Clean the tester's OTDR port and launch fiber
connectors.
Connect the launch fibers to the tester's OTDR port as
shown on the screen and in Figure 3-2, 3-3, or 3-4; then
press
The tester attempts to automatically identify the
launch and receive fiber ends based on the launch
method you selected. If necessary, you can change
these settings on the SET LAUNCH EVENTS screen, as
follows:
Do not set the launch or receive event to a hidden
event. Do not set the receive event to an event
followed by a hidden event. Doing so may make
length and loss results unreliable.
The tester might not identify a low-reflectance
connection, such as an angled physical contact
(APC) connection, as a launch/receive event. These
connections may show as loss events, which you
can manually select to be the launch/receive event.
For Launch Only compensation, highlight the event
that is the end of the launch fiber; then press
