The Newport 2560P fiber-optic Polarization Stabilizer offers fast response, low insertion loss, and reset-free polarization stabilization that can be used in coherent communications, fiberoptic sensors, fiber-optic interferometers, and all other applications that require a stable state of polarization (SOP). The polarization stabilizer integrates a dynamic polarization controller, an optical polarization detection circuit, and a microprocessor based electronic control circuit. It uses a proprietary polarization control algorithm that is capable of handling continuous slow polarization drift in one or more directions, such as polarization rotation in a single direction or in both directions. The 2560P Polarization Stabilizer has two optical fiber connectors mounted on the front panel: an input connector to receive the input light beam and an output connector to couple the polarization state stabilized light beam downstream. Specifications. Operating wavelength: 1260 to 1650 nm standard. Tracking time: < 20 ms. SOP accuracy: < 0.1 dB. Repeatability: < 0.1 dB. Insertion loss: 0.8 dB typical, 1.2 dB max. Return loss: > 50 dB. Isolation in orthogonal polarization: 20 dB. Minimum optical input: -13 dBm. Optical power handling: 20 dBm maximum.
