Product introduction
The KY-EDFA-BA series BA-EDFA is a fiber amplifier specially used for single-wavelength or multi-wavelength. It is usually placed at the back end of the optical transmitter to increase the optical power of the transmitted signal. This product adopts high erbium-doped fiber and purely analog pump laser drive circuit to ensure its high gain and low noise. It can display input and output optical power,pump laser working current, working temperature , cooling current and other parameters in real time. This product is mainly used in long-distance optical fiber communication system, quantum communication, picosecond pulse amplification, optical fiber sensing systems and other fields.
