Fibre optic cables can be attached to any type of fence to detect and pinpoint the location of disturbances including cutting, climbing and lifting. Utilising advanced signal processing, nuisance alarms can be minimised without compromising intrusion detection sensitivity. The enhanced oDSP chip can detect DAS signals with a dynamic range of 50+ dB across the entire segment — four times higher than the industry average.

With double the product lifetime and an extended standard operating temperature, the new DAS is built to continuously monitor valuable assets even under challenging conditions. The new DAS achieves a measurement performance that perfectly balances detection sensitivity (probability of detection) and detection reliability (reduced false and nuisance alarm rate). New intelligent commissioning features reduce setup times, while the system is easily integrated into third party software or custom cloud-based solutions.

Chalcogenide glasses are a matchless material as far as mid-infrared (IR) applications are concerned. The well-known advantages of fiber lasers over their bulk counterparts, namely superior stability and beam quality, compactness, cost-efficiency, flexibility, and maintenance-free operation, can only be fully harnessed in the mid-infrared wavelength range with the development of non-existent yet. Surface biotinylation of the fiber tapered sensing zone has been achieved by reactivity of a maleimide function on sulfhydryl moieties of the glassy surface. The unique optical properties of chalcogenide glasses, including a broad transparency window (2–16 μm), high refractive index.
