L-Band Erbium-Doped Fiber Pre-Amplifier Module Type 35dB Small Signal Gain EDFA-L-PA-35-SM-M

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 ~ -25 dBm. The typical small signal gain is up to 45 dB, and it also has a low noise index. It is usually used in front of a photodetector to improve its ability to detect weak light signals.

*Note1

 

*Note1:
ACC mode - automatic current control: The EDFA pumping operating current is set by the user and automatically locked by the EDFA to achieve a constant pumping current. When the input optical power fluctuates, the output power will also fluctuate accordingly, which is suitable for all EDFA models.
