Distributed Acoustic Sensing (DAS)

The OptoDAS system is an advanced distributed acoustic sensing (DAS) solution that converts optical fibers longer than 150 kilometers into highly sensitive acoustic sensors. It employs frequency scanning technology to achieve low noise and high-resolution phase measurements.

This system has a wide range of applications, including submarine cable monitoring, earthquake and tsunami early warning, and marine life monitoring. OptoDAS supports multi-channel simultaneous monitoring and can coexist with existing telecom optical fibers without requiring dedicated dark fibers.

Equipped with a server-grade recording computer, it offers large-capacity storage and real-time data processing capabilities, along with a comprehensive software suite for instrument control, data management, and visualization analysis.

It serves as a reliable technology support for submarine cable protection and marine safety.
