17) Review the reference data to ensure that the proper link characteristics
were used.
modify fiber type and fiber length
modify number of connections and splices
18) Press to continue.
19) Press to confirm setting the wavelength reference.
NOTE: if a reference was previously set for this link position, a prompt will appear
asking to replace the reference.
NOTE: most cabling standards support testing for multiple wavelengths, so the
meter may prompt the user to set an additional wavelength. To set the reference
for the additional wavelength, repeat steps 14 through 19. However,
. A separate reference jumper must be used (and wrapped around a mandrel if multimode).
20) Press to begin taking readings. The meter will begin to display power readings.
The FiberMeter is now ready to store readings. Immediate Mode will appear and should be set to display
power in ‘dB’ for PASS/FAIL readings.
While measuring in ‘dB’, the display will show the amount of attenuation in the fiber under test, and whether it
passes or fails and by what amount. Attenuation will always be shown as a negative number. The amount of
optical loss is known by removing the minus sign.
22) Disconnect the patch cord from the FiberMeter. NOTE: remember to keep the patch cord
connected to the light source for the duration of the test.
23) Connect the meter and light source to opposite ends of the link under
test. The display should appear similar to the figure at the right.
24) Once a readings appears, press to store the reading.
25) If this is the first data point stored for this link, a prompt will appear for
entering a more descriptive fiber name. Press to continue.
