Introduction

Dual-channel APD photodetector module, 1000-1700nm, detecting Raman signals for DTS temperature measurement systems.

APD22 series is a dual-channel APD photodetector module with high gain, high sensitivity and low noise. The detector is integrated with a temperature sensor, and the bias voltage is precisely adjusted by MCU to compensate the effect of temperature change on M-factor; it can be used in DTS distributed Raman fiber temperature monitoring system.
