WebJan 22, 2024 · Most models of OTDR allow the user to select the light pulse width parameter injected into the fiber under test. In the case of the same amplitude, a wider pulse produces a larger reflected signal, that is, a higher backscatter level, that is, the larger the width of the light pulse, the greater the dynamic range of the OTDR. WebThe pulse width period is usually expressed in ns. (3) Measuring range (Range): The OTDR measurement range refers to the maximum distance for the OTDR to obtain data samples. The selection of this parameter determines the size of the sampling resolution. The best measurement range is between 1.5 to 2 times the length of the fiber to be tested ...
