C-Band 20dBm Gain Flattened Erbium-doped In-Line Amplifier Benchtop EDFA-C-LA-GF-20-SM-B
Erbium-doped optical fiber line amplifier (LA amplifier for short) is an optical power amplifier product specially used for line relay in fiber laser or optical fiber communication systems. It combines the advantages of PA amplifier and BA amplifier and can provide high gain for small signals and has a relatively high performance. High output power; has the advantages of high gain, high transmit power, and low noise. It is used between fiber segments to increase the relay length or in the corresponding single-point to multi-point portion of the optical access network to compensate for branch losses.
The gain flat erbium-doped fiber amplifier is a series of fiber amplifiers specially designed for optical fiber communication systems. It can simultaneously amplify multiple wavelength signals in the C-band, and maintain the same gain between wavelengths, with a gain flatness of ≤1.5 dB. It has the advantages of wide spectrum, multiple wavelengths, flat gain, high gain and low noise.

*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.
