Running the Test
Figure 8-1 shows the equipment required for power
meter tests.
1 Select power meter mode: Exit to the HOME screen,
press
A
Change Test ; then select Power Meter . You
do not need to select a fiber type or test limit.
2 Clean the connectors on the reference test cord,
source, and link (if tested).
3 Use the reference test cord to connect the source to
the tester's INPUT port, as shown in Figure 8-2; then
turn on the source.
4 Press
T
; then select the appropriate wavelength.
Auto is used with SimpliFiber sources, as described in
the next section.
5 To change the wavelength after starting the test,
press
B
Change Wavelength .
W
Caution
If the tester shows an error because the power
reading is too high, immediately disconnect the
source from the tester. The tester is not
designed for measuring higher power levels,
such as produced by CATV, optical amplifiers,
and cellular systems.
Figure 8-3 describes the power meter screen.
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 thefollowing:
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 power meter test, selecting Auto on the
tester's SET WAVELENGTH screen.
