Polarization Control Platform - NRT-2500
Vorteile
Der NRT-2500 kombiniert einen integrierten optischen Lithium Niobate (LiNbO3) Wellenleiter-Polarisations-Controller für sehr schnelle Polarisationsänderungen mit einer anpassbaren digitalen Signalverarbeitung für funktionale Flexibilität. Zusammen ermöglichen sie es Luna, sieben verschiedene Polarisationsfunktionen anzubieten: Acquirer, Depolarizer, Paddles, Randomizer, Scrambler, Spinner und Tracker in einem Bench-Top Gerät.
Produktfunktionen
Key Features
- Paddles(Set Polarization) – Full polarization control by rotating any of the 5 electro-optic 1⁄4-wave plates to achieve the desired SOP setting with high accuracy, repeatability and resolution.
- Scrambler -Uniform polarization scrambling with full Poincaré Sphere coverage and user-selectable Rayleigh distribution scrambling rates.
- Depolarizer– A single-speed, ultrafast random scrambling mode to reduce the degree of polarization (DOP) of the measured signal or to introduce an extremely fast ΔSOP Impulses for lightning simulation and loop testbeds.
- Spinner – Superfast SOP rotations/scrambling up to 940,000 rad/sec for characterizing the new generation coherent PM-QPSK transceivers.
- Tracker – Fast, robust, and endless polarization tracking with no dropouts or ‘glitches’.
- Acquirer – Acquirer is the automated ‘smart’ paddles mode to drive the SOP to maximize or minimize a feedback signal.
Applications
- Optical Polarization Demultiplexing
- PMD tolerance testing of transponders
- Optical polarization demuxing
- Testing electronic pol-demux
- Optical PMD compensation
- Coherent detection
- Detector calibration
- Ultrafast ∆SOP/∆t event generation
