1. Product Description of OFSCN® 300°C Micro All-Metal Strain Sensor for OFDR
The OFSCN® Micro All-Metal Strain Sensor is a high-precision sensing unit specifically designed for high-spatial-resolution strain monitoring. Encapsulated in a single-layer, high-elasticity special alloy tube, this sensor is optimized for OFDR (Optical Frequency Domain Reflectometry) technology. Featuring factory-pre-installed end-point anchoring and low-reflection FC/APC connectors, it ensures the linear transfer of structural micro-deformations through the high-modulus metallic sheath to the fiber core, enabling millimeter-level distributed strain measurement.

4. Key Advantages for OFDR Applications of OFSCN® 300°C Micro All-Metal Strain Sensor for OFDR
- Millimeter Spatial Resolution: The continuous rigidity of the alloy tube ensures seamless strain conduction at the millimeter scale, fully utilizing the high-spatial-resolution capabilities of OFDR.
- High-Modulus Coupling: Unlike plastic jackets, the special alloy tube possesses a significantly higher elastic modulus, enabling the lossless transfer of micro-strains to the fiber core.
- Low Signal Noise: The factory-polished FC/APC connectors minimize Fresnel reflections, drastically improving the Signal-to-Noise Ratio (SNR) for Rayleigh backscatter analysis.
