PDLE-101 PDL Source/Emulator

The PDLE-101 is a polarization dependent loss (PDL) source that generates PDL values up to 20 dB.

The PDLE-101 differentially attenuates one polarization component of input light to create a variable amount of PDL. It can generate PDL values up to 20 dB with a resolution of 0.1 dB for PDL tolerance testing. It can also generate variable PDL patterns with user defined range, waveform, and speed for PDL tracking speed and recovery time tests.

Key Features

  • Large PDL range: 20 dB
