POLARIZATION
MANAGEMENT MODULES

General Photonics’ in-line polarimeter is specially designed 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 in microseconds. PolaDetectTM is ideal for integration into polarization
monitoring and polarization stabilization modules, or in polarization characterization instruments.
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 purposes. The output fiber can either be single mode or PM fiber.
