Case Studies

Pictures of our photodetectors and fiber optic sensing systems

In a project to locate faults in communication fiber-optic cables in Daxing District, Beijing, the client used YB Photonics’ DAS modules and a laptop to quickly pinpoint cable faults on-site.

In Panjin, Liaoning Province, CNPC is using YB Photonics' DAS for well logging.

At an open-air conveyor belt facility in Shanxi Province, China, a customer is using our full-clock synchronous DAS module paired with a 1G high-speed data acquisition card to monitor the condition of the conveyor belt idlers.

Monitoring of unauthorised construction work in the vicinity of telecommunications fibre-optic cables

Boundary security protection test of DAS; fiber optic cable hangs on the fence, when someone touches the system can monitor the vibration information in real time and restore the vibration information.

Testing the real-time demodulation function of a distributed acoustic sensing system (DAS) and restoring sound under the laboratory.

Distributed fiber optic vibration DVS integrated module with fiber length of 20KM is tested under laboratory to test the vibration effect.
