Optical Time Domain Reflectometry device measures many features in optical fibers. It measures conditions, attenuations, cable length, and many problems.

Distributed Acoustic Sensing Distributed Acoustic Sensing (DAS) is a type of technology that can detect acoustic signals. Sound waves are the most common example of acoustic waves. These waves occur due to the force fields. Acoustic waves are pressure waves after all. The force going through the materials causes pressure replacements. We call these replacement…

Laser is a word of the acronym of Light Amplification by Stimulated Emission of Radiation. Like many technologies, DAS technologies use lasers.
