Product introduction

The KY-APRM-BW-I-2 series dual-channel avalanche photoreceiver uses imported avalanche photodiodes with high gain, fast response and low dark current. It integrates low noise broadband transimpedance amplifier TIA, boost and temperature compensation circuit,with high gain and high sensitivity. The module is powered by positive 12V,and the fiber interface is universal for single-mode and multi-mode optical fiber. The electric signal is SMA output, which is suitable for weak light signal detection and short pulse signal measurement. It’s mainly used in raman temperature measurement,fiber vibration monitoring systems and other fields.
