Silixa iDAS™

Intelligent high-resolution distributed acoustic sensing system

Why choose the iDAS™ system?

iDAS™ is a proven and versatile solution that has been an industry benchmark for distributed fiber optic sensing for years. Choosing this instrument ensures:

• Full digital recording of the acoustic field: The system records not only sound intensity but also complete phase and amplitude information, enabling advanced signal processing (e.g. directional filtering).

• Excellent linear resolution: The ability to precisely locate events down to 1 meter over sections tens of kilometers long.

• Operation with standard fiber: Unlike the Carina system, iDAS™ works on ordinary, inexpensive single-mode (SM) fibers, which significantly reduces the cost of installation on existing infrastructure.

• Stability and reliability: The system is designed for continuous 24/7 operation in the most demanding industrial environments.

• Fast reconfiguration: The ability to remotely change sampling and resolution parameters depending on current monitoring needs.

Technical characteristics:

• True Phase technology: Provides a linear response to the acoustic signal, which is crucial for precise frequency analysis (e.g. recognizing specific types of vehicles or machinery).

• Wide frequency response: The ability to record sounds from very low frequencies (below 1 Hz) up to the ultrasonic range (a dozen or so kHz).

• High channel density: The ability to monitor thousands of points simultaneously using a single main unit.

Main applications:

• Perimeter and security: Detecting intrusion attempts, fence climbing or tunnel digging under borders.

• Infrastructure: Train traffic monitoring, wheel flat detection and road noise monitoring.

• Geotechnics: Pipeline integrity monitoring, leak detection and slope stability monitoring in mines.

• Marine research: Hydroacoustics and monitoring of submarine telecommunications cables.
