In cases where it is necessary to consider the influence of polarization dependency in high-speed optical communication (measurement of 100 G proof stress) and various experiments,
the consideration process has been time-consuming until now because various polarized optical devices have to be set up to output arbitrary polarization states.
This product can generate arbitrary PDL with high precision and high resolution for inputted linearly polarized light, and then output the light.


– Low insertion loss
– PDL generation resolution: 0.1 dB
– Max. PDL generation: 10 dB
– Manual operation capability and external control capability by USB
