Product Info

Introduction

The PD12 is a photodetector with amplification circuitry for use with FC-connected fiber optic cables in optical systems. The device consists of a photodiode, transimpedance amplifier, and RF connector packaged in an aluminum housing.

1. Overview

The PD12 is a photodetector with amplification circuitry for use with FC-connected fiber optic cables in optical systems. The device consists of a photodiode, transimpedance amplifier, and RF connector packaged in an aluminum housing.The FC flange facilitates coupling to a fiber optic light source, and an SMA connector is used at the output to reduce size and maximize frequency response up to a maximum bandwidth of 1 GHz.The detector is available in two spectral ranges, 400-1000 nm and 1000-1700 nm.


2. Features

  • Covers wavelength range of 400-1700nm
  • Bandwidth from kHz to GHz
  • Connects to singlemode (SM) or multimode (MM) fibers
  • FC fiber input header
  • Supports 4/8/16 channel customization


3. Applications

  • Detection of weak light signals
  • Detection of fast laser pulses
  • Detection of aberrant laser beat signals
