Product Info


Introduction

The APD modules are based on low-noise avalanche photodiodes made of InGaAs with a built-in pre-amplifier and high voltage supply.A temperature compensation function allows the APD to be operated at constant gain across a wide operating temperature range.

1. Overview

APD-DTS is a dual avalanche photodetector for distributed fiber optic temperature measurement. It is internally based on low noise amplifiers, boost circuits, and temperature compensation circuits, featuring high gain and fast response. The module is powered by a single power supply for easy integration, and the outputs use SMA connectors to reduce size and maximize frequency response, with a maximum bandwidth of 200MHz.


2. Features

  • Covering wavelength range 1000-1700nm
  • DTS-specific, dual-channel
  • M-factor temperature compensation
  • Connects to singlemode (SM) or multimode (MM) fibers
  • FC fiber input header
  • Supports customization


3. Applications

  • Distributed Fiber Optic Temperature
  • Measurement System DTS
  • OTDR
