Product description

Fiber Optic Depolarizer - PolaZero™

This device is ideal for minimizing the polarization sensitivity of fiber optic sensor systems such as systems for quasi-distributed temperature and strain sensing based on fiber Bragg gratings (FBG), systems for distributed temperature and strain sensing based on Brillouin or Raman scattering, and systems for distributed acoustic sensing based on Rayleigh scattering.


  • For lasers with coherence length up to and beyond 10m
  • Low degree of polarization
  • Wide operating wavelength range
  • Low insertion loss
  • Compact size


  • Minimize polarization sensitivity of FBG based fiber sensor systems
  • Reduce polarization sensitivity of Brillouin, Raman, or Rayleigh scattering based distributed fiber sensor systems
  • Remove polarization sensitivity of Raman amplifiers
  • Eliminate polarization sensitivity of optical instruments
  • Reduce PDL effects of optical components
