PDLM1000 Polarization Dependent Loss Multimeter

Key features

  • Like EPS1000 polarization scrambler with built-in photodetector(s), but polarization-dependent loss (PDL) is calculated in firmware, not externally.
  • PDL measurement interval <100 ms
  • PDL measurement range <0.05 dB ... >40 dB
  • Mean insertion loss is likewise determined.
  • For measurement principle and results see here.
  • For hardware setup(s) see here.
  • Polarization scrambler functionality is kept.
  • Fully programmable (USB, LAN, GUI, Matlab, Python, C, ...)
  • We are eager to accommodate special requirements.

Configuration


Standard configuration of PDLM1000. DUT = device under test. An optical switch can be built in, to make the polarization scrambler EPS1000 accessible without coupler insertion loss.
