Distributed Polarization Crosstalk Analyzer
PXA-1000 - General Photonics Corp. (General Photonics)
The PXA-1000 Distributed Polarization Crosstalk (X-Talk) Analyzer is an enhanced white light interferometer that measures space-resolved stress by analyzing stress-induced polarization cross-coupling along a length of polarization maintaining (PM) fiber. The patented design eliminates strong zero-order interference and reduces the multi-coupling interference common in traditional white light interferometers, both of which can cause “ghost” peaks in the measured signal. The removal of the “ghost” peaks enables the PXA-1000 to unambiguously identify the magnitudes and locations of actual x-talk peaks, resulting in higher measurement sensitivity, higher dynamic range, and higher spatial measurement accuracy.
