（1）Open the JW3213PON power meter，first of all click “connect”，connect
JW3213PON power meter to the computer(Click“English”to set the language
of the operation interface to be English )
（2）choose “Upload Data”，click “Upload Test Data”sign，the saved data can
be read on the computer, and saved as a file format.
（3）click the“Delete Test Data” button or“Clear Test Data”to delete the data.
Threshold Setting：
Click“Upload threshold value”icon to read the threshold.

11
From the toolbar, select “Threshold Set”, and right click the Threshold to
type or modify the threshold value.
Calibration
Choose “Calibration”tab, the user can perform user self-calibration
operation also can choose “Factory Reset”mode. For example, the
current optical power at 1310nm is -10dBm, type -10dBm in the text box
of input standard power, and click Calibration tab, then finished the
calibration operation at 1310nm wavelength.
Power ON/OFF
1.Power ON
Press for about two seconds to make the unit power on，Enter
into the PON power meter function , the unit displays as shown in below
figure:

12
As shown in above figure, the LCD will display simultaneously three
wavelengths of 1310nm upstream measurement and 1490nm,1550nm
downstream measurements. When optical signal is present under test,
the optical channel will display power levels in dBm, when optical signal
is not available, then the optical channel will display “LOW”. “ ”indicates
10 minutes auto-off function is activated.The unit will turn itself off after
10 minutes of idle time. Press to close 10 minutes auto-off.
2.Power Off
Press key for about two seconds,to turn off the unit.
PON Power Meter module
PON power meter can simultaneously measure the PON network upstream signals
of 1310 nm, 1490 nm downstream data signal and descending video signal output power
of 1550 nm
After open the instrument, Press to enter into menu operation, Press
“ ” to exit
Press“ ”or“ ”to choose the following settings, and press
“”to choose the function.

13
Use“or ”to choose the required threshold value,(The
thresholds rang and name have already set in the software, and also
download to the instrument, please check with the user manual of Chapter
6 data communication), For example choose threshold and name it as “a”
and press“ ”.
Press“ ” back to the testing menu.
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

14
will be break, and the tested value will be faulty if the un-matched adaptor
connected
Pay attention to the type of the measured optical fiber connectors, does not match the
type of access instrument, may damage the instrument output optical fiber connector,and can not
get the true result.
1310nm,upstream, 1490nm, 1550nm downstream, and 3 wavelength measurement at the same
time.
Eg.: The selected threshold name is “a”(-10dBm,-20dBm,-30dBm). The
measured result displayed: -11dBm (Optical power) at 1310nm upstream
measurements shown in above figure, as it is within -10dBm (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 -10dBm
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.

15
Press“ ”, there will displaying saving on the screen, check with the
upper pic. The data recording series No.is 0002. press“ ” saving, and
“ ” for cancel, and the saving recording can be checked in the “data
view” under “historical data” Menu.
After finish the testing work, keep the connect port clean, so cover the
dusty-cap once finish the work.
Instructions for Normal Optical Power Meter Function⑤
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. Instrument only provide the test of 850nm、
1300nm、1310nm、1490nm、1550nm、1625nm,display “-70dBm”when without
light.
Take 1310nm measurement for example:
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 fiber adaptor,
the non-matched connecting will make the damage of the connector on the
instrument and also make the faulty of the measuring result.
E.g.: 1310nm measurement, after connect with the optic fiber, it will displaying
-20dBm, press“ ”, set the -20dBm as the reference value, and it will also

16
display relative value (dB), see as following:
In order to get the loss between the two measurements, do another time
testing under the first 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:
After finishing testing, cover the dusty cap to keep the optical connector
port to be clean.

VFL module⑥
During the event or break point checking of the short distance optic fiber
and pigtails we can use the VFL function.
First of all, Clean the optic Fiber end-face, and connect it them the VFL
port (FC adaptor), after open the instruments, press “ ” to activate this
function, then can see the visual laser at the breaking point or the end of the
pigtails. Press “ ” to shift the CW and the Hz wavelength. And press
