An instrument that allows the characterization of a fibre by the analysis of backscattered light. The OTDR is one of the most useful diagnostic tools in the fibre trade.
An instrument that measures transmission characteristics by sending a series of short pulses of light down a fiber and providing a graphic representation of the back-scattered light.
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.
An instruments that used backscattered light to find faults in optical fiber and infer loss.
An optoelectronic instrument used to characterize an optical fiber.
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.
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.
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.
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.
