicates variable-gain control within the C-band on a G.652 fiber link. Identified by part number 1063709052, this EDFA module is used as an amplification element in ADVA's DWDM installations, typically deployed where higher gain and robust signal integrity are required across a C-band path.
