L-band Erbium-doped Fiber Small Signal Amplifier
Design Tools
The L-band erbium-doped fiber small signal amplifier (PA amplifier for short) is an amplifier dedicated to L-band weak optical signals in the range of-45dBm to-25dBm. The typical gain of small signals is as high as 45dB and has a low noise figure. It is usually used before photodetectors to improve their ability to detect weak optical signals.
