OLCHING, Germany, Jan. 20, 2015 — The PXA-1000 measuring station from General Photonics measures polarization crosstalk at specific locations along polarization-maintaining (PM) optical fiber.
Based on a white-light interferometer, the device filters out the disturbing zero-order interferences and minimizes multiple interferences. This reduces ghost peaks and makes it possible to detect the intensity and location of discrete polarization crosstalk to within a few centimeters.
The PXA-1000 is suited for the characterization of PM fiber spools, PM fibers and PM waveguide structures. If the PM fiber is used as a sensor, the PXA can detect the specific location of changes in mechanical stress.
It also measures the polarization extinction ratio (PER) of optical waveguide structures, the autocorrelation function of fiber optic light sources, the double refraction of PM fibers and the fiber lengths of single-mode and PM fibers.
The distributor is Laser Components GmbH.
