Trace Display Window
Click "Open..." under the "File" menu to open a trace file, and a trace curve will display in the
trace display window (Figure 7-7). 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. In
Figure 7-7 below, 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.
