The OFSCN® fiber optic stress / strain sensor is a distributed fiber optic sensor designed based on the professional BOTDR and BOTDA principles, which can be used for stress / strain testing in various environments.


The OFSCN® fiber optic stress / strain sensor consists of a fiber optic connector, a tightly wrapped stress / strain sensing fiber, a layer-stranded FRP reinforcement, and a polyethylene sheath. The tightly wrapped optical fiber is in direct contact with the FRP reinforcement and the outer sheath, allowing it to sense external stress / strain changes in real-time. The unique FRP layer-stranding structure design makes the OFSCN® fiber optic stress / strain sensor less affected by environmental temperature changes during stress / strain measurements.


The OFSCN® fiber optic stress / strain sensor is particularly suitable for deployment through burial, embedding, pre-burial, etc., and has a wide range of applications in the monitoring of large-scale building health, geological subsidence, pipeline deformation, and more.

Product Features:

- Simple structure that meets the deployment requirements of fiber optic sensors and stress / strain monitoring needs;
- FRP reinforcement, made of the same material as the fiber optic, minimizes the impact of thermal expansion and contraction due to temperature changes;
- High mechanical strength and a wide measurement range, suitable for various applications;
- Prefabricated fiber optic connectors for plug-and-play convenience.

Installation Method:

- Embed directly during concrete pouring;
- Embed by grooving or embedding;
- Attached to the surface of the building structure and reinforce with strengthening elements (surface-mounted);
- Buried directly with pipelines, etc.
