4. Common problems and Solutions
4.1 How to observe the optical pulse waveform?
Pulsed light emitted by OTDR
injects into different locations of the
measured optical fiber links, which
can cause loss, such as connection
points, bends and end of the optical
fiber. The measurement results will
be shown in the trace waveform, in
which the horizontal axis represents
the test distance, the longitudinal axis
represents the loss power, and in the
waveform, the measured loss or
reflection is expressed in the event.
