This button provides two functions:
MM
CW
850nm
1300nm
z
Press and release to cycle through output wavelengths in the
following order:
Dual 850/1300 nm > 850 nm > 1300 nm > dual 850/1300 nm > ...

Press and hold to switch to CW mode at the current
wavelength, then press and hold the button again to select a
single wavelength in the following order:
850 nm > 1300 nm > 850 nm ...
NOTE: To switch back to WAVE ID mode, press and release the
button again.
Measuring Optical Power
NOTE: It is important to keep all optical connections and surfaces clean to ensure
accurate measurements and operation. Always clean reference cables before
conducting tests.
1. Turn on the FPM 101.
2. Select the appropriate fiber optic reference cable. The reference cable fiber type
(SM or MM), must be the same as the type required by the output being measured.
3. Mount the appropriate adapter cap on the FPM 101 port.
4. Connect one end of the
reference cable to the adapter
cap and the other end to the
optical output to be measured.
5. Press the wavelength button
(see
“Wavelength/Backlight”
on page 1) to select the
wavelength matching the
nominal wavelength of the
source being measured. The
selected wavelength is indicated
by
e in the display.
6. Press the power selection
button (see
“dB/dBm/µW” on
page 1) to display power in
dBm, or press and hold to display
power in µW. The power output
is indicated by
f in the display.
