Fiber optic technology uses light waves to transmit data from one place to another, it uses a glass or plastic threads to transmit that data. Fiber optic cables is a network designed for long distance, high performance and data-networking. Unlike wired cables, fiber optic cables provide reliability, higher bandwidth, higher speed and less data-loss. Distributed fiber optic sensor is a sensor technology that enables real-time and continuous measurements along the entire piece of a fiber optic cable. Contradictory to traditional sensors which relied on sensors measuring at fixed points, distributed fiber optic sensors does not work like traditional one but utilizes the optical fiber itself for sensing purpose. It does not require any additional transducers in its optical path. The interrogator system used in distributed fiber optic sensor works according to a radar-style process, at first it sends a sequence of pulse signals into the fiber and records the return of the scattered pulse ...
