L-Band 35dB Gain Faxtor PA EDFA SM Fiber Amplifier Desktop Type EDFA-L-PA-35-SM-B1
The L-band erbium-doped fiber small-signal amplifier (PA amplifier) is specifically designed for amplifying weak optical signals with an input power range of -45 dBm to -25 dBm. This amplifier typically achieves a small-signal gain of 45 dB and features excellent low noise figure characteristics, effectively improving the system's detection sensitivity and response to weak optical signals. It is widely applicable to applications such as optical communication and fiber optic sensing where weak signal requirements are stringent.

*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.
