Product introduction

The KY-EDFA-PA series Pre-EDFA is a fiber amplifier specially used for small signal amplification. It is usually placed at the front of optical receiver or photodetector to increase the sensitivity of photodetector. This product is a two-stage amplification structure. It adopts low-noise 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 high-speed optical fiber communication system, quantum communication, picosecond pulse amplification, optical fiber sensing systems and other fields.
