Product information "POS-002 Polarization Tracker"

1060, 1310, 1550 nm; IL <1.2, <0.1 dB; SOP Recovery Time 0.9 ms; Tracking Speed 47 π/s; SOP Accuracy <0.1 dB; RL >50 dB

Lunas’ POS-002 polarization tracker automatically adjusts the state of polarization (SOP) towards a reference SOP, counteracting continuous input SOP variations as fast as 0.9 ms with no resets.

The reference SOP is determined by a feedback signal which can be provided either internally or externally. The internal feedback version (POS-002-I) consists of a fiber squeezer polarization controller, in-line polarization monitor, digital and analog circuits, and proprietary algorithm. The error signal from the polarization monitor is fed back to the polarization controller to maintain a linear SOP at the output. The output fiber for POS-002-I is typically polarization maintaining (PM) fiber with the SOP aligned to its slow axis.

The external feedback version (POS-002-E) replaces the internal polarization monitor with an external analog electrical feedback signal of the user’s choice, such as a voltage proportional to the degree of polarization (DOP) measured by a polarimeter, the bit-error rate (BER) from a BER chip, the RF spectrum of a detected signal, or the optical power after a polarizer. The output fiber is typically single mode (SM) fiber.

Manufacturer "Luna"

Headquartered in Roanoke, VA, USA, Luna develops, manufactures and markets high-definition fiber optic sensing products and fiber optic test and measurement instrumentation . Luna's products are used to measure, monitor, protect and improve critical processes in the healthcare, telecommunications, energy and defense markets. Luna has become a recognized leader in transitioning science to solutions. Luna’s high-definition fiber optic sensing technology allows engineers to test, modify and qualify their designs; efficiently, effectively, and accurately. The HYPERION series of fiber optic sensing interrogators provide many of the advantages of fiber optic systems and distinguishes itself by virtue of high spatial resolution. On the test and measurement side, Luna provides diagnostic and test instrumentation that enables the complete characterization of optical components, assemblies and short-haul networks; providing substantial cost and time savings in the development, production, and maintenance of optical network equipment. Optical backscatter reflectometers (OBR series) enable ultra-high resolution reflectometry with backscatter level sensitivity, while lightwave component and optical vector analyzers extend Luna’s industry-leading optical frequency domain reflectometry (OFDR) platform to manufacturing test and quality control applications for passive optical components.
