Optical Time Domain and Reflectometer (OTDR): - is basically an instrument which is used to check the location of fault/break occurrence in a optical fiber link. It consist of light source (laser) which transmits signal and when it reaches to the point of failure,light reflects back and attenuates sharply.This will get captured in OTDR. With the help of graph in OTDR we can calculate the exact location for the fault in Optical Link.
