NOTE
the laser source and power meter modules of the AOMM-
FHM2.
It is suggested to turn off the "TWIN" mode when you don't use
it. The output of laser source will be fluctuated.
The function of "TWIN" and Modulation cannot work
together. When "TWIN" mode is on, the modulation of the
laser source module is closed automatically.
Wavelength will be shifted automatically according to the
recognition when the "TWIN" mode of the power meter
module is on. In words, the modulated signal of 270 Hz, 1 kHz
and 2 kHz cannot be recognized and received now.
Operation in „Testing" mode
7
„Testing" is the standard mode of the device. Use the laser source
output of the device (as described above) to measure the attenua-
tion of cables or splitters or use the optical input [1] of the device to
measure the incoming optical power.

though the different wavelength (1490 nm, 1550 nm, 1625 nm, 850
nm, 1300 nm and 1310 nm, see figure below). The instrument
defaults to 1310 nm.
