Distributed fiber optic sensing monitoring system

A distributed fiber optic sensing system, in which fiber optic is both a sensing sensitive component and a transmission medium, adopts advanced OTDR technology to detect real-time and online changes in spatial temperature and strain along the entire fiber optic cable. It can facilitate networking to achieve online monitoring, early warning, and fault diagnosis systems, and complete the full lifecycle assessment and management of the measured object.

Plan Introduction

Advantages of the plan

Scheme Description

Dimension's distributed fiber optic OTDR is designed based on modules and platforms, integrating OTDR modules, Raman scattering based DTS modules, Brillouin scattering based DTSS modules, and distributed vibration monitoring DVS modules. It can monitor fiber optic loss, temperature, strain, and vibration in real-time, online, and continuously. It is widely used for fault monitoring and safety warning in the production, laying, operation and maintenance stages of power grids, Realize automated comprehensive performance monitoring and management throughout the entire lifecycle.

Main applications

Troubleshooting and monitoring during the production, laying, and maintenance of power optical cables
Thresholds for overvoltage in overhead cables, pipeline cables, distribution and transmission links
Rate detection and warning
Temperature/strain/sag/icing/vibration monitoring of OPGW
Power cable strain testing for manufacturing, installation, and maintenance
Anti theft and intrusion monitoring of power pipelines, submarine cables, etc
Structural safety inspection of power equipment

Main advantages

•Multi functional: The same instrument enables fiber optic OTDR, temperature, strain, and vibration monitoring

•Platform+modular design, strong compatibility and scalability

•Integrated monitoring system communication and sensing

Multifunctional
The same instrument can achieve fiber optic OTDR, optical power, temperature, strain, and vibration monitoring, and can be extended through optical switch modules for channel expansion;

Platform+modular design
