    An optical time-domain reflectometer (OTDR) is an optoelectronic instrument used to characterize an optical fiber. It is the optical equivalent of an electronic time domain reflectometer which measures the impedance of the cable or transmission line under test. An OTDR injects a series of optical pulses into the fiber under test and extracts, from the same end of the fiber, light that is scatter. Reliability and quality of OTDR equipmentThe reliability and quality of an OTDR is based on its accuracy, measurement range, ability to resolve and. The common types of OTDR-like test equipment are: 1. Full-feature OTDR: 2. Hand-held OTDR and Fiber break locator: 3. RTU in RFTSs:. In the late 1990s, OTDR industry representatives and the OTDR user community developed a unique data format to store and analyze OTDR fiber data. This data was based on the specifications in GR-196, G.
