Product Overview:

The BOTDA/DTSS distributed Brillouin fiber-optic temperature and strain sensing system uses Brillouin frequency-shift demodulation and standard communication fiber as a continuous sensing medium. It measures distributed temperature and strain along long linear assets and large infrastructure, supporting condition monitoring, risk warning, and operation data analysis.

Key Features:

• Long-distance online temperature/strain monitoring for submarine cables, OPGW, power cables, and other continuous fiber routes.

• High accuracy and high spatial resolution for abnormal-point location and trend analysis.

• Supports alarm thresholds, historical curves, reports, remote operation, and monitoring platform integration.

Applications:

• Submarine cable, OPGW, and power cable temperature/strain monitoring.

• Oil and gas pipelines, long-distance pipelines, tunnels, and utility corridors.

• Structural health monitoring for bridges, slopes, dams, and rail transit infrastructure.
