Autotest in Smart Remote Mode: Test the Fiber Link
WCaution
If you disconnected the test reference cords from
the tester’s or smart remote’s output, you must
set the reference again to ensure valid
measurements.
11
Clean and inspect the connectors on the cabling to be
tested; then connect to the link. The tester shows test
connections for the test method you selected. Figure 10
shows connections for the 1 Jumper method.
12
Turn the rotary switch to AUTOTEST. Verify that the
media type is set to Fiber Loss. Press J Change
Media to change it if necessary.
13
Press Pon the tester or smart remote.

If Open or Unknown appears, try the following:
•
Verify that all connections are good.
•
Verify that the tester at the other end is on. (The
tester cannot activate a sleeping or powered-down
tester at the far end through the fiber modules.)
•
Try different connections at the patch panel.
•
Try changing the polarity of the connections at one
end.
•
Use the visual fault locator to verify fiber continuity.
15
If bi-directional testing is enabled, the tester prompts
you to switch the fibers halfway through the test.
Switch the fibers at the patch panels or adapters (not
at the tester’s ports) at both ends of the cabling.
16
To save the results, press N, select or create a fiber ID
for the input fiber; then press
N. Select or create a
fiber ID for the output fiber; then press
N again.
In the results for Smart Remote mode, Input Fiber and
Output Fiber refer to the fibers connected to the main
tester’s input and output ports. For a bi-directional test,
these are the fibers connected to the main tester’s input
and output ports at the end of the test.
