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.

Observe all both of supply and measurement.
Use this instrument under the .
out the following maintenance operations:
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.

– Press the key to Power On the unit. While the unit is in the state of power on, if pressing
down the key and release quickly (less than 2 seconds), the unit will switch to auto power off; if pressing
down the key for longer than 2 seconds, the unit will shut down. If the unit is in threshold setup, time setup
and backlit setup menu, the key becomes ESC key to exit the menu.
– test mode. It is used to switch the test mode - P/F test mode and normal test mode. When the
unit is in time setup, threshold setup and backlit menu, the key is used to increase value.
– It is used to set threshold. Pressing it down for more than 2 seconds enters threshold setup
menu. In threshold setup menu, press and release the key quickly (less than 2 seconds) to switch
wavelength. In time setup menu, this key functions as <left> arrow key.
– unit switching key. Press and release the key quickly (less than 2 seconds) to switch unit
between dB and dBm; pressing the key down for more than 2 seconds enters to time setup menu. In time
setup menu, threshold setup and backlit setup menu, the key is used to decrease value.
– It is used for reference value setup and selection. If pressing it down for more than 2 seconds,
the instrument will take current light intensity as reference to do measurement. If pressing and release the
key quickly (less than 2 seconds), then the key will function as <right> arrow key.

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
Fail threshold, . value represents
measured optical power, then:
1.If , means the power is , the will indicate in ;
2.If means , the will indicate in ;
3.If , means , the will indicate in ;
4.If , means , the will indicate in ;
5.If , means , the will indicate in ;
6.If , means the power is High, the will indicate in .
