WebThe OTDR works by launching a series of high speed optical pulses into a fiber for measurement. Any events along the fiber return a Rayleigh back scatter. The return pulses' strength are measured, integrated, and plotted. What is the Optical Time Domain Reflectometer OTDR Used For? Time domain reflectometers are commonly used for in-place testing of very long cable runs, where it is impractical to dig up or remove what may be a kilometers-long cable. They are indispensable for preventive maintenance of telecommunication lines, as TDRs can detect resistance on joints and connectors as they corrode, and increasing insulation leakage as it degrades and absorbs moisture, long before either leads to catastrophic failures. Using a TDR, it … chvn radio news

WebA reflectometer is usually calibrated to tell you what a stone "most likely" is. For example, if you're looking at a ruby , a reflectometer will quickly tell you if the gem is not corundum. However, that is far from what you need for positive gem identification. Beware of Inaccurate Results Reflectometers are also notoriously inaccurate.
