Shows the current selected mode: OPM, A-B, B-A, Ref
Wavelength
Displays the currently selected calibration wavelength of the source wavelength used to
measure in bidirectional mode. Typical wavelengths are as follows:
850nm, 980nm, 1300nm, 1310m, 1480nm, 1550nm
OPM Mode
Multimode: 850nm, 1300nm, Single mode: 1310nm, 1550nm
A-B, B-A
Absolute Power
The absolute power is displayed in dBm.
Relative Power
The relative power is displayed in dB. It is the difference between the reference power
at the corresponding wavelength and the measured absolute power.
Internal Temperature
The internal, ambient temperature is displayed in either ºF (Fahrenheit) or ºC (Celsius),
that selection is performed with a USB command.
