Turning Optical Fibers into Perimeter Sensors

Stand 2095

9th September 2026


In perimeter security, optical fibers listen. With Koheras MIKRO lasers at the heart of Distributed Acoustic Sensing (DAS) systems, fences, pipelines, and buried fibers can detect footsteps, digging, and vehicles from tens of kilometers away.
The long coherence length and ultra-low phase noise of Koheras MIKRO enable highly sensitive detection. Combined with advanced interrogators and intelligent algorithms, DAS systems can distinguish harmless vibrations from potential threats. The laser’s rugged and stable design supports reliable operation in harsh environments, helping protect critical assets through continuous and precise real-time monitoring.

Further Information

If you are working with distributed acoustic sensing (DAS), coherent transceivers, long-haul subsea cables, or fiber communication network monitoring, visit Hamamatsu Photonics A/S at booth 2095. You can explore the Koheras single-frequency fiber lasers that offer ultra-low noise, unmatched stability, and reliable mode-hop-free operation. These lasers are available across multiple wavelength ranges, including the C- and L-band, and are designed for demanding precision applications. The range combines robust, low-noise seed lasers with power amplification, frequency conversion, and flexible multi-channel integration in one configurable ACOUSTIK system.
