POD – Polarimeter
DESCRIPTION
The POD module is an in-line polarimeter for low cost, high-speed polarization characterization without interrupting data traffic. It outputs four voltage signals for calculating both the degree of polarization (DOP) and the state of polarization (SOP) of the light passing through the device. It comes with a preamplification board to provide analog signals for SOP/DOP calculation, feedback control, and computer interface. A calibration matrix is provided with every device for the calculation. Devices without preamplification board and calibration matrix are also available for OEM applications.
FEATURES
High speed and low loss
Compact size
No moving parts
APPLICATIONS
Integration into polarization monitoring and polarization stabilization systems
Integration with polarization characterization systems
