PROLITE-57
1. Introduction
1.1 Summary
PROLITE- is a portable, high quality PON optical
power meter. It is specifically designed to meet the
rapid growth of FTTx market with PON (Passive
Optical Network) technologies. It is capable to
measure all three signals (1310nm, 1490nm and
1550nm) that carry voice, data and video, so-called
triple-play applications along a single fiber.
can measure not only 1490nm and
1550nm optical signal, but also accurately detect and
measure the upstream burst at 1310nm sent from an
ONU while the ONU is in the idle mode. The simple
operation and accurate measurement make
becomes an ideal tool for PON
(suitable for APON, BPON, EPON and GPON
application) installation/acceptance test to ensure that
they meet required standards, and service activation
and troubleshooting.

Any change on the equipment must be carried out exclusively by technical staff.
Follow the described in the Maintenance paragraph.

Discharged batteries
AC operation
Note:
1.- When the battery power is almost out, there will be a
warning of indicator keeps blinking, then please replace
the batteries or plug in AC adapter to charge batteries.
2.- Please make sure that you have turned the instrument
on before charge the batteries, unplug the AC adapter
when the batteries are fully charged.
3.- Please make sure the batteries are well placed
before charge them.
4.- To eliminate the possibility of acid leakage, please
take out the batteries if the unit will not be used for a long
time
If the instrument is mainly used at one location, e.g. in a
laboratory or test department, the AC adapter can be
used to power it instead of batteries. There is a DC input
jack on the left side of the PL-57 instrument casing into
which the output cable of the AC adapter is plugged. And
when the AC adapter is plugged in, the AC Indicator on
the LCD will be displayed.
1.- Power is supplied by the AC adapter even if battery is
fitted. And the battery indicator is not displayed on the
screen when AC adapter is plugged.
2.- Make sure that the operating voltage of the AC
Adapter / Charger is the same as the local AC line
voltage.

4. Preparing for Operation
Unpacking the instrument
Packing material
Checking the package contents
Checking for damage in transit
We suggest that you keep the original packing material. Using the original packing material is your
guarantee of protecting the instrument during transit.
The standard accessories of are as follows:
Main unit
Case strap
After unpacking the instrument, check to see whether it was damaged in transit. This is particularly likely
if the outer casing is clearly damaged. If there is damage, do not attempt to operate the instrument or to
repair it without authorization. Doing so can cause further damage and you may lose your warranty
qualification.

Not only the instrument will display measured optical power value on LCD screen, but also under P/F test
mode its three LED indicators will function with following meanings:
The three LED indicators represent upstream 1310 nm (ONU), downstream 1490 nm (OLT) and 1550 nm
(Video) respectively. The RED color indicates Fail, ORANGE color is Warning and GREEN color means
Pass.
The definitions for the three states (Fail, Warning and Pass) are described as below:
If assuming the instrument’s measuring upper limit as and lower limit as , the “Pass” threshold
value in instrument’s internal setup are , as Warning threshold and as

5.5.2 Test mode switch:
In the test menu, press to switch between normal test mode and P/F test
mode.
Normal test mode means do not setup threshold value but display optical
power directly. In this mode, the LED indicators will not light. The results are
displayed in two units: dB and dBm using dB/dBm key to switch. See Fig. 1.
Unit dBm is to display the actual power
Unit dB is to display a power value relative to reference value. In this mode,
reference value needs to be preset correctly.
P/F test mode means the measured light power comparing to preset threshold
value to determine if the measured light power meets user’s requirement or
not. LCD will display the optical power and current state. The LED indicators
below the LCD display will also change color to match the current state of
measured light. This test mode is very useful in some special cases required.

The user can setup the value. The steps are as following:
In the test menu, pressing key for more than 2 seconds enters to
threshold setup menu – see Fig. 3
In this menu, left side displays wavelength and right side displays threshold
value. Top line indicates system information (date & time) and bottom line
indicates the information of threshold including threshold symbol, threshold
number and name. In this menu, press and release key quickly
(less than 2 seconds) to switch the wavelength among 1310 nm, 1490 nm and
1550 nm. Press ▲ ( ) key to view previous record, ▼ ( ) key to
view next record, key to validate the current threshold value. After
above operation, all P/F mode test results will base on this threshold value.
After finishing the setup, press Power key (less than 2 sec) to exit the setup
menu.

Pressing key for more than 2 seconds enters to time setup menu, see Fig. 4.
In the time setup menu, the key becomes <left> arrow key and key becomes
<right> arrow key - using them to move cursor. When cursor moves to a number, the user can use ▲
( ) key to increase value and ▼ ( ) to decrease value. When cursor moves to “Yes” and
press key for more than 2 seconds, the “Yes” will flash, means the instrument accepts the
time change. During the time setup, the user can press Power key (less than 2 sec) to exit time
menu and back to test menu, then the system time setup remains unchanged.

5.5.5 Unit Switch
When the instrument is in normal test mode, pressing dBm/dB can switch unit between dBm and
dB. Here, the unit dBm is the actual power and unit dB is a power value relative to reference value.
Refer to next section about “Reference value setup”.
When the instrument is in the P/F test mode, pressing dBm/dB key will automatically exit P/F test
mode and switch to normal test mode. Its unit will be in dB.

5.5.6 Reference Value Setup
In the test menu, press key for more than 2 seconds, then the LCD will display in red (see
Fig. 5). This means the instrument choose the current light power as reference value. The test results
afterward are the values after comparing to this reference value. Now, the unit will be in dB and LED
below LCD display will not light.
In the test menu, press and release key quickly (less than 2 seconds), then current reference
value will appear on LCD display. See Fig. 6.
