PART 2b - SET REFERENCE (1550nm)
Connect a singlemode patch cable to the 1550nm port on the Laser OWL and the detector port on the ZOOM 2 (Figure 3).
Press
several times until the ZOOM 2 is set to 1550nm.
Press and hold
on the ZOOM 2 to set the reference for 1550nm. 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 1550nm.
PART 3a - TAKE READINGS (1310nm)
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 Laser OWL to the link under test as shown in Figure 4 below.
Press
several times until the ZOOM 2 is set to 1310nm.
