Gain 25dB EDFA Erbium-doped Fiber Amplifier Pre Amplifier Multi-wavelength Advanced LCD type
Multi-wavelength Gain Flatness Erbium doped fiber amplifier (GFF EDFA ) is a family of fiber amplifier products dedicated to optical fiber communication systems，it has multi wavelength and gain flattening， and high gain and low noise advantages, support PC software control, compact, easy to integrate, but also according to customer needs to provide desktop or rack type packaging.
There are two types EDFA.(Current product is Pre-Amplifier type.)
Pre - Amplifier, referred to as PA, that is preamplifier, used in the -40 ~ -25 dBm range of small light signal amplification, typical gain of 35 dB;
Booster - Amplifier, referred to as BA, is used to enhance the power of the optical signal in the range of - 6 ~ + 3 dBm, with a maximum output power of 27 dBm;
[Characteristic]
Wide working wavelength range;
High gain and flat gain;
Good temperature adaptability.
[Application]
Optical fiber communication
optical fiber sensor

*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.
APC mode - automatic power control: The signal light output power of the EDFA is set by the user, the PD automatically monitors and feeds back the output power, the EDFA control and the adaptive adjustment pump achieve the stability of the output signal. When the input optical power fluctuates, the APC mode minimizes the fluctuation of the output power and is suitable for power type and line type EDFA.
