Running the Autotest in Far End Source Mode
WCaution
If the reference test cord has been disconnected
from the smart remote’s output since the
reference was set, you must set the reference
again to ensure valid measurements.
1
Turn on the tester and smart remote and let them sit
for 5 minutes. Allow additional time if the fiber
modules have been stored above or below ambient
temperature. For other sources, warm up according to
the manufacturer’s recommendations.
2
Verify that the settings described in Table 7-2 on page
7-14 are appropriate. Clean the connectors on the
cabling to be tested.
3
Connect the tester to the cabling as shown in
Figure 7-18.
4
Verify the source is set to the correct wavelength.
To set the wavelength on a DTX module used as a
source, hold down the button on the smart remote’s
fiber module for 3 seconds. This turns on the output
port at 850 nm (DTX-MFM2/GFM2) or 1310 nm
(DTX-SFM2). Press again to switch to 1300 nm
(DTX-MFM2), 1310 nm (DTX-GFM2), or 1550 nm
(DTX-SFM2).
The LED is red for the shorter wavelength and green
for the longer wavelength.
For other sources, verify the output is set to the correct
wavelength and is in continuous-wave mode.
5
Turn the rotary switch to Autotest. Verify that the
media type is set to Fiber. Press J Change Media to
change it if necessary.
6
Press P, highlight the appropriate wavelength; then
press P again.
7
To save the results, press N, select or create a fiber ID;
then press
Nagain.
