POS-202

Polarization Stabilizer

The POS-202 Polarization Stabilizer maintains stable output states of polarization (SOP) against input SOP fluctuations.

Product Description

The POS-202 architecture includes a fiber squeezer polarization controller, in-line polarization monitor, and proprietary algorithms. They are able to compensate for an input polarization discontinuity in as fast as 5 ms, or track without resets against a continuous input SOP rotation of up to 32π/s.

The POS-202 is a simple instrument that stabilizes the output SOP to linear, aligned to the slow axis of its output PM fiber.
