The V6C
-
OPM is an optical power meter
designed to attach to ViewConn
®
. It
adds a new dimension to ViewConn’s
capabilities, making ViewConn a cost-
effective and user-friendly 3-in-1 device
for connector-endface inspection,
cleaning, and optical power testing.

I. Operation
After turning on ViewConn, the green LED on
VC6-OPM will light and you will see the
startup screen on the display (Figure 2). After
~5 seconds, the display will automatically
switch to an optical power measurement
page.
Figure 3 shows a typical power measurement
screen, which indicates your selected
operating wavelength as well as the
measured results on optical power and light
modulation frequency.
Figure 1
Figure 2
The Lightel VC6
-
OPM attaches to
ViewConn (Figure 1) and runs on
the power provided by ViewConn.
Connect the -pin jack of the OPM
into the ViewConn -pin receptacle,
and secure the OPM body into the ear
holder of the ViewConn rubber cover.
The “INT/EXT” switch on ViewConn
must be set at the “EXT” position to
use the power meter.
The interchangeable universal 2.5mm
and 1.25mm tips provided with the
VC6-OPM
will allow you to test both PC
and
APC connectors. (Special tips
for individual types of connectors are
also available as options.)

During OPM operation, if you switch
ViewConn to the “INT” setting, the
display will automatically switch to a
connector inspection mode showing
connector video images instead of
showing optical power readings
(Figure 4). ViewConn allows easy and
simple switching between the
connector video inspection and the
power monitoring functions.
If the measured power is too low (< -60dBm) or too high (> +10dBm), you will see alarm
screens (Figures 5 and 6).

II. Button Functions
VC6-OPM contains 5 buttons through which a number of parameter selections or
function selections can be executed.
(1) “
““
“λ
λλ
λ” button
” button” button
” button – for selecting the operating wavelength
(2) “mW/dB/dBm” button
“mW/dB/dBm” button“mW/dB/dBm” button
“mW/dB/dBm” button – for selecting the unit of measured
optical power
By pressing the “λ
” button, you can select the
operating wavelength in a repetitive sequence of
850/1300/1310/1 90/1550/1625nm. A short beep will
sound each time the wavelength is changed
The starting default wavelength on the VC6-OPM is
1550nm.
By pressing the “mW/dB/dBm” button, you can select the
power unit in a repetitive sequence of dBm/mW (or µ
W)/dB.
A short beep will sound each time the unit is changed.
Under the “dB” selection, you are measuring a relative power
(versus the set reference power, see “REF” button).
The starting default measurement unit on the VC6-OPM is dBm.

5
By pressin
g the “REF” button for more than 2 seconds, you will set
the current power as a reference power. Setting is confirmed by
two short beeps. Upon releasing the “REF” button, the display will
start to show the relative power (in dB) versus the reference
power.
To recall your set reference power, briefly press on the “REF”
button. The display will flash 3 times with the current reference
setting and then automatically return to the relative power
measurement.
To reset your reference setting, again press and h
old the
“REF” button for more than 2 seconds. The reference
setting will be
changed to the then current power setting. You
will again hear two short beeps confirming a new setting.
Upon
releasing the “REF” button, the relative power
measurement
will be based on the new reference power.
During power measurement, you can save the power data by
pressing the “SAVE” button. When the data is saved, you wil
l hear
a short beep and the display (Figure 7)
will briefly freeze. It will then
quickly return to a normal measurement mode. The frozen display
will show not only the recorded data, but also the assigned
sequential number (010 in this example).
(3) “REF”
“REF”“REF”
“REF” button – for setting and checking reference power, and
measure a relative power versus the reference
Note: Even when VC6-OPM is powered off, it will remember the last reference
setting. This reference setting will be in the memory when the VC6-OPM is
turned on again.
( ) “SAVE”
“SAVE”“SAVE”
“SAVE” button – for saving measured power data and browsing
saved data
Figure 7
To return to an absolute power measurement mode, simply press
the “mW/dB/dBm” button to select mW or dBm.

6
To delete saved records you must first be in the
browse
mode (i.e
.
after holding “SAVE” button for more than 2 seconds and the
display is showing a selected record.) By pressing the “DEL”
button for more than 2 seconds, you will delete that selected
record. Upon deletion, you will hear two short beeps to indicate
that the deletion has been accomplished. All sequential numbers
for the remaining higher numbered records will be automatically
advanced so that no numbers are missing in the sequence.
To delete all records, enter the browse mode first, and
then simultaneously hold the “DEL” button and the “SAVE” button
for more than 5 seconds.
(5) “DEL”
“DEL”“DEL”
“DEL” button – for deleting saved records
Deleting all records is confirmed by 3 short beeps.
The sequential number of each
record is automatically assigned
with every Save action up to a maximum of 999. If you have
stored 999 records, you will hear four short beeps reminding you
that the storage is full. You will need to delete all or some of the
records in order to gain additional space (refer to “DEL” button)
To browse your saved data, press and hold the “SAVE” button for
more than 2 seconds. Upon entering the browse mode, you will
hear two short beeps. At the same time the display will show the
most recently saved record. (If there were no saved records in the
OPM, you would hear four beeps instead of two .) Starting from
this record, you can browse through all other stored records.
Simply press the Up button (i.e. “λ" button) or the Down button
(i.e. mW/dB/dBm button) respectively.
Briefly pressing the “Save” button again will allow you exit the
browse mode and return to a normal measurement mode.

III. Software Installation
To download the saved data in your VC6-OPM to your computer, you need to install
Lightel’s “DataView” driver and software on your computer.
Before starting installation, connect the power meter to ViewConn and turn it on. The
green power meter light should be on. Then connect the ViewConn mini-B USB cable
to the power meter and the USB jack to your PC (Figure 8).
Figure 8
(A) First time installation of the driver
When you have first connected the V6C-OPM to your PC, the Windows
Hardware Wizard will instruct you to install the driver for the power meter.
Click “Next” to select the driver for your computer’s operating system on the CD
that came from Lightel, and follow the prompts to complete the driver
installation (Figures 9 ~ 12).
Figure 9 Figure 10

(B) Software installation
After installing the driver, click “setup” on the Lightel CD and again follow the
prompts to complete the software installation (Figure 13 – 16).

IV. Downloading and Saving Data to your PC
When you click the “DataView” icon on your computer’s desktop, the software’s
main screen will open (Figure 17).
To download data, the VC6-OPM must be powered (connected to ViewConn,
with ViewConn turned on, and select switch in “EXT” position). The green light on
the power meter should be on, and the power meter connected to your PC
through your USB mini-B cable. An error message will show on bottom of the
application window if this preparation is incomplete. (Figure 18)
Click the “Download” menu item, the saved data will be downloaded from V6C-
OPM to your computer and be displayed as shown (Figure 19 ∼ 20).

You can add a note to any data record (Figure 21). These notes will be included
when you save the downloaded data as text files or as Excel files.
Click on the menu item “Option”, to open a window to include additional information in
the data report (Figure 22). You can change the titles and add your information. Any
empty information fields will not included in the data report.
Click on the “File” menu, and chose “Save as…” to save the downloaded data as a text
file (Figure 23) or an Excel files (Figure 24).
