Portable Optical Time Domain Reflectometer (OTDR) Market for the Period 2015–2021, Report Examines by Persistence Market Research (PMR)

New York, NY -- (SBWIRE) -- 02/11/2016 -- An Optical Time Domain Reflectometer (OTDR) is an electronic-optical instrument used to characterize optical fiber. An OTDR extracts from the same end of the fiber and makes multiple measurements which are used to detect faults, defects and also measure the amount of signal loss at any point in the single optical fiber or complete network. A proper interpretation of an OTDR trace requires technical training and experience. Optical Time Domain Reflectometers are generally used by service providers, network constructors and operators to characterize each component of the link and to find fault with the network. There are two types of reflections which were used by OTDR, namely "Rayleigh backscattering" and "Fresnel reflection". Rayleigh backscattering reflections helps in calculating the level of attenuation in the fiber as a function of distance. On the other hand, Fresnel reflection is used to detect physical events along the fiber link.
