3.6 Loss Testing (FOT-20A and FOT-30A)
To perform loss testing,
1.
Reference the FOT to the light source.
2.
Power off the source unit.
3.
Connect the reference test jumpers to the fiber under test as shown below.
4.
Power on the light source and activate the first wavelength.
5.
Press
d B m / W
to select absolute mode.
6.
Press
λ
s e l e c t
to match the FOT and source wavelengths.
7.
Press
r e f
to access reference mode. The actual insertion loss of the fiber under
test is displayed.
8.
To test at a second wavelength, select a wavelength on the source unit, and
repeat steps 5 to 7.
3.7 Source Operation (FOT-30A)
3.7.1 Turning the Source On or Off
1.
Turn the source on by pressing and holding
s o u r c e
until the source
wavelength and the
2kHz
or
CW
marker are displayed.
2.
Press
C W / 2 k H z
to toggle between continuous and modulated signal output.
3.
Turn the source off by pressing and holding
s o u r c e
until the source
wavelength and the
2kHz
or
CW
marker disappear.
3.7.2 Selecting the Source Wavelength
If your FOT-30A features a dual-wavelength source, press
s o u r c e
to toggle between
the two wavelengths.
3.7.3
WaveWise
Feature
The
WaveWise
feature allows accurate wavelength matching between two
FOT-30As, one used as a source and the other as a power meter while testing power
and loss. It requires no user-intervention. The source incoming wavelength is
automatically detected by the destination power meter.
