W
Caution
If you disconnected the reference test cord from
the source's output, you must set the reference
again to ensure valid measurements.
1 Verify that the settings described in Table 6-1 are
appropriate. Let the tester and source warm up for 5
minutes.
2 Select Loss/Length mode: On the HOME screen, press
A
Change Test ; then select Loss/Length .
3 Clean the connectors on the cabling to be tested.
4 Connect the tester to the cabling as shown in Figure
6-13.
5 Set the source to the correct wavelength and to
continuous wave output.
6 Press
T
.
7 Select a wavelength for the test. Auto is used with
SimpliFiber sources, as described in the next section.
8 To test at a second wavelength, repeat steps 5
through 7.
9 To save the results, press
s
, select or create a
fiber ID; then press
s
again.
If you tested at two wavelengths, both are stored in
the same record.
Using Auto Wavelength Detection with SimpliFiber
Sources (OFTM-5731 and OFTM-5732 Modules)
A Fluke Networks SimpliFiber source can transmit
wavelength information that can be read by OFTM-5731
and OFTM-5732 modules. This feature helps eliminate
wavelength selection errors when testing in Far End
Source mode.
To use auto wavelength detection, do the following:
1 Verify that the SimpliFiber source is set to Auto
mode. The
Auto LED should be lit. Press
B
if it is
not.
2 Run the Far End Source test, selecting Auto on the
tester's SET SOURCE WAVELENGTH screen.
