At the beginning of July at Wires&Bytes test center a climatic test has been conducted to check the temperature resistance of Non-Metallic MultiSense. The test lasted for 6 hours, and the cable withstood 3 cycles of exposure to temperatures from -60°C to +85°C successfully.

This potentially means that Non-Metallic MultiSense can be used in different environments having almost no restrictions in outdoor installations. Particularly the cable can be buried in the ground or integrated into structures such as roads, concrete beams and slabs and withstand sub-zero temperatures while providing quality strain temperature and acoustic acquisition data. This time the cable samples were wound on a plywood spool. The second step of the planned climatic tests will be conducted with a loop of a cable.

Non-metallic MultiSense is a design with a gel-filled central PBT loose tube with optical fibers freely placed inside with 4 tight-buffered optical fibers, FRP rods, and outer jacket suitable for all types of DFOS systems and distributed monitoring as well as for simultaneous multiple measurements along with fibers for data communication.
