Connect the 1300nm mandrel-wrapped patch cable to the detector port on the ZOOM 2.
Press
several times until the ZOOM 2 is set to 1300nm.
Press and hold
on the ZOOM 2 to set the reference for 1300nm. The ZOOM 2 display should show a power reading of
approximately 0.00 dB. This means that the meter and light source have been successfully “zeroed” at 1300nm.
Take Readings
Remove the patch cable from the detector port on the ZOOM 2, and bring both units to the opposite ends of the link under
test.
Connect the ZOOM 2 and Dual OWL to the link under test as shown in Figure 5 below.
Press
several times until the ZOOM 2 is set to 850nm.
Record the reading for the current fiber under test.
Disconnect the patch cables from both ends of the patch panel and move to the next port on the patch panel.
Repeat
and
for each fiber in the cable under test until all fibers have been tested at 850nm.
For testing 1300nm, again connect to the first fiber under test, except this time use the mandrel-wrapped patch cable
connected to the 1300nm port.
