Product Description
The PXA-1000 is positioned as a polarization-preserving optical fiber full-link distributed measurement platform. It acquires spatially distributed stress information by analyzing the polarization cross-coupling induced by stress. It uses the PM optical fiber itself as the sensing medium, without the need for additional gratings or discrete sensing units. The core features an adapter for single-mode polarization-preserving optical fibers (G.652/G.657), with a measurement distance of up to 10km, a spatial resolution as low as 1cm, a crosstalk measurement range of -90dB to -30dB, and a dynamic range superior to traditional white light interference schemes. It supports scenarios such as raw material fiber quality inspection, fiber looping monitoring, and structural health monitoring (bridges / tunnels / pipelines), with built-in data storage and Ethernet / USB transmission. It caters to both laboratory and outdoor deployment needs, and has passed industrial-grade reliability tests.
Key features
Innovative optical design: Eliminates zero-order interference and multi-coupling interference, with crosstalk noise as low as -90dB, a higher dynamic range, significantly higher measurement accuracy than traditional white light interferometers, capable of capturing tiny stress and crosstalk events.
No grating sensing architecture: Uses PM optical fibers as the natural sensing medium, without the need to attach gratings or deploy discrete sensors. Installation and calibration are extremely simple, suitable for long-distance, complex-path structural health monitoring (such as oil and gas pipelines, large buildings).
