Distributed Polarization Crosstalk Measuring Station
Detecting and Minimizing Polarization Crosstalk in PM Fibers
Misalignment: If the main axes of two PM fibers connected by splicing or with a connector are not optimally aligned, local crosstalk can occur. The amplitude depends on the offset angle.
Irregularities in the assembly of a PM fiber produce light crosstalk that can show up distributed continually across a larger fiber section.
External mechanical stress can produce localized or distributed crosstalk with different amplitudes.
LASER COMPONENTS offers the PXA-1000 distributed polarization crosstalk measuring station from General Photonics that is able to measure the polarization crosstalk at specific locations along a fiber: The intensity and the location of discrete polarization crosstalk can be precisely determined to within a few centimeters. If continual or quasi- continual crosstalk occurs in the fiber, the PXA can locate the accumulated crosstalk.
The PXA-1000 is based on a white-light interferometer that filters out the disturbing zero order interferences and minimizes multiple interferences. This reduces "ghost peaks" and makes measurement possible.
The PXA-1000 is suited for the characterization of PM fiber spools, PM fibers, and PM wave-guide structures. If the PM fiber is used as a sensor, the PXA can detect the specific location of changes in mechanical stress.
In addition, the PXA measures the polarization extinction ratio (PER) of optical wave- guide 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.
