Advanced OTDR Testing
For multimode fiber, 850nm and 1300nm are commonly used. Pulse Width: A narrow pulse (10–30ns) is ideal for testing short fibers, as it provides higher resolution. For longer fibers, a

The following section discusses the following topics: how an OTDR works, the art of selecting the correct pulse width and range, setting the index of refraction (IOR), and calculating the
Setting OTDR Parameters: Pulse Width, Range, Averaging
The OTDR sends out multiple pulses and averages the results to filter out noise and improve the signal-to-noise ratio (SNR). A higher SNR means a
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
OTDR Set-UP
Dynamice range is associated with pulse width and in turn describes length of fiber that can be measured by OTDRs. Always start testing with a
