Section outline

  • In this video, Benjamin Koch introduces the fundamental concepts and methods used to measure and analyze State of Polarization (SoP) changes in optical fibers, with a focus on practical application using the Novoptel PM1000 polarimeter.

    Watch this video to understand how to:
    • visually represent polarization;
    • recognize  environmental impacts on fiber polarization;
    • accurately measure and analyze these effects with tools like the PM1000;
    • ensure reliable data processing through timestamp correction, advanced recording techniques, and research software, as MATLAB.
