FIBER IN METAL TUBES

SonoSens

Polymer protection

The outer polymer layer provides advanced mechanical protection and guarantees the best possible acoustic transmission.

Perfect fiber coupling

The fibers are in contact with the steel tube the entire cable length, allowing direct coupling for the best acoustic signal.

Perforated steel tube

Perforations enhance the acoustic performance by 40% without compromising the overall mechanical strength of the cable.

We created Sonosens in partnership with another premium manufacturer in the photonics sector, OFS. Together, we developed the most advanced acoustic sensor on the market. Sonosens massively enhances the acoustic transmission for professional Distributed Acoustic Sensing (DAS) applications, offering a 40% better acoustic transmission than common FIMT (Fiber in Metal Tube) constructions.

The design is unique. The sensor is protected with a metallic layer, creating a robust cable that guarantees the maximum lifetime of the application. Ultimately, it has become the popular choice for a wide range of acoustic sensing projects. So if you’re looking for a durable fiber optic sensing cable that outperforms standard cable designs, this is it.

Sonosens has set new standards in acoustic sensing, and it’s a product we’re proud to make available. If you want an expert Distributed Acoustic Sensing solution, get in touch today to speak to one of our experts.
