Distributed Fiber Optic Sensor (DFOS) Market Overview

Distributed sensing technology enables continuous, real-time measurements of the entire length of the fiber optic cable.Unlike traditional sensors, which rely on discrete sensors measured at predetermined points, distributed sensing does not rely on manufactured sensors but USES optical fibers.
Distributed fiber optic sensor (DFOS) is an ideal choice for monitoring critical infrastructure or facilities.These sensors are small in size, low in cost, impervious to electromagnetic interference, and mechanically and chemically compatible with most building materials, making them ideal for building very large monitoring networks.Distributed optical fiber sensor (DFOS) is commonly used to measure parameters in real time and is difficult to obtain at high resolution over long distances.This limitation can be overcome by using distributed sensors.
Distributed optical fiber sensing system usually consists of laser light source, sensing optical fiber (cable) and detection unit. It is an automatic monitoring system.The measurement is based on the principle of backscattering of light transmitted in the optical fiber.Into a certain energy in the optical fiber and the width of laser pulse, it while they are in the optical fiber transmission to the scattering light, after the creation of the state of light scattering in optical fiber damage and the influence of the change, will not be back scattering of light after WDM, detection, demodulation, into the signal is real-time signal processing system can be displayed, and consists of light waves in optical fiber transmission speed and back light echo time for these information.The distributed optical fiber sensing (DFOS) counted in this report only includes the host system, not the sensing optical fiber (cable) and display equipment.

Distributed Fiber Optic Sensors (DFOS) are advanced sensing systems that utilize fiber optic cables to detect changes in temperature, strain, acoustics, and other environmental variables along the entire length of the fiber. These sensors are widely used in industries like oil & gas, civil engineering, power, and security monitoring due to their high sensitivity, real-time monitoring capabilities, and durability in harsh environments.
