L-Band Erbium Doped 광섬유 증폭기 30mW~200mW EDFA Booster Amplifier LCD Desktop Type
L-band Erbium-doped 광섬유 증폭기 (EDFA) is a series of optical power amplifiers specially designed for optical fiber laser or optical fiber communication systems. Its working wavelength covers 1570-1603 nm. It has the advantages of high gain and low noise. It is compact and easy to integrate. It can provide desktop or module packaging.
There are two types EDFA.(Current product is Booster-Amplifier type.)
Pre amplifier: 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: 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;

*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.
