6.1.2. Connect with the tested optic fiber
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 gure, 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.
6.1.3. Saving the testing record:
Press «Enter», there will displaying saving on the screen, check with the upper pic. The
data recording series No. is 001. press « Enter» saving, and « Cancel» for cancel, and the
saving recording can be checked in the «data view» under «historical data» Menu.
6.1.4.
After nish the testing work, keep the connect port clean, so cover the dusty-cap once
nish the work.

6.2. Instructions for Normal Optical Power Meter Function
6.2.1.
Press button to open the instrument, use button and , to choose
the Optical Power Meter measurement, then press to enter into the selected
function. or Button in this case, is to choose the wavelength. Take 1310nm
measurement for example:
6.2.2. Connect with the tested optic fiber
Clean the optic Fiber end-face, and connect with the PIN port on the instrument (SC/
FC/ST adaptor), noted with the type of the optic ber adaptor, the non-matched
connecting will make the damage of the connector on the instrument and also make
the faulty of the measurement result.
E.g.: 1310nm measurement, after connect with the optic ber, it will displaying
-20dBm, press , set the -20dBm as the reference value, and it will also display
relative value (dB), see as following:
In order to get the loss between the two measurements, do another time
testing under the rst relative output power. The relative value will be calculated
automatically. For example the second time testing of 1310nm output power is
-35dBm, the relative output power will be -15dBm. (relative output power=absolute
output power-reference value -15dBm=-35.00dBm- (-20.00dBm) see as following:
