Southeast Asian Underground Temperature Measurement Fiber Optic Cable Company

FJINNO, AP Sensing, Uptech, Luna, and Solexperts provide advanced fiber optic solutions for underground temperature monitoring in Southeast Asia and Asia.Key Companies and SolutionsFJINNO offers a distributed fiber optic temperature measurement system for cables in trays and trenches. Their system uses temperature sensing optical fibers connected to a central host, providing real-time monitoring, over-temperature alarms, and long-distance coverage with high reliability and low maintenance costs . This solution is suitable for industrial environments and power cable monitoring. AP Sensing specializes in Distributed Temperature Sensing (DTS), Distributed Acoustic Sensing (DAS), and Distributed Temperature & Strain Sensing (DTSS) for underground cables. Their systems detect hotspots, cold spots, mechanical strain, and external impacts, integrating with SCADA for real-time monitoring and predictive maintenance. They also offer Real-Time Thermal Rating (RTTR) to optimize cable performance and prevent failures . Uptech Sensing provides fiber optic monitoring solutions for distributed measurement of temperature, strain, and acoustics. Their patented DTS, DTSS, and DAS equipment allow continuous monitoring of underground cables, pipelines, and civil infrastructure. They also offer full engineering services, including design, installation, commissioning, and integration with control systems . Luna delivers high-definition distributed temperature sensing using Rayleigh backscatter in optical fibers, offering sub-millimeter spatial resolution. Their systems are suitable for embedded installations and provide precise temperature profiles along long fiber runs, ideal for underground cable monitoring . Solexperts provides fibre optic temperature measurement along conventional telecom fibers up to 60 km, using Raman spectroscopy for accurate temperature profiling. Their systems achieve high spatial resolution and can detect leaks or thermal anomalies in underground structures .Technology OverviewDistributed Temperature Sensing (DTS): Measures temperature along the entire fiber length, detecting hotspots and thermal anomalies.Distributed Acoustic Sensing (DAS): Detects vibrations and acoustic signals, useful for identifying mechanical impacts or third-party intrusions.Distributed Temperature & Strain Sensing (DTSS): Combines thermal and mechanical monitoring for comprehensive cable condition assessment.Integration with SCADA: Enables real-time monitoring, alarm management, and predictive maintenance. These companies provide robust, long-distance, and low-maintenance solutions for underground temperature monitoring, suitable for power grids, industrial facilities, and infrastructure projects in Southeast Asia.
