QUICK REFERENCE GUIDES
Optical Power Meter:
ZOOM 2
Fiber Optic Light Source: Laser OWL Series
PART 3 CHECK ADDITIONAL TEST CABLE
–
Disconnect the reference cable from the detector port on the ZOOM 2.
Remove the mating sleeve (
) from between the test cables.
NOTE: the meter will read LO or a very low power level when
disconnected from the source.
Verify the insertion loss of the patch cable and mating sleeve. This number should be as low as possible, but in ideal conditions
should not exceed 0.5 dB.
Ž
Connect the mating sleeve ( ) to the reference cable, then connect the additional test cable ( ) between the mating sleeve ( )
and the ZOOM 2 (Figure 8).
Do NOT disconnect the reference cable from the Laser OWL light source until testing is complete

PART 4 TAKE READINGS
–
NOTE: if testing at both 1310nm and 1550nm, it is recommended
to test all of the fibers at 1310nm first.
Repeat
and
for each fiber in the cable under test until all
fibers have been tested.
Disconnect the patch cables from both ends of the patch panel
and move to the next port on the patch panel.
Then switch both testers to 1550nm, and repeat the tests for
1550nm (using the 1550nm reference cable).
Record the reading for the current fiber under test.
Take the Laser OWL with its cable(s) to one end of the link under test, and take the ZOOM 2 and its cable to the other end.
Connect the ZOOM 2 and Laser OWL with the 1310nm
reference cable to the link under test (Figure 10).
