The erbium-doped fiber small signal amplifier (PA, Pre-Amplifier) is dedicated to the amplification of weak optical signals in the range of -45dBm ~ -25 dBm. The typical gain of small signal is as high as 35 or 45 dB, and it has a low noise figure. Used before the photodetector to improve its ability to detect weak light signals.
