Distributed temperature sensing is the use of a whole fiber optic cable as a sensor to detect temperature changes in pipes, electrical systems, power cables etc. DTS technology is of particular interest to electrical industry since these fiber optic sensors are not affected by electromagnetic waves. So, how does this technology work? How do we…

So far, we have examined the principles of the scattered laser light in the cable; but what about the cable itself? How do we protect the ultra-thin glass fiber? What are fibers made of? Well, the optic fibers are made of either transparent plastic or glass, so that the light can travel inside the tube.…
