How to choose right pulse width on an OTDR
For example, multimode materials require reduced pulse widths, while single-mode fibers require longer pulse widths. The size of your fiber cable is another important factor in picking the

Multimode Optical Fiber Bandwidth Characterization
In this method a laser diode (OFL or RML) is used to inject power into a test fiber and modulated from a low frequency (for an approximately zero reference level) to a high frequency (in excess of the 3 dB
Beginner''s guide to OTDR testing:
Use the shortest pulse width to check the front end including the first connector of the link. Use larger pulse width to reach longer distances and/or to characterize optical splitter (for FTTH/PON).

The FOA Reference For Fiber Optics
If you need short test times you may compromise on a longer pulse width to reduce the noise. If you need more resolution, average more with shorter test pulses.
Choosing the Right Optical Time Domain Reflectometer (OTDR)
To test long fibers, more dynamic range is needed so a wide pulse of light is required. As dynamic range increases, the pulsewidth increases and the dead zone increases (close events won''t be detected by
