FEBUS A1-R | Distributed Fiber-Optic Acoustic Sensing System
Distributed Fiber-Optic Acoustic Sensing Equipment
Vibration Monitoring
Single-end measurement
Phase and Amplitude Monitoring
Easy to install and use
A choice under stringent conditions
As needed, software and interface development.
Advantages Overview
The FEBUS A1-R Distributed Fiber Optic Acoustic Sensing System provides acoustic information at intervals of every 2 meters (typical value) along the kilometers of fiber optic infrastructure deployed. The FEBUS A1-R equipment can also be directly connected to existing fiber optic cables. It only requires that the fiber be single-mode. This system is specially designed and developed, particularly suitable for harsh environments and one-end measurement requirements. Additionally, we offer personalized customization services for the FEBUS A1-R.

• 2-year warranty and optional maintenance plans
Wide application range
The FEBUS A1-R Distributed Optical Acoustic Sensing System is an ideal device for many infrastructure monitoring applications, such as:
Pipe, riser, and oil outlet leakage monitoring
Oil Well Safety (Fracture Monitoring, Flow Monitoring)
Vertical Seismic Analysis
Perimeter Security (Intrusion Detection)
Railway Track/Railway Locomotive Safety Monitoring
Undersea Cables (Impact Testing, Electrical Partial Discharge)
