Detection of splices of optical fibers with low loss

Abstract

Optical Reflectometer (OTDR-Optical Time Domain Reflectometr) of various types are widely used in almost all stages of the fiber-optic communication systems, from production of fiber optic cable to the construction of fiber-optic communication lines and their operation. OTDR provides a quick and easy diagnosis of the state of fibers, cables and fiber-optic communication lines in general. A new method of analysis allowing visually detect traces of welding with low loss.
