A meter that evaluates optical fibers based on detecting reflected light. It's used to measure fiber attenuation, evaluate splice and connector joints, and locate faults.
Optical Time Domain Reflectometer. An instrument that measures transmission characteristics of fiber by sending a pulse of light down the fiber and measuring the light scattered across the length and reflected back from the end as a function of time.
Optical Time Domain Reflectometer. A sophisticated fiber test tool that locates fiber breaks, and can determine loss per connection, splice, or segment.
Optical Time-Domain Reflectometer (SONET, AT&T)
Optical time domain reflectometer, a single port fiber optic test instrument, used for the characterization of fiber attenuation, dispersion, uniformity, splice loss, breaks, and length.
Diagnostic equipment used to calculate the length and attenuation of a fiber-optic cable. By sending a short duration laser pulse into one end of the fiber, the fiber's length is calculated by measuring the amount of time it takes for a reflection to return from the other end.
A method of evaluating optical fibers based on detecting backscattered (reflected) light. Used to measure fiber attenuation, evaluate splice and connector joints, and locate faults. Also, the equipment used to perform such measurements (Optical Time Domain Reflectometer).
a test device that measures loss along a fiber by injecting light at one end and measuring how much is reflected all along the length of the fiber. (see Bidirectional Averaging)
Optical Time Domain Reflectometer. An instrument that locates faults in optical fibers or infers attenuation by backscattered light measurements.
Optical Time Domain Reflectometer. An instrument used to measure optical transmission characteristics. The instrument accomplishes this by sending short pulses of light, in a series, down a fiber and then giving a graphic representation of the backscattered light.
Optical time domain reflectometer. An optical test instrument that measures transmission characteristics by sending a short pulse of light down a fiber and observing the reflected, back scattered light.
Optical Time Domain Reflectometer. A method of evaluating optical fibers based on detecting backscattered (reflected) light. An OTDR trace shows fiber attenuation for the system and location and magnitude of any losses from splices, connectors, and fiber anomalies or fiber discontinuities.
Optical time domain reflectometer. An instruments that used backscattered light to find faults in optical fiber and infer loss.
OPTICAL TIME DOMAIN REFLECTOMETER. An instrument that measures transmission characteristics of an optical fibre by sending a short pulse and measuring the return signals resulting from backscatter and reflections.
Optical Time Domain Reflectometer. A device for finding breaks in fibre optic cables or measuring the length.
A device that can be used in fiber networks to detect potential leaks that could be the result of unwanted intrusion.
Optical Time Domain Relectometer. A method of characterising a fibre wherein an optical pulse is transmitted through the fibre and the resulting backscatter and reflections are measured as a function of time. Useful in estimating attenuation coefficient as a function of distance and identifying defects and other localised losses.
