In modern perimeter security, optical fibers don’t just transmit – they listen. With Koheras MIKRO lasers at the core of DAS (Distributed Acoustic Sensing) systems, fences, pipelines, and buried fibers transform into continuous acoustic sensors. These systems detect footsteps, digging, or vehicles from tens of kilometers away.

Koheras MIKRO’s long coherence length and ultra-low phase noise enable highly sensitive interferometric detection. Paired with advanced interrogators and smart algorithms, DAS can distinguish between harmless vibrations and real threats. The rugged, stable laser design ensures uninterrupted performance in harsh environments, allowing critical assets to be monitored in real time – silently, continuously, and with pinpoint accuracy.
