Figure 191. OTDR Trace for a Span
Orange, dashed lines show at the Span Start and Span Stop
locations. The trace is zoomed so that the span section fills the
screen.
The launch compensation markers never show with the Span
Start and Span Stop markers because you must turn off launch
compensation to use the span function.
Measurements for events in the span show in green if the
event passed, red if the event failed, or black is there is no
limit for measurement.
Measurements for events outside of the span show in blue.
