The ZOOM 2 should show approximately -10.00 dBm. If the reading is below -11.00 dBm, the patch cable should be replaced.
Once proper operation has been verified, continue on to the next step.
SET REFERENCE
With the ZOOM 2 and WaveSource still set to 1310nm, press and hold
button on the ZOOM 2 to set it the 1310nm
reference.
The ZOOM 2 display now also should change to show readings in ‘dB’, and will be approximately 0.00 dB.
Press
on the ZOOM 2 twice to set it to 1550nm.
Press
on the WaveSource once to set it to 1550nm.
Press and hold
on the ZOOM 2 to set the reference for 1550nm. Again, the ZOOM 2 display shows readings in ‘dB’,
and will be approximately 0.00 dB.
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 WaveSource to the link under test as shown in Figure 3 below.
Press
on the ZOOM 2 several times until the wavelength is set to 1310nm.
Press
on the WaveSource once to set the wavelength is to 1310nm (the
LED will now be lit).
Record the 1310nm ‘dB’ loss value for the current fiber under test.
