EDFA is an erbium-doped fiber amplification card launched by Shenzhen JHA Technology Co. ,Ltd. Its main function is to compensate the power of the signal light in the transmission link, and it can amplify the optical signals of up to 48 channels (channel interval of 100 GHZ) or 96 channels (channel interval of 50 GHZ) at C band at the same time. It has characters of flat gain, locked gain, low noise figure, etc. and it’s an indispensable important component for DWDM system, future high speed system and all-optical network long-distance transmission.
