Product introduction

The KY-QRA series raman fiber amplifier uses imported high-performance and high-power 1480nm pump lasers, which can achieve 1W continuous output by polarization combining. The purely analog pump laser drive circuit guarantees the high gain and low noise figure of the amplifier.The desktop machine can display the input and output optical power, pump laser operating current, working temperature, cooling current and other parameters in real time.This product is mainly used in long-distance optical fiber communication systems, optical fiber sensing systems, scientific research and other fields.
