Fiber networks usually carry data, but they can also monitor what is happening around them. With Distributed Acoustic Sensing (DAS), existing fibers become continuous sensors that detect and locate vibrations caused by digging, traffic, cable faults, or other disturbances.
Low-noise lasers provide the stable light needed to pick up even small signals over long distances. Combined with advanced interrogators and algorithms, they help operators identify unusual activity, locate potential problems, and respond sooner. This adds a valuable sensing function to existing infrastructure, helping protect critical assets, reduce downtime, and keep optical networks running reliably.

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.
