Clean the tested optic cable, connect with OLT/VIDEO port and ONT port, (SC type
connector), noted with the optic adaptor type, the optical adaptor will be break, and
the tested value will be faulty if the un-matched adaptor connected
1310nm ,upstream, 1490nm, 1550nm downstream, and 3 wavelength measurement
at the same time.
Eg.: The selected threshold name is «test1»(+3dBm,-20dBm,-30dBm). The measured
result displayed: -10dBm (Optical power) at 1310nm upstream measurement as shown
in above figure, as it is within +3dBm (Pass threshold)~-20dBm(Warning threshold),
therefore, it means the optical signal in Pass status and the LED at 1310nm will light up
with green color: If the measured result is between -20~-30dBm, it means the optical
signal in Warn status and the LED at 1310nm will light up with yellow color which
means the optical signal may got problems but still can be used; If the measured result
is out of the range of thresholds, i.e greater than +3dBm or smaller than -30dBm, then
it means the optical signal got problems, the LED at 1310nm will light up with red
color. The same process be used at 1490 and 1550nm wavelengths.
