Web2. Dynamic range is the data measured under the condition of the maximum pulse width and 3 minutes of average time. Dynamic range is the data measured under the condition of 180km/20480ns/3min. 3. Measuring conditions of blind zone: reflection event is within 4Km, reflection strength < -35dB. Measured by the minimum pulse width. 4. WebPulse width is the most important OTDR setting for advanced OTDR analysis. It determines the dead zone and affects the dynamic range of the instrument. Narrow pulse widths allow a technician to see more detail on the trace and identify events that are close together. Longer pulses allow for maximum distance range.
