The POD-201 is an in-line fiber-coupled polarimeter that simultaneously measures the four Stokes parameters to yield the instantaneous state of polarization (SOP) and degree of polarization (DOP) of input light.
The POD-201 in-line polarimeter enables real time monitoring of the SOP, DOP, and power of a light signal in fiber. It also has averaging and statistical functions to measure the time-averaged DOP of a polarization scrambler, to track SOP variation from a reference value, and to monitor the maximum and minimum values of various parameters within a given measurement period.
The PolaView data display and analysis software displays SOP information either on a Poincaré sphere display or on a virtual oscilloscope. It also has functions for PER measurement and for streaming SOP vs. time information to a data file.
- User calibration function to optimize DOP and SOP accuracies at arbitrary wavelengths and temperatures
- Real time Poincaré Sphere display, analog voltage output for SOP/DOP/power for ATE integration
- Data logging of SOP up to 1 billion points
- Averaged DOP measurement function for scrambled-input measurement
