Product Details

The ixDAS-2000 series distributed acoustic sensor (DAS) interrogators utilize advanced phase-sensitive optical time-domain reflectometry (φ-OTDR) technology, employing optical fibers (cables) as sensors. These interrogators work by emitting laser pulses into the sensing fiber and analyzing the backscattered light signals that return from the fiber. This process allows for the detection of vibration and acoustic information at all points along the fiber, which can extend for several tens of kilometers. The ixDAS-2000 series provides a robust and reliable solution for various critical monitoring and security applications, enhancing safety and operational efficiency across multiple sectors.

Key Features:

Hardware Demodulation: ensures long measurement distances and high precision in positioning.

Environmental Adaptability: designed to operate effectively in various environmental conditions, making it versatile for different applications.

Low Power Consumption: energy-efficient, suitable for long-term deployment in remote areas.

Applications:

Perimeter Security: Effective for monitoring high-speed rail perimeters, critical area perimeters, etc., to detect unauthorized access or disturbances.

Oil and Gas Pipeline Monitoring: Enables continuous monitoring of pipelines for security breaches.

Power Line Monitoring: Assists in maintaining the integrity and safety of power transmission lines.

Optical Cable Routing and Tracing: Useful for managing and monitoring optical cable networks.
