In the late 1990s, OTDR industry representatives and the OTDR user community developed a unique data format to store and analyze OTDR fiber data. OTDR tests will generally not correlate with LSPM tests (or often with other OTDRs!) which test the cable plant more like how the cable plant is used by communications equipment, and usually OTDR results are lower, setting up the network owner for a problem when the communications electronics are installed. Its name means that an OTDR checks the reflected li http://www.fiberoptics4sale.com/c/Fiber-Optic-OTDR.htmlOTDR stands for Optical Time Domain Reflectometer. Mainly for test fiber optics. Breaks, poor splices, insufficient bend radius, water intrusion and cladding damage are some of the impairments that can be detected.
How is it used in testing optical fiber and cable? An instrument that uses backscattered Light to find faults in optical Fiber and infer loss. An OTDR may be used for estimating the fiber's length and overall 1 Jun 2015 OTDR is useful for testing fiber optic cables. It can verify splice loss, measure length and find faults. It simply shows you where the cables are What is OTDR? An OTDR is an extremely valuable tool when you are trying to characterize optical fibers.

The OTDR only needs to have access to one end of a fiber to make its measurements. Identifying bottlenecks is the strength of an OTDR, which sends a pulse of light into fiber and measures the light reflected back at each component as the light lost at that component.
