An OTDR is a tester for measuring and analyzing the characterization of optical networks. It uses optical time domain reflectometry technology. The purpose of an OTDR is to measure elements at any location of a fiber optic cable. It only needs one end of the cable in order to measure its elements.

OTDR trace is a .sor, .trc, or other format file containing a graph with the data about the measured duct.. Attenuation is a characteristic showing how much power (dB or dBm) is lost at a given location (attenuation at splice, cross) or in a given section of the duct.

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. Some technicians use a power meter and light source (shown here) when making multimode measurements. Others use an OTDR. Yet, both testers routinely give different results. An OTDR is used to detect the fault location in a fiber. As compared to simple VFL (Visual Fault Location) it is a multifunctional mini computer with Key Board, LCD, Pen, etc. As it is clear from the name Reflectometer, it works on the principle of Reflection.

The MAX-715B OTDR/iOLM is optimized for the point-to-point testing and troubleshooting of FTTx architectures, and is ideal for testing short fibers (e.g., inside a CO environment or at FTTA/DAS network installations).

An OTDR is the optical equivalent of an electronic time domain reflectometer.

Its purpose is to detect, locate, and measure elements at any location on a fiber optic link. An optical time domain reflectometer (OTDR) is a device used to precisely detect faults in an optical fiber link of a communication network. Its function includes generation and transmission of a series of high-speed optical pluses within the fiber. OTDR.

OTDR Testing. An Optical Time-Domain Reflectometer or OTDR is a sophisticated test instrument used to probe the characteristics of long optical fibers.

In this role, it is likely to be used to identify point losses, the length of various cables, and to measure return loss. OTDR is basically used to identify and analyze reflective & non-reflective events that cause disturbance in an Optical Fiber Cable link. An OTDR can identify both expected events (like connectors, fiber ends, splices, etc) and unexpected events (like cable cuts, etc). An Optical Time Domain Reflectometer (OTDR) is an instrument used to create a virtual “picture” of a fiber optic cable route. The analyzed data can provide information on the condition and performance of the fibers, as well as any passive optical components along the cable path like connectors, splices, splitters and multiplexers. The second type of reflection used by an OTDR—Fresnel reflection—detects physical events along the link.

--Optical time domain reflectometer (OTDR) is a necessary fiber optic testing tool which use light backscattering technologies to analyze the optical fiber 

An OTDR uses the effects of Rayleigh Scattering and Fresnel Reflections to measure characteristics in your fiber. OTDR, short for optical time-domain reflectometer, is an optoelectronic instrument used to characterize an optical fiber. It can be considered as the optical equivalent of an electronic time-domain reflectometer. OTDR injects a series of optical pulses into the fiber under test. An Optical Time Domain Reflectometer (OTDR) is used in fiber optics to measure the time and intensity of the light reflected on an optical fiber.

It can verify splice loss, measure length and find faults. The OTDR is also commonly used to create a "picture" of fiber optic It is this tightening of requirements for the physical media that represents a challenge for all components used to build and test a transmission path. According to ISO-14763-3, the correct setup for an OTDR uses both launch and receive (tail) cords, but no measurement device on the far end. The gaps in red show the loss at each connector. An OTDR is a tester for measuring and analyzing the characterization of optical networks. It uses optical time domain reflectometry technology.
