The traditional Optical Time Domain Reflectometer (OTDR), which uses single optical pulse, extends the dynamic range by increasing the pulse width. However, the increment of pulse width will result in the decrease of the spatial resolution. So the high spatial resolution and long dynamic range can’t...
