Distributed FBG Temperature/Strain Cable
When monitoring high sensing points for temperature/strain, distributed FBG cable will be ideal solution for any applications. The FBG array is embedded in a small diameter fiberglass cable that permits the FBG to expand and contract freely with the temperature/strain variation. The packaging protects the fibre and makes the sensor robust and easy to handle and install.

The sensing cables can be provided with standard fibre optics connectors and both standard and armoured pigtails and can be multiplexed together in series and/or parallel to achieve the sensing network required.
