Optical power measurement

To access the Measurement of Optical Power, press the key "Optical power measurement".
Warning: The appliance can measure only one wavelength at a time. If there are several wavelengths,
measurements will be wrong.
Plug the optical fiber at the output of your equipment on to the optical FC APC socket of the appliance.
Measurement of the losses at insertion:
Make a first measurement at the LNB of your installation: press the reference of the desired wavelength. The
appliance will keep this measure as a reference and automatically switches to dB.
Make measurements everywhere on your installation to check losses of the optical signal.
Selection of the displayed wavelength: 1310, 1490 or 1550nm
Selection of the displayed
unit: dBm, mW or dB for the
measures of losses
