PART 1 ACCESSORIES REQUIRED FOR THIS PROCEDURE
–
Please note: accessories will vary based on factors such as core size (62.5/125 vs. 50/125), test equipment connector type, and
patch panel connector type. The diagram below should help visualize when selecting the correct accessories to use.
A helpful video regarding choosing patch cables is available on OWL’s website:

PART 2 SET REFERENCE
–
The ZOOM 2 display should change to show readings in ‘dB’, and the power reading should be approximately
0.00 dB (Figure 7). This indicates that the meter and light source have been successfully “zeroed” at 850nm.
NOTE: If also testing at 1300nm, connect the 1300nm reference cable to the ZOOM 2, set both units to
1300nm, then repeat this step.
Press
to power on the Dual OWL. The 850nm indicator LED should be lit by default.
Note: if Encircled Flux compliance is required, use Encircled Flux Mode Controller Cables instead (
).
Press
to power on the ZOOM 2.
Press
to set the ZOOM 2 to the 850nm wavelength.
Connect the ZOOM 2 and Dual OWL together using the mandrel-wrapped patch cable (
Œ
&
) as shown in Figure 5.
The ZOOM 2 should read approximately -20.00 dBm for 62.5/125 OM1 fibers, or around -23.00 dBm for
50/125 OM2/3/4 fibers (Figure 6).
NOTE: each light source port requires its own reference cable
Press and hold
to set the reference for 850nm.
