Distributed Fiber Optic Sensor (DFOS) is a type of sensor that uses a network of fibers to measure physical parameters or conditions such as temperature, pressure, strain, vibration, or acoustic signals. Unlike traditional sensors that measure a single point, DFOS can measure multiple points along a distributed fiber, allowing for more accurate and comprehensive measurements. This type of sensor is highly reliable and can be used in harsh environments such as in oil & gas pipelines or in hazardous areas. DFOS can provide real-time monitoring and feedback on the health and performance of assets, helping to improve safety and efficiency.
