• The x-axis displays the distance (km); the
y-axis represents the backscatter power
(dB).
• There are two markers, A and B; click
either one to activate it. To move the
marker, click and drag with the mouse
pointer; the position information will
change accordingly. By moving the marker,
the horizontal distance and vertical power
can be read manually.
• Zooming in and out of the trace features
depends on the activation of a marker. The
sloped line represents backscatter from the
optical fiber. The peaks are reflective
events in the fiber chain.
• The end of the fiber is shown by the
sudden drop in optical power, which is
followed by noise.
• The symbols at the bottom of the window
indicate the type of event.
