Product introduction
The KY-EDFA-PL series pulse EDFA is a fiber amplifier specially used for pulsed optical signal amplification. It can amplify optical pulses with a frequency of 1Hz-1MHz and a pulse width of less than 100ns,the maximum output peak power can reach 500W. This product adopts low-noise erbium-doped fiber and purely analog pump laser drive circuit to ensure its high gain and low noise figure. 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 optical fiber communication system, quantum communication systems, picosecond pulse amplification, laser radar, optical fiber sensing systems such as Raman, Brillouin and φ-OTDR,and other fields.
