DESCRIPTION:

The VIAVI APM-424(V)5 is a high-performance distributed fibre optic sensing platform engineered for continuous real-time monitoring of temperature, strain, and acoustic events across large-scale infrastructure and industrial environments.

Designed for utility operators, energy providers, transport infrastructure organisations, industrial facilities, and critical infrastructure monitoring applications, the APM-424(V)5 combines distributed sensing technologies within a scalable fibre optic monitoring architecture capable of long-distance environmental and structural diagnostics.

The platform supports:

• Distributed Temperature Sensing (DTS)
• Distributed Temperature and Strain Sensing (DTSS)
• Distributed Acoustic Sensing (DAS)
• Real-time infrastructure monitoring
• Continuous fibre optic diagnostics

The APM-424(V)5 is engineered for:

• pipeline monitoring
• power cable monitoring
• perimeter intrusion detection
• structural health monitoring
• rail infrastructure monitoring
• tunnel monitoring
• leak detection
• vibration analysis
• environmental monitoring
• predictive maintenance

The platform utilises fibre optic sensing technologies to provide continuous distributed measurements over extended infrastructure distances using standard optical fibre as the sensing medium. This enables real-time monitoring without the requirement for multiple discrete sensor installations.

Its modular architecture supports deployment across industrial control environments, remote infrastructure installations, utility monitoring systems, and centralised operations centres requiring automated event detection and continuous asset visibility.

The system supports integration into network management and industrial monitoring environments for alarm generation, event correlation, analytics, and long-term infrastructure condition analysis.
